‘No theory ever agrees with all the facts of its domain,
yet it is not always the theory that is to blame. Facts are constituted by
older ideologies, and a clash between facts and theories may be proof of
progress. It is also a first step in our attempt to find principles implicit in
familiar observational notions.’
‘Considering now the invention, the elaboration and use of
theories which are inconsistent, not just with other theories, but even with experiments,
facts, observations, we may start by pointing out that no single
theory ever agrees with all the known facts in its domain. And the trouble
is not created by rumours, or the result of sloppy procedure. It is created by
experiments and measurements of the highest precision and reliability.’
this ‘trouble’ according to Feyerabend is created by
‘experiments and measurements of the highest precision and reliability’
‘this trouble’ – is only a trouble – if you are troubled by
logical reality –
‘theories’ – ‘experiments’ – ‘facts’ – ‘observations’ – are
from a logical point of view – different characterizations of proposals
and any proposal – be it a ‘theory’ – an ‘experiment’ – a
‘fact’ – an ‘observation’ – is open to question – open to doubt – is uncertain
the ‘trouble’ – so called – is uncertainty
‘experiments and measurements of the highest precision and
reliability’ –
are when you drop the rhetoric (‘highest precision and
reliability’) – proposals –
proposals – open to question – open to doubt – uncertain
if we operate logically – we never leave uncertainty –
and if we operate illogically – we deal in pretension and
rhetoric –
questions can always be asked – doubts raised – and
uncertainties revealed –
pretension and rhetoric – for all their show and bluster –
are grounded in prejudice and ignorance –
our only defence is logic
‘It will be convenient, at this place, to distinguish two
kinds of disagreement between theory and fact: numerical disagreement, and
qualitative failures.
The first case is quite familiar: a theory makes a numerical
prediction and the value that is actually obtained differs from the prediction
made by more than the margin of error. Precision instruments are usually
involved here. Numerical disagreements abound in science. They give rise to an
‘ocean of anomalies’ that surrounds every single theory.
Thus the Copernican view at the time of Galileo was
inconsistent with facts so plain and obvious that Galileo had to call it
‘surely false’. There is no limit to my astonishment’, he writes in a later
work ‘when I reflect that Aristarchus and Copernicus were able to make reason
so conquer sense that, in defiance of the latter, the former became mistress of
their belief.’ Newton’s theory of
gravitation was beset, from the very beginning, by difficulties serious enough
to provide material for refutation. Even today and in the non-relativistic
domain their ‘exist numerous discrepancies between observation and theory’. [Max
Jammer] Bohr’s atomic model was introduced, and retained, in the face of
precise and unshakable contrary evidence. The general theory of relativity was
retained despite Kaufman’s unambiguous experimental results of 1906, and
despite D.C. Miller’s refutation (I am speaking of a refutation because the
experiment was, from the point of view of contemporary evidence, at least as
well preferred as were the earlier experiments of Michelson and Morley). The
general theory of relativity, though surprisingly successful in some domains…failed
to explain 10˝ in the movement of the nodes of Venus and more that 5˝ in the
movement of the nodes of Mars, moreover, it is now again in trouble due to the
new calculations on the motion of Mercury by Dicke and others. All these are
quantitative difficulties, which can be resolved by discovering a better set of
numbers but which do not force us to make qualitative adjustments.’
numerical disagreement –
where the value that is actually obtained – differs from the
prediction made –
Feyerabend says it is just a matter of discovering a better
set of numbers –
any theory is open to question – open to doubt – is
uncertain
its predictions are – uncertain
and any value actually obtained – will be a proposal – open
to question – open to doubt – uncertain
this is the logical reality
any proposal of agreement between theory and fact –
or any proposal of disagreement between theory and
fact –
is open to question – open to doubt – is uncertain –
agreement or disagreement – are pragmatic decisions –
in the face of propositional uncertainty
you decide to endorse the theory in the face of quantitative
difficulties –
or you decide to give more weight – a greater value – to the
quantitative difficulties – than to the theory
any decision either way – will be open to question – open to
doubt – will be uncertain
hoping that a better set of numbers will come along –
may be why you decide to stick with the theory –
and there may well be any number of other reasons
the logical fact remains – any decision here – is a proposal
– and as such is uncertain
‘The second case, the case of qualitative failures, is less
familiar, but of much greater interest. In this case a theory is inconsistent
not with a recondite fact, that can be unearthed with the help of complex
equipment and is known to experts only, but with circumstances which are easily
noticed and which are familiar to everyone.
