‘Finally, the discussion in Chapters 6-13 shows that
Popper’s version of Mill’s pluralism is not in agreement with scientific
practice and would destroy science as we know it. Given science, reason cannot
be universal and unreason excluded. This feature of science calls for an
anarchistic epistemology. The realization that science is not sacrosanct, and
that the debate between science and myth has ceased without having been won by
either side, further strengthens the case for anarchism.’
here Feyerabend prepares the way for his argument for
incommensurable theories in science
to this end he looks at the critical standards it is claimed
by some constitute the content of rational argument
specifically he wants to look at the standards of the
Popperian school
‘These standards are standards of criticism; rational
discussion consists in the attempt to criticize and not in the attempt to prove
or make probable. Every step that protects a view from criticism, that makes it
safe or ‘well founded’, is a step away from rationality. Every step that makes
it more vulnerable is welcome. In addition, it is recommended to abandon ideas
which have been found wanting and it is forbidden to retain them in the face of
strong and successful criticism unless one can present suitable counter
arguments. Develop your ideas so that they can be criticized; attack them
relentlessly; do not protect them, but exhibit their weak spots; eliminate them
as soon as their weak spots become manifest – these are some of the rules put forward
by our critical rationalists.
These rules become more definite and more detailed when we
turn to the philosophy of science and, especially, to the philosophy of the
natural sciences.
Within natural sciences, criticism is connected with
experiment and observation. The content of a theory consists in the sum total
of those basic statements which contradict it; it is the class of potential
falsifiers. Increased content means increased vulnerability, hence theories of
large content are to be preferred to theories of small content. Increase of
content is welcome, decrease of content is to be avoided. A theory that
contradicts an accepted basic statement is to be given up. Ad hoc
hypotheses are forbidden – and so on and so forth’
‘to prove or to make probable’ –
if by ‘proof’ – you mean
a logical end – to question – to
doubt – to uncertainty –
there is no proof
and if by ‘probable’ – you mean a logical end to question –
to doubt – to uncertainty –
there are no probable statements – hypotheses or theories –
proof and probability – are not logical concepts – they are rhetorical
devices –
devices designed to boost any decision – to proceed
to render any such decision – acceptable and advisable
‘Every step that protects a view from criticism, that makes
it safe or ‘well founded’ is a step away from rationality’ –
no view is logically speaking – beyond question or beyond doubt –
if by ‘well-founded’ – is meant – beyond criticism – then
the well-founded view is a prejudice
uncertainty doesn’t stop us from action – uncertainty is the
ground of action
we act – for whatever reason – and any reason we have – is
open to question – open to doubt – is uncertain
philosophers of science who have failed to accept – or
understand this – have tended to act like moralists – fundamentalists even –
preachers from the pulpit spouting moral imperatives –
this I think is true of the logical positivists – of Popper
– and of Feyerabend –
though Feyerabend camouflages his fundamentalism – in the
rhetoric of ‘anything goes’
and I would say it is not true of Kuhn and Lakatos –
they are – by and large – descriptivists – not
prescriptivists
however the logical reality is that any description
is open to question – open to doubt – and is uncertain
science is what scientists do –
how the scientist proceeds – why the scientist
proceeds as he does – and how he regards his procedure –
is the practice of science –
and yes the practice of science is open to question – open
to doubt – and is uncertain
methodologists – of any persuasion – can put forward their
theories and their insights
and I feel sure that any such proposals will be of interest
to the reflective scientist –
but it is not for the methodologist to legislate or
pontificate
such rhetoric will be seen by the working scientist for what
it is – pretentious
the role of the methodologist is to question – to doubt –
and to explore the uncertainty –
that is scientific practice –
and if necessary to educate the scientist to do the same
‘Now at this point, one may raise two questions.
1. Is it desirable to live in accordance with the
rules of critical rationalism?
2. Is it possible to have both science as we know it
and these rules?
As far as I am concerned the first question is far more
important than the second. True, science and other increasingly depressing and
narrow minded institutions play an important part in our culture, and they
occupy the centre of interest for many philosophers (most philosophers are
opportunists). Thus the ideas of the Popperian school were obtained by
generalizing solutions for methodological and epistemological problems.
