ABSTRACT
The sensible universe which we are now going to study presents the same type of order as the preceding one in so far as it consists of the same relations: succession and global resemblance. But it is of another variety in so far as its terms are not only external data but also kinesthetic data. For our present purposes, the difference between these two sorts of data does not reside mainly in a qualitative difference, but in the difference of the physical causes which determine their similitudes. To an observer wandering in a motionless world, the resemblance of two external data signifies returning to the same place, whereas the resemblance of two kinesthetic data marks the repetition of the same change of place. The geometric order of the explored world will then be translated by various combinations of the successions and resemblances according to whether external data or “sensations of movement” form the resemblances.