The first and, to my mind, the most important example of an
inconsistency of this kind is Parmenides’ theory of the unchanging and
homogeneous One which is contradicted by almost everything we know and
experience. The theory has much in its favour and plays a role even today in
the general theory of relativity. Used in an undeveloped form by Anaximander,
it led to the insight by Heisenberg in his theory of elementary particles that
the basic substance, or the basic elements of the universe, cannot obey the
same laws as the visible elements. The theory was supported by Zeno’s
arguments, which showed the difficulties inherent in the idea of a continuum
consisting of isolated elements. Aristotle took these arguments seriously and
developed his own theory of the continuum. Yet the concept of the continuum as
a collection of elements remained and continued to be used, despite the quite
obvious difficulties, until these difficulties were almost removed in the 20th
century.’
‘but with circumstances which are easily noticed and which
are familiar to everyone.’ –
this so called ‘easily noticed and familiar to everyone’ –
whatever that amounts to – will be a proposal – regarding what is seen – what
is experienced –
what you get with Parmenides’ theory of the unchanging and
homogeneous One – is an alternative account of what is experienced
two different proposals –
both open to question – open to doubt – and uncertain
the proposal regarding the ‘easily noticed and familiar to
everyone’ – has a use – and has a function – in everyday life
and as Feyerabend demonstrates here – Parmenides’ proposal
can be shown to have significance in physics
is anyone going to suggest that a proposal of the ‘easily
noticed and familiar to everyone’ – will function in Heisenberg’s theory of
elementary particles?
or that the unchanging and homogeneous One – will get a good
run on the street?
what we have here is different proposals – different
propositions – that function in different propositional contexts – that have
different uses
yes you can put them side by side – and pretend a conflict –
but if you do this – all you show is an ignorance of propositional
diversity and use –
we are not dealing here with ‘qualitative failure’ – that is
rubbish
what we have is propositional difference – plain and
simple
‘Yet the concept of the continuum as a collection of
elements remained and continued to be used, despite the quite obvious
difficulties, until these difficulties were almost removed in the 20th
century.’ –
proposals / theories – will remain significant if they have
a use –
difficulties come and go –
what remains is propositional uncertainty
‘A further example of a theory with qualitative defects is Newton’s
theory of colours. According to this theory, light consists of rays of
different refrangibility which can be separated, united, refracted, but which
are never changed in their internal constitution, and which have a very small
lateral extension in space. Considering that the surface of mirrors is much
rougher than the lateral extension of rays, the ray theory is found to be
inconsistent with the existence of mirror images (as is admitted by Newton
himself): if light consists of rays, then a mirror should behave like a rough
surface, i.e. it should look to us like a wall. Newton
retained his theory, eliminating the difficulty with the help of an ad hoc
hypothesis: ‘The reflection of a ray is effected, not by a single point of the
reflecting body, but by some power of the body which is evenly diffused all
over its surface.
In Newton’s case
the qualitative discrepancy between theory and fact was removed by an ad hoc
hypothesis. In other cases not even this very flimsy manoeuvre is used: one
retains the theory and tries to forget its shortcomings. An example of
this is the attitude towards
Kepler’s rule according to which an object viewed through a
lens is perceived at the point at which the rays travelling from the lens
towards the eye intersect. The rule implies that an object situated at the
focus will be seen infinitely far away.
‘But on the contrary’, writes Barrow, Newton’s teacher and
predecessor at Cambridge, commenting on this prediction, ‘we are assured by
experience that [a point situated close to the focus] appears variously
distant, according to the different situations of the eye … And it does almost
never seem further off than it would be if it were beheld with the naked eye;
but on the contrary, it does sometimes appear much nearer …All of which
does seem repugnant to our principles.’ ‘But for me’, Barrow
continues, ‘neither this nor any other difficulty shall have so great an
influence on me, as to make me renounce that which I know to be manifestly
agreeable to reason.’