Critical rationalism arose from the attempt to solve Hume’s problem and to
understand the Einsteinian revolution, and it was then extended to politics and
even to the conduct of one’s private life. (Habermas and others therefore seem
justified in calling Popper a positivist.) Such a procedure may satisfy a school
philosopher, who looks at life through the spectacles of his own technical
problems and recognizes hatred, love, happiness, only to the extent that they
occur in these problems. But if we consider the interests of man and,
above all, the question of his freedom (freedom from hunger, despair, from the
tyranny of constipated systems of thought and not academic ‘freedom of
the will’) then we are proceeding in the worst possible fashion.
For is it not possible that science as we know it today, as
a ‘search for the truth’ in the style of traditional philosophy, will create a
monster? Is it not possible that it will harm man, turn him into a miserable,
unfriendly, self-righteous mechanism without charm and humour? ‘Is it not
possible’, asks Kierkegaard. ‘that my activity as an objective [or
critico-rational] observer of nature will weaken my strength as a human being?’
I suspect the answer to all these questions must be affirmative and I believe
that a reform of the sciences that makes them more anarchistic and more
subjective (in Kierkegaard’s sense) is urgently needed.’
ok – I understand the view that ‘science and other
depressing and narrow minded institutions play an important part in our
culture’ –
I have been in that mood myself – but it is just one view –
and philosophers as opportunists? –
not my experience – but I can see that they could well be
painted in that way
I find the ideas of the Popperian school – most interesting
proposals –
and if they provide insights for the working scientist –
they will be useful in his work
as to the ‘interests of man’ – that is an open question –
and feel free to throw anything you like into the mix –
but not a good idea to take yourself too seriously here –
‘the interests of man’ – is a work in progress –
as to what constitutes a ‘monster’ – there will be different theories
is it possible that science will turn man ‘into a miserable,
unfriendly, self-righteous mechanism without charm and humour?’
miserable – unfriendly – self righteous – without charm and
humour –
it depends where you are – and who you know –
it seems to me that such characteristics – if they are
displayed – are best understood as circumstantial –
human beings and their propositional practices – are too
variable to be so definitively described –
and as for what will happen – well it is – unknown
best not to let your fears – dictate your theory of
knowledge – or indeed your view of the world –
keep an open mind – whatever mood you’re in
as to ‘reforming the sciences’ – get off your high horse –
leave its shape and form – to the scientists
science is what it is – and will continue to be – whatever
it is –
and whatever it is – is open to question – is open to doubt
– and is uncertain
‘But these are not the problems I want to discuss now. In
the present essay I shall restrict myself to the second question and I shall
ask: is it possible to have a science as we know it and the rules of critical
rationalism as described? And to this question the answer seems to be a firm
and resounding No.
To start with we have seen, though rather briefly, that the
actual development of institutions, idea, practices, and so on, often does
not start from a problem but rather from some irrelevant activity, such as
playing, which, as a side effect, leads to developments which can latter be
interpreted as solutions to unrealised problems. Are such developments to be
excluded? And, if we do exclude them, will this not considerably reduce the
number of our adaptive reactions and the quality of our leaning process?’
‘is it possible to have a science as we know it and the
rules of critical rationalism as described? And to this question the answer
seems to be a firm and resounding No.’
I don’t know if Popper’s ideas are reflected in the actual
practise of science –
and I have to say the same with regard to Feyerabend’s
proposals –
both Popper and Feyerabend have interesting and useful
things to say about scientific practise –
whether they are adopted by practicing scientists – is an
empirical matter –
I don’t see any empirical studies on the matter from Popper
or Feyerabend –
and yes – philo-historical analyses are worth having –
however they are just proposals – in the same boat as any
other proposal – open to question – open to doubt – uncertain
and yes – the actual development of science – may or may not
start with a problem
again – just how scientific work begins – is open to
question
I have to note that we have the makings of a shell game from
Feyerabend –
when is an irrelevant activity – no longer irrelevant? –
watch carefully
and when does not having a problem turn into a problem?
