disillusions of the past have not yet produced a complete enlightenment.
The onslaught made in the last century by the transcendental philosophy upon empirical traditions is familiar to everybody: it seemed a pertinent attack, yet in the end proved quite trifling and unavailing. Thought, we are told rightly enough, cannot be accounted for by enumerating its conditions. A number of detached sensations, being each its own little world, cannot add themselves together nor conjoin themselves in the void. Again, experiences having an alleged common cause would not have, merely for that reason, a common object. Nor would a series of successive perceptions, no matter how quick, logically involve a sense of time nor a notion of succession. Yet, in point of fact, when such a succession occurs and a living brain is there to acquire some structural modification by virtue of its own passing states, a memory of that succession and its terms may often supervene. It is quite true also that the simultaneous presence or association of images belonging to different senses does not carry with it by intrinsic necessity any fusion of such images nor any notion of an object having them for its qualities. Yet, in point of fact, such a group of sensations does often merge into a complex image; instead of the elements originally perceptible in isolation, there arises a familiar term, a sort of personal presence. To this felt presence, certain instinctive reactions