Barrow mentions the qualitative difficulties, and he
says that he will retain the theory nevertheless. This is not the usual
procedure. The usual procedure is to forget the difficulties, never talk about
them, and to proceed as if the theory were without fault. This attitude is very
common today.
Thus the classical electrodynamics of Maxwell and Lorentz
implies the motion of a free particle is self-accelerated. Considering the
self-energy of the electron one obtains divergent expression for point charges
while charges of finite extension can be made to agree with relativity only by
adding untestable stress and pressures inside the electron. The problem
reappears in the quantum theory, though it is here partially covered by
‘renormalization’. This procedure consists in crossing out the results of
certain calculations and replacing them by a description of what is actually
observed. Thus one admits, implicitly, that the theory is in trouble with
formulating it in a manner suggesting that a new principle has been discovered.
Small wonder when philosophically unsophisticated authors get the impression
that ‘all evidence points with merciless definitiveness in the … direction …
[that] all the processes involving … unknown interactions conform to the
fundamental quantum law.’ [Rosenfeld in Observation and Interpretation, London,
1957, p.44].’
Newton’s ‘some
power of the body which is evenly diffused all over its surface’ –
is hardly empirical – and for that matter barely theoretical
–
but presumably Newton
did not see the mirror problem as a good enough reason to dump the ray theory
and Kepler’s rule – quite obviously does not fit with
veridical visual perception – or what would go for a normal understanding of it
and Barrow – for whatever reason is quite prepared to go
with the theory – against the senses
it is examples like this – which makes you ask the question
– well what really does drive science – what drives scientists?
I think in all honesty – we can only say – we don’t know –
and they don’t know either
yes – we will have theories of science – and of scientists –
but such theories – are open to question – open to doubt – and for all intents
and purposes – uncertain
‘all evidence points with merciless definitiveness in the …
direction … [that] all the processes involving … unknown interactions conform
to the fundamental quantum law’ [Rosenfeld]
do scientists fear that if they represented themselves and
their enterprise as uncertain – they would loose any power they have?
I guess so – but if so – I think they are wrong about that –
I suspect that the uncertainty of science and the scientist
– is already understood by the layman
and further that the public also recognise that uncertain as
it is –
science has great value – and has delivered great benefits
to humanity –
and that it has delivered catastrophes –
understanding and dealing with uncertainty – I would suggest
is the common lot of man –
and it is no big jump to see that the so called ‘authorities’
– paraded before us – are in fact pretenders
I think we need pretence to get through this existence – but
I think too – we can easily see it for what it is –
no more than a tool of survival – that can be of use
‘The problem reappears in quantum theory, though it is here
partially covered by ‘renormalization’. This procedure consists in crossing out
the results of certain calculations and replacing them by a description of what
is actually observed.’
‘renormalization’ – now that’s a good one –
I think Feyerabend is right on the money here when he says –
‘Thus one admits, implicitly, that the theory is in trouble
with formulating it in a manner suggesting that a new principle has been
discovered.’
this leaves quantum theory – in a rather – uncertain
position –
and this I would argue that is a good thing –
and that being in this uncertain position is in fact the
logical reality – for any theory – for any proposal
‘To sum up this brief and incomplete list: wherever we look,
whenever we have a little patience and select our evidence in an unprejudiced
manner, we find that theories fail adequately to reproduce certain quantitative
results, and that they are qualitatively incompetent to a surprising
degree. Science gives us theories of great beauty and sophistication. Modern
science has developed mathematical structures which exceed anything that has
existed so far in coherence and generality. But in order to achieve this
miracle all the existing troubles had to be pushed into the relation
between theory and fact, and had to be concealed, by ad hoc
approximations and by other procedures.’