and furthermore there are no ‘unrealised problems’ lurking
in a philosophical underworld
there is only what is put – what is proposed
–.
that is the reality we face – and that is the reality we
deal with –
a propositional reality – open to question – open to doubt –
and uncertain
‘Secondly, we have seen …that a strict principle
falsification, or ‘naïve falsification’ as Lakatos calls it, would wipe out
science as we know it and would never have permitted it to start.’
yes – a strict principle of any kind – would I think wipe
out science as we know it
we don’t operate with strict principles –
yes we have some priests – some politicians and some
philosophers – and some nut cases –
barking out strict principles –
but from what I can see this mob is in the business of
convincing themselves rather than anyone else –
in any case it is just harsh rhetoric – and most people see
through it pretty quickly
just on falsification – from a logical point of view –
any so called falsification – is open to question – open to
doubt – is uncertain
in practice I think falsification is best seen as a propositional
move –
a move in one direction – rather than the other
‘The demand for increased content is not satisfied
either. Theories which effect the overthrow of a comprehensive and
well-entrenched point of view, and take over after its demise, are initially
restricted to a fairly narrow domain of facts, to a series of paradigmatic
phenomena which lend them support, and they are only slowly extended to other
areas……Later on of course the theory is extended to other domains; but
the mode of extension is only rarely determined by the elements that
constitute the content of its predecessors. The slowly emerging conceptual
apparatus of the theory soon starts defining its own problems, and
earlier problems, facts and observations are either forgotten or pushed aside
as irrelevant. ….. A comprehensive theory, after all, is supposed to contain an
ontology that determines what exists and thus delimits the domain of possible
facts and possible questions. The development of new science agrees with these
considerations. New views soon strike out in new directions and frown upon the
older problems…which so much exercised the minds of earlier thinkers.
And they do pay attention to preceding theories, they try to accommodate
their factual core in the manner already described, with the help of ad hoc
hypotheses, ad hoc approximations,
redefinition of terms, or by simply asserting,
without any more detailed study of the matter, that the core ‘follows from’ the
new basic principles. They are ‘grafted on to older programmes with which they
[are] blatantly inconsistent’.
The result of these procedures is an interesting epistemological
illusion: the imagined content of the earlier theories (which is the
intersection of the remembered consequences of these theories with the newly
recognized domain of problems and facts) shrinks and may decrease to
such an extent that it becomes smaller than the imagined content of
the new ideologies (which are the actual consequences of
these ideologies plus all those ‘facts’, laws, principles which are tied
to them by ad hoc approximations or by the say-so of some influential
physicist or philosopher of science – and which properly belong to the predecessor).
‘Theories which effect the overthrow of a comprehensive and
well-entrenched point of view, and take over after its demise, are initially
restricted to a fairly narrow domain of facts, to a series of paradigmatic
phenomena which lend them support, and they are only slowly extended to other
areas……’
a new theory – if viewed exclusively in terms of the old theory – will be restricted
to a narrow domain of facts – the domain of the old theory –
but here we are talking about how the new theory is being
viewed – and how it is being utilized and applied –
it depends on how you look at the new theory –
if you see the new theory in terms of what
might be regarded as its full expression – it’s relation to the older theory –
crucial as that may be in a particular context
– may well be its least important dimension
‘Later on of course the theory is extended to other domains;
but the mode of extension is only rarely determined by the elements that
constitute the content of its predecessors. The slowly emerging conceptual
apparatus of the theory soon starts defining its own problems,
facts and observations are either forgotten or pushed aside as irrelevant. …..
