But unfortunately Locke treated ideas of reflection as if they were another class of objects of contemplation beside ideas of sensation.

Curiosity begins as an act of tearing to pieces or analysis.

An object is not first imagined or thought about and then expected or willed, but in being actively expected it is imagined as future and in being willed it is thought.

It is more difficult to designate this form of conation on its practical side by a satisfactory name.

You can mark in desire the rising of the tide, as the appetite more and more invades the personality, appealing, as it does, not merely to the sensory side of the self, but to its ideal components as well.

Thus the same object may supply a practical perception to one person and a speculative one to another, or the same person may perceive it partly practically and partly speculatively.

But though cognition is not an element of mental action, nor even in any real sense of the word an aspect of it, the distinction of cognition and conation has if properly defined a definite value.