quantitative results – are proposals – open to question –
open to doubt – uncertain
qualitative results – are proposals – open to question –
open to doubt – uncertain
this ‘miracle’ of coherence and generality – as I see it –
is no miracle at all – it is the on-
going result of the exploration of propositional uncertainty
theory and fact – are propositional categories –
organizational categories – that have proved
to be most useful
what Feyerabend refers to as ‘existing troubles’ – are
propositional uncertainties –
ad hoc procedures – are open to question –
and an ad hoc theory – may well be used to cover
theoretical difficulties – that is it may be a pretence –
this is not good practice
on the other hand – an ad hoc theory – may be a
pragmatic action – the purpose of which is to move things along
in this case – the ad hoc action – enables work to
proceed – while keeping an eye on the issues that need further investigation
any proposal – any propositional action – any propositional
decision – is open to question – open to doubt – is uncertain
‘This being the case, what shall we make of the
methodological demand that a theory must be judged by experience and must be
rejected if it contradicts accepted basic statements? What attitude shall we
adopt towards the various theories of confirmation and corroboration, which all
rest on the assumption that theories can be made to agree completely with known
facts, and which use the amount of agreement reached as a principle of
evaluation? This demand, these theories, are now all seen to be quite useless.
They are as useless as medicine which heals a patient only if he is bacteria
free. In practice they are never obeyed by anyone. Methodologists may point to
the importance of falsifications – but they blithely use falsified theories.
They may sermonize how important it is to consider all the relevant evidence,
and never mention those big and drastic facts which show that the theories
which they admire and accept, like the theory of relativity or the quantum
theory, may be as badly off as the older theories which they reject. In
practice they slavishly repeat the most recent pronouncements of the top dogs
in physics, though in doing so they must violate some very basic rules of their
trade. Is it possible to proceed in a more reasonable manner? Let us see.’
‘what shall we make of the methodological demand that a
theory must be judged by experience and must be rejected if it contradicts
accepted basic statements?’
what do we make of any demand?
a demand is authoritarian rhetoric – and we are best to see
it as logically worthless –
that a theory is to be judged by experience – and rejected
if it contradicts accepted basic statements – is a methodological proposal
– a proposal as to how to proceed –
and as with any proposal – open to question – open to doubt
– uncertain
this judging by experience – proposal – is a propositional
practice that has developed in the culture of science –
and as with other such practices it has its uses and its
limitations –
there is a logic to it – and indeed it can be a pretence
‘What attitude shall we adopt towards the various theories
of confirmation and corroboration, which all rest on the assumption that
theories can be made to agree completely with known facts, and which use the
amount of agreement reached as a principle of evaluation?’
the assumption that theories can be made to agree completely
with known facts –
is an instance of the assumption of certainty –
this assumption is not just fanciful – it is illogical –
theories are proposals – ‘known facts’ – are proposals –
proposals are open to question – open to doubt – uncertain
this assumption – that theories can be made to agree
completely with known facts – is pretentious – and delusional
the amount of agreement reached – as a principle of
evaluation?
well – any principle – any
evaluation – is uncertain –
nevertheless evaluation are made – and must be made – if
there is to be any propositional movement
so if ‘the amount of agreement’ is decided on as a criterion
– fair enough
‘In practice they slavishly repeat the most recent
pronouncements of the top dogs in physics, though in doing so they must violate
some very basic rules of their trade. Is it possible to proceed in a more
reasonable manner?’
yes – human all too human –
is it possible to proceed in a more reasonable manner?
well – it all depends on what you think is reasonable –
I doubt that there will be any general long lasting
agreement here – by those who actually do science – and those who observe and
describe it –
in any case – science will proceed – as it proceeds
and as it proceeds – it will be open to question – open to
doubt – and it will be uncertain
in my view – you can’t get more reasonable than that
‘According to Hume, theories cannot be derived from facts.