A comprehensive theory, after all, is supposed to contain an ontology
that determines what exists and thus delimits the domain of possible facts and
possible questions.
the extension to other domains need not be later – it may
already have been proposed –
it’s a question of context –
just how important the content of its predecessor is to its
mode of extension – is something we can only speculate on –
it will depend on just what importance it is given by those
involved at the time
‘a slowly emerging conceptual apparatus’? –
look – any theory new or old is – a logically speaking in a
constant state of uncertainty –
the conceptual apparatus will be a propositional work in
progress – whose central characteristic will be uncertainty
and yes – the facts and observations of the older theory
will be put to question – to doubt – and will – if the procedure is logical –
be regarded as uncertain –
and yes – they may be forgotten – they may be pushed aside
decisions get made –
any decision – is open to question –
as to the ‘comprehensive ontology’ – again – propositions
will be put – or if you like assumed or presupposed –
but in any dynamic propositional action – the ontology of a
theory – will be – as with all other propositional dimensions of the theory –
uncertain
‘New views soon strike out in new directions and frown upon
the older problems…which so much exercised the minds of earlier
thinkers. And they do pay attention to preceding theories, they try to

‘blatant inconsistency’ –
logically speaking inconsistency is the fabric of
propositional endeavour and action –
inconsistency is a marker for propositional uncertainty
theoretical action – theoretical development – is an
exploration of propositional uncertainty
the ‘epistemological illusion’ – the ‘imagined’ content of
earlier theories –
look – how a theory – its content is regarded – at any
time – is open to question – is open to doubt – is uncertain –
one could say the whole point of a new theory is that it
reinterprets –
and yes – there will be different – conflicting views on
this –
that is the propositional reality
as Feyerabend’s illustrations above show – there is no
certainty as to the relation between the new and the old theory
really it is a contingent matter –
it is just a question of how the situation is viewed by
those involved at the time –
any proposed relation is open to question – open to doubt –
is uncertain
on the ground – the reality is that perspectives are adopted
– and proceeded with –
until for whatever reason – the propositional state of
affairs is reviewed and re-interpreted
‘To sum up: wherever we look, whatever examples we consider,
we see that the principles of critical rationalism (take falsification
seriously: increase content; avoid all ad hoc hypotheses; ‘be honest’ –
whatever that means; and so on) and a fortiori the principles of logical
empiricism (be precise; base your theories on measurement; avoid vague and
unstable ideas; and so on) give an inadequate account of the past development
of science and are liable to hinder science in the future. They give an
inadequate account of science because science in much more ‘sloppy’ and
‘irrational’ than its methodological image. And, they are liable to hinder it,
because the attempt to make science more ‘rational’ and more precise is bound
to wipe it out, as we have seen. The difference between science and methodology
which is such an obvious fact of history, therefore, indicates a weakness of
the latter, and perhaps of the ‘laws of reason’ as well. For what appears as
‘sloppiness’, ‘chaos’ or ‘opportunism’ when compared with such laws
has a most important function in the development of those
very theories which we today regard as essential parts of our knowledge of
nature. These ‘deviations’, these ‘errors’, are pre-conditions of progress.
They permit knowledge to survive in the complex and difficult world which we
inhabit, they permit us to remain free and happy agents.
Without ‘chaos’, no knowledge. Without a frequent dismissal
of reason, no progress. Ideas which today form the basis of science exist only
because there were such things as prejudice, conceit, passion; because these
things opposed reason; and because they were permitted to have their
way. We have to conclude then, that even within science reason
cannot and should not to allowed to be comprehensive and that it must be
overruled, or eliminated, in favour of other agencies. There is not a single
rule that remains valid under all circumstances and not a single agency to
which appeal can always be made.’
there is no methodological account of science – be that
critical rationalism – or Feyerabend’s so called ‘methodological anarchism’ –
or whatever – that is beyond question – beyond doubt
what we get – at the best – from
these and other methodological proposals – is insights –
suggested ways of proceeding –
suggested methods of evaluation –
science is what it is –
which amounts to saying – it is how
it is described – by whoever proposes a description
it is always a question of how you
see –
some interpret in terms of some
form of rational theory –
Feyerabend sees it as – sloppy –
chaotic – opportunistic
in the absence of description – of
any description at all – science is – unknown
it is made known in terms of
descriptive proposals –
any such proposal is – open to
question – open to doubt – is uncertain –
‘without ‘chaos’, no knowledge’?
