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

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.

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

We cannot therefore say that mental acts contain a cognitive as well as a conative element.

For psychological purposes the most important differences in conation are those in virtue of which the object is revealed as sensed or perceived or imaged or remembered or thought.

Both expectations and memories are more than mere images founded on previous experience.

It may be added, to prevent misunderstanding, that when I speak of contemplated objects in this last phrase as objects of contemplation, the act of contemplation itself is of course an enjoyment.