The demand to admit only those theories which follow from facts leaves us
without any theory. Hence, science as we know it can only exist if we
drop the demand and revise our methodology.’
derivation – as I see it is – an explanation of the proposal
– of its origin –
an explanation which by the way – is open to question – to
doubt – is therefore – uncertain
my point though is that it is actually irrelevant
where a proposal comes from –
unless of course you are running an argument for a
particular epistemological prejudice
a proposal is put –
whether you want to chase it down to a sense datum – or an
idea – or – nothing – makes no difference –
it has been put –
and so the question is – are you going to proceed with it –
or not?
does it have value in the propositional context that it has
been put in?
and that is the question – the doubt – the uncertainty
‘According to our present results, hardly any theory is
consistent with the facts. The demand to admit only those theories which follow
from the facts leaves us without any theory. (I repeat: without any
theory, for there is not a single theory that is not is some trouble or
another.) Hence, a science as we know it can exist only if we drop this demand
also and again revise our methodology, now admitting counterinduction in
addition to
admitting unsupported hypotheses. The right method
must not contain any rules that make us choose between theories on the basis
of falsification. Rather, its rules must enable us to choose between
theories we have already tested and which are falsified.’
‘Hence, a science as we know it can exist only if we drop
this demand also and again revise our methodology, now admitting
counterinduction in addition to
admitting unsupported hypotheses.’
any demand is just – authoritarian rhetoric –
really any free thinking individual will see through any
demand – from anywhere
it is not a question of admitting – counterinduction – or
unsupported hypotheses –
it is rather seeing that any proposal is valid –
and that any proposal put – is open to question – open to
doubt – is uncertain –
that is the first point
the next thing to say is that whether a proposal has legs –
is a question for those dealing with it
if a proposal is put in a scientific propositional context –
it will be those working in that context who will determine the value of the
proposal
‘The right method must not contain any rules that make us
choose between theories on the basis of falsification. Rather, its rules
must enable us to choose between theories we have already tested and which
are falsified.’
more demands – more rules –
Feyerabend has not been able to get out of the trenches –
his argument is no advance
falsification – verification – are propositional rituals
that the practice of science has developed
at the end of the day whether a proposal is regarded as
verified – or falsified – is logically irrelevant
it is open to question – open to doubt – it is uncertain
‘To proceed further. Not only are facts and theories in
constant disharmony, they are never as neatly separated out as everyone makes
them out to be. Methodological rules speak of ‘theories’, ‘observations’ and
‘experimental results’ as if these were clear-cut well defined objects whose
properties are easy to evaluate and which are understood in the same way by all
scientists’
the ‘fact’ – and the ‘theory’ – are propositional categories
–
any distinction between a ‘theory’ and a ‘fact’ – is
descriptive
we have different descriptions of propositions –
because we have different uses for proposals – for propositions
logically speaking – any proposal – any proposition – is
open to question – open to doubt – is uncertain –
regardless of how it is described or categorized –
regardless of its use or function
‘methodological rules’ – are proposals for procedure –
they are of course – open to question – open to doubt – and
as with any proposal – uncertain
whether one person – understands another’s proposals – in
the way that the person putting the proposal does – is uncertain
we make an assumption here – an assumption of
‘understanding’ – and in everyday life – not to mention science – this
assumption is constantly challenged – and indeed sometimes it appears to be
entirely wrongheaded –
nevertheless we proceed
‘However, the material which a scientist actually has at his
disposal, his laws, his experimental results, his mathematical techniques, his
epistemological prejudices, his attitude toward the absurd consequences of the
theories which he accepts, is indeterminate in many ways, ambiguous, and
never fully separated from the historical background. The material is
always contaminated by principles which he does not know
and which, if known, would be extremely hard to test.
Questionable views on cognition such as the view that our senses, used in
normal circumstances, give reliable information about the world, may invade the
observation language itself, constituting the observational terms as well as
the distinction between veridical and illusory appearance. As a result,
observation languages may become tied to older layers of speculation which
affect, in this roundabout fashion, even the most progressive methodology.
(Example: the absolute space-time frame of classical physics which was codified
and consecrated by Kant.) The sensory impression, however simple, always
contains a component that expresses the physiological reaction of the
perceiving organism and has no objective
correlate. This ‘subjective’ component often merges with the
rest, and forms an unstructured whole which must then be subdivided from the
outside with the help of counter-inductive procedures. (An example of this is
the appearance of the fixed star to the naked eye, which contains the
subjective effects of irradiation, diffraction, diffusion, restricted by the
lateral inhibition of adjacent elements of the retina.) Finally, there are the
auxiliary premises which are needed for the derivation of testable conclusions,
and which occasionally form entire auxiliary sciences.’
