When on the other hand reflection stops to challenge and question the fleeting object, not so much to prepare for its possible return as to conceive its present nature, this reflection is turned no less unmistakably in the direction of ideas, and will terminate in logic or the morphology of being. We attribute independence to things in order to normalise their recurrence. We attribute essences to them in order to normalise their manifestations or constitution. Independence will ultimately turn out to be an assumed constancy in material processes, essence an assumed constancy in ideal meanings or points of reference in discourse. The one marks the systematic distribution of objects, the other their settled character.
We talk of recurrent perceptions, but materially considered no perception recurs. Each recurrence is one of a finite series and holds for ever its place and number in that series. Yet human attention, while it can survey several simultaneous impressions and find them similar, cannot keep them distinct if they grow too numerous. The mind has a native bias and inveterate preference for form and identification. Water does not run down hill more persistently than attention turns experience into constant terms. The several repetitions of one essence given in consciousness will tend at once to be neglected, and only the essence itself—the character shared by those sundry perceptions—will stand and become a term in mental discourse.