forget chaos – what we are dealing
with is propositional uncertainty –
knowledge is our response to the
unknown –
and our responses are uncertain –
logically speaking – there is no
such thing as ‘progress’ – what we have is movement in propositional space
what gets written up as ‘progress’
– is an exercise in rhetoric
Feyerabend’s ‘argument’ regarding
reason – is I would suggest rather chaotic and sloppy itself –
yes – you can run with ‘anything
goes ‘ – and go nowhere
reason is critical analysis –
a rational argument – is any
argument that is up for question – up for doubt – is regarded as uncertain
‘There is not a single rule that remains valid under all
circumstances and not a single agency to which appeal can always be made.’
yes – what we have from Feyerabend
here is not an argument for his so called ‘anarchism’ – rather an argument for
epistemological scepticism
and this is the central problem
with ‘Against Method’ –
where it has value – it is not what
it claims to be –
‘Against method’ – is at its best
where it can be seen to endorse and advocate a methodological scepticism
Feyerabend is in many respects a traditionalist – he sees
scepticism as a useful tool – a means to an end – and the end for Feyerabend is
to defeat his philosophical enemies –
he plays the same tired old game
the radical step – is to see that any methodological
proposal – an indeed – any proposal – is open to question – open to doubt and
is – uncertain
it is to see that uncertainty is the ground and engine of
propositional activity – of propositional life
‘Now we must remember that this conclusion has been drawn on
condition that science as we know it today remains unchanged and that
the procedures it uses must be permitted to determine its future development as
well. Given science, reason cannot be universal and unreason cannot be
excluded. This peculiar feature of the development of science strongly supports
an anarchistic epistemology. But science is not sacrosanct. The restrictions it
imposes (and there are many such restrictions though it is not easy to spell
them out) are not necessary to have general coherent and successful views about
the world. There are myths, there are dogmas of theology, there is metaphysics,
and there are many other ways of constructing a world view. It is clear that a
fruitful exchange between science and such ‘non-scientific’ world-views will be
in even greater need of anarchism than is science itself. Thus anarchism is not
only possible, it is necessary both for the internal progress of
science and for the development of our culture as a whole. And Reason, at last
joins all those other abstract monsters such as Obligation, Duty, Morality,
Truth and their more concrete predecessors, the Gods, which were once used to
intimidate man and restrict his free and happy development: it withers away ….’
‘Given science, reason cannot be universal and
unreason cannot be excluded’ –
the problem with unreason – as in propositional action that
is not open to question – open to doubt – that is regarded as certain – is that
you get nowhere with it – in the sense that you don’t get beyond it –
here I have in mind prejudice in whatever form it takes –
you don’t get beyond it – you don’t move from it –
until you question it – until you take the supposed certainty out of it
passion is interesting – it can be an exploration of
uncertainty – or an obstinate stand against doubt –
that is to say it can be rational or irrational –
I would put that no-one operates rationally under all
circumstances –
and I don’t think that people are essentially – irrational
I think our lives are an uncertain mix of rational and
irrational behaviour
the issue is understanding the difference
‘But science is not sacrosanct. The
restrictions it imposes (and there are many such restrictions though it is not
easy to spell them out) are not necessary to have general coherent and
successful views about the world.’
yes – that I would have thought is
obvious
‘It is clear that a fruitful
exchange between science and such ‘non-scientific’ world views will be in even
greater need of anarchism than is science itself.’
scientific and non-scientific world
views – are proposals – open to question – to doubt – and uncertain
fruitful exchange between different
world views – or should we say – between the proponents of different world
views – is always possible if those involved are open to question – open to
doubt – and can deal with uncertainty
anarchism as such has nothing to do
with it –
where you have bigot against bigot
– there will be no fruitful exchange
Feyerabend’s anarchism – as the
methodology of overthrow – will suit the thugs
‘And Reason, at last joins all those other abstract monsters
such as Obligation, Duty, Morality, Truth and their more concrete predecessors,
the Gods, which were once used to intimidate man and restrict his free and
happy development: it withers away’
these so called ‘abstract monsters’ – are proposals – open
to question – open to doubt – uncertain
Feyerabend here displays his own prejudices – and thus his
ignorance