‘However, the material which a scientist actually has at his

the material that a scientist actually has at his disposal –
his laws – experimental results – his mathematical
techniques – his epistemological theories (as distinct from epistemological prejudices)
– his attitude toward the consequences of his theories – are proposals
if they are not separated from ‘the’ historical background –
that is because an historical background has been proposed
‘The material is always contaminated by principles which he
does not know and which, if known, would be extremely hard to test’
the ‘material’ – is not ‘contaminated’ – the material is
open to question – open to doubt – the ‘material’ – is uncertain –
if someone proposes a ‘principle’ – in the material –
then it is known –
prior to this proposal – the ‘principle’ – is not there
– it doesn’t exist
it doesn’t exist – unless it is proposed – it is not known –
until it is proposed
once proposed – it is open to question – open to doubt – it
is uncertain
such ‘principles’ / proposals are not hard to test – they
are open to question – open to doubt – they are uncertain
‘Questionable views on cognition such as the view that our
senses, used in normal circumstances, give reliable information about the world,

terms as well as the distinction between veridical and illusory appearance.’
any view is questionable
the ‘language itself’ – is propositional – open to question
–
a distinction between veridical and illusory experience – is
as with any proposal –
open to question
‘As a result, observation languages may become tied to older
layers of speculation which affect, in this roundabout fashion, even the most
progressive methodology.’
if other speculations – ‘older’ or not – are proposed
– so be it
‘The sensory impression, however simple, always contains a
component that expresses the physiological reaction of the perceiving organism
and has no objective correlate.’
the ‘sensory impression’ – is a proposal – and as the
philosophical work in this area shows only too well – the proposal – is open to
question – open to doubt – and uncertain
‘This ‘subjective’ component often merges with the rest, and
forms an unstructured whole which must then be subdivided from the outside with
the help of counter-inductive procedures.’
another proposal –
‘Finally, there are the auxiliary premises which are needed
for the derivation of testable conclusions, and which occasionally form entire auxiliary
sciences.’
well given that the proposal is – logically speaking – uncertain
– yes it can be taken in any direction
‘Consider the case of the Copernican hypothesis, whose
invention, and partial vindication runs counter to almost every methodological
rule one might care to think of today. The auxiliary sciences here contained
laws describing the properties and the influence of the terrestrial atmosphere (meteorology); optical laws
dealing with the structure of the eye and of the telescopes, and with the
behaviour of light; and dynamical laws describing motion in moving systems.
Most importantly, however, the auxiliary sciences contained a theory of
cognition that postulated a certain simple relation between perceptions and
physical objects. Not all these auxiliary disciplines were available in
explicit form, many of them emerged with the observation language, and led to
the situation described at the beginning of the preceding paragraph.*’
[* ‘However, the material which a scientist actually has at
his disposal, his laws, his experimental results, his mathematical techniques,
his epistemological prejudices, his attitude toward the absurd consequences of
the theories which he accepts, is indeterminate in many ways, ambiguous, and
never fully separated from the historical background.’]
Feyerabend here puts that it is the use of auxiliary
sciences – that is auxiliary propositional systems – which leads to the
situation where the material a scientist has at his disposal – is indeterminate
and ambiguous –
yes – science is a theoretical patchwork –
but this is not the reason it is indeterminate or ambiguous
–
indeterminacy and ambiguity – are expressions of uncertainty
the propositions of science – as with the propositions of
any other human acttivity or endeavour – are proposals
from a logical point of view the proposal – is open to
question – open to doubt – is –
uncertain
you can propose an account of a proposition – that analyses
it in term of the propositional systems that have led to it – or contributed to
it – or in fact have been developed from it –
this can be an interesting study – an interesting portrayal
– an interesting proposal
however logically – it is neither here nor there –
the uncertainty of any propositional system is to found in the
uncertainty of any proposition
‘Consideration of all theses circumstances, of observation
terms, sensory core, auxiliary sciences, background speculation, suggest that a
theory may be inconsistent with the evidence, not because it is incorrect, but
because the evidence is contaminated. The theory is threatened
because the evidence either contains unanalysed sensations which only partly
correspond to external processes, or because it is presented in terms of
antiquated views, or because it is evaluated with the help of backward
auxiliary theories.’ The Copernican theory was in trouble for all these
reasons.’
