'For the person or persons that hold dominion, can no more combine with the keeping up of majesty the running with harlots drunk or naked about the streets, or the performances of a stage player, or the open violation or contempt of laws passed by themselves than they can combine existence with non-existence'.

- Benedict de Spinoza. Political Treatise. 1677.

on certainty 134


134. After putting a book in a drawer, I assume it is there, unless…. “Experience always proves me right. There is no well attested case of the book’s (simply) disappearing.” It has often happened that the book has never turned up again, although we thought we knew for certain where it was. – But experience does really teach that a book, say, does not vanish away. (E.g. gradually evaporate.) But is it this experience with books etc. that leads us to assume that such a book has not vanished away? Well, suppose we were to find that under particular novel circumstances books did vanish away. – Shouldn’t we alter our assumption? Can one give the lie to the effect of experience on our system of assumption?



can one say –

that the effect of experience on our system of assumption –

is false?

one’s experience is uncertain –

one’s assumptions are uncertain

there is no conflict