a theory inconsistent with the evidence – because the
evidence is contaminated?
this ‘evidence’ is – proposal – propositions – open to
question – open to doubt – uncertain
in the same way that the theory is open to question – open
to doubt – uncertain
Feyerabend confuses contamination – with uncertainty
I think ‘contamination’ suits Feyerabend better than
uncertainty – for ‘contamination’ has more of a rhetorical ring to it
and frankly – I don’t think Feyerabend understands logical
uncertainty
‘The theory is threatened because the evidence either
contains unanalysed sensations which only partly correspond to external
processes, or because it is presented in terms of antiquated views, or because
it is evaluated with the help of backward auxiliary theories.’
if you understand that the theory is a proposal – that is
uncertain – then the theory is not threatened
and not threatened by unanalysed sensations – or the terms
in which it is presented or any association with auxiliary theories –
these ‘unanalysed sensations’ – ‘the terms of the theory’ –
and its ‘relation to auxiliary theories’ – are proposals –
proposals that are open to question – open to doubt – and
uncertain
a theory gets proposed – it is argued – for and against – it
is accepted – or not – it is proceeded with – or not
that’s the guts of it
and yes you can do an historical / methodological serenade
or hatchet job on its success or on its lack of success
these stories are always good fun to read – and often quite
insightful – but such romances and tragedies – have nothing to do with science
if you are looking for the answer to the question – why one
theory prevailed – and another didn’t – keep looking –
the best you can get here is proposals – open to question –
open to doubt – uncertain –
decisions get made – decisions as to whether to proceed with
a theory – to proceed with the evidence
any decision is open to question – open to doubt – is
uncertain –
the dogs bark and the caravan moves on
‘It is this historico-physiological character of the
evidence, the fact that it does not merely describe some objective state of
affairs but also expresses subjective, mythical and long forgotten views
concerning this state of affairs, that forces us to take a fresh look at
methodology. It shows that it would be extremely imprudent to let the evidence
judge our theories directly and without any further ado. A straightforward and
unqualified judgement of theories by
‘facts’ is bound to eliminate ideas simply because they do not fit into the
framework of some older cosmology. Taking experimental results and
observations for granted and putting the burden of proof on the theory means
taking the
observational ideology for granted without having ever
examined it. (Note the experimental results are supposed to have been obtained
with the greatest possible care. Hence ‘taking observations, etc., for granted’
means ‘taking them for granted after the most careful examination of
their reliability’: for even the most careful examination of an observation does
not interfere with the concepts in which it is expressed, or with the structure
of the sensory image.)’
‘It is this historico-physiological character of the
evidence, the fact that it does not merely describe some objective state of
affairs but also expresses subjective, mythical and long forgotten views
concerning this state of affairs, that forces us to take a fresh look at
methodology.’
it is not this historical-physiological character of
evidence … that forces us to take a fresh look at methodology’
this historical-physiological character of evidence – is a
methodological proposal –
in the same boat as the methodological proposals –
Feyerabend discredits
let’s be clear – methodological proposals are either
propositional directives – before the fact of scientific activity – or they are
descriptions of scientific work – after the fact
methodological directives – can either be rhetoric that
serves an epistemological prejudice –
or they can be guidelines – the point of which is to get the
process of investigation under way
if the former – their point is to serve a prejudice –
if the latter – then they are proposals that may be useful –
as to methodological proposals that are descriptions after
the fact – they are as with any proposal – open to question – open to doubt –
and uncertain –
they may be of use to the scientist – or they may not
‘a fresh look at methodology’ –
is to see it as a propositional activity that is an
ancillary activity to actual science –
and to see it as – open to question – open to doubt –
uncertain
‘It shows that it would be extremely imprudent to let the
evidence judge our theories directly and without any further ado. A
straightforward and unqualified judgement of theories by ‘facts’ is bound to
eliminate ideas simply because they do not fit into the framework of some
older cosmology
well any judgement that is ‘direct and without further ado’
– is unwise
our judgements are open to question
however judgements get made – and yes ideas – get eliminated
–
if they don’t – what kind of ‘judgement’ is it?
as to older cosmologies – most likely they will be tossed –
this won’t be the case however – if these older cosmologies
– are seen to be relevant –
and any claim of relevance will require argument – and
eventually – decision
decision – open to question – open to doubt – and uncertain
–
decision nevertheless
‘Taking experimental results and observations for granted
and putting the burden of proof on the theory means taking the observational
ideology for granted without having ever examined it’ –
yes – this can happen – does happen – science proceeds
‘Now – how can we possibly examine something we use all the
time and presuppose in every statement? How can we criticize the terms in which
we habitually express our observations? Let us see!’
well I find it hard to believe that there would be anyone
dumb enough – and rigid enough – to presuppose ‘something’ – meaning the same
‘something’ – in every statement
however – if we presuppose – then we either know we
presuppose – or we don’t know –
and if we don’t know – we don’t presuppose –
someone else may say you do – but that is only their
interpretation of your statement
if you are aware of a presupposition to your statement
– your presupposition – that is –
you can question it – subject it to doubt – explore its
uncertainty
‘the terms in which we habitually express our observations’ – are open to question –
open to doubt – they are from a logical point of view – uncertain
how can we do it? –
we just do it – if we are interested in proceeding logically
‘The first step in our criticism of commonly-used concepts
is to create a measure of criticism, something with which these concepts can be
compared. Of course, we shall later want to know a little more about the
measuring-stick itself; for example, we shall want to know whether it is better
than, or perhaps not as good as, the material examined. But in order for this
examination to start; there must be a measuring stick in the first place.
Therefore, the first step in our criticism of customary concepts and customary
reactions is to step outside the circle and either invent a new conceptual
system, for example a new theory, that clashes with the most carefully
established observational results and confounds the most plausible theoretical
principles, or to import such a system from outside science, from religion,
from mythology, from the ideas of incompetents, or the ramblings of madmen.
This step is, again, counterinductive. Counterinduction is thus a fact –
science could not exist without it – and a legitimate and much needed move
in the game of science.’

this is methodological pragmatism –
you propose a ‘measuring stick’ – a standard – in order to
start working
the ‘measuring stick’ – is a proposal – open to question –
open to doubt – uncertain

if what Feyerabend here calls the ‘circle’ – is
propositional reality – we never step out of it –
the best that you have here is different proposals –
different propositions – put against each other
different proposals – will clash – because they are different
a new theory / proposal that clashes with ‘the most
carefully established observational results’ – will most likely only get a look
in – and most likely only if there is some catastrophic failure in the original
theory
and a theory ‘that confounds the most plausible theoretical
principles’ – will need a great deal of work – and some very skilful argument if
it is to get a run
in principle there is nothing against proposing – an outsider
the issue is whether it will get enough support to be a
serious contender
who can say?
my hunch is – that it is unlikely
‘the ideas of incompetents’ – ‘the ramblings of madmen’ – I
mean who does Feyerabend think he’s kidding? –
this is just rhetorical rubbish
and I don’t think that the counterinductive argument should
be reduced to this –
what Feyerabend calls counterinduction – the entry of a
complete theoretical outsider – an outsider I might add that is not incompetent
or the ramblings of a madman – but rather an outsider that is competent – and
intelligent – may indeed be valuable – have a place – in exceptional
circumstances –
and in any case this idea of counterinduction is worth
keeping on the table
however the real point here is – who can say in advance
what theories – what evidence – what kind of testing – what standards of
evaluation – what methodologies are to be used?
the best we can hope for is a range of methodological
options
science does – as science does –
it is up to the scientists to decide how they conduct
themselves
we can have this kind of discussion because we know that there
are certain propositional practices that scientists adopt –
that is where we start –
but once we have made this start – we see – very quickly –
that any description of the practice of science – is open to question – open to
doubt – is uncertain
the best methodological approach – is to have a good
understanding of the methodologies that are proposed – that are in use –
to have a critical and open mind on these methods –
and to have an eye to inventing new methodologies – new
approaches
while recognizing – that any method proposed – is open to
question
