It is convenient to distinguish the two kinds of experience which have thus been described, the experienc-ing and the experienc-ed, by technical words.

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

When we come to images or memories or thoughts, speculation, while always closely related to practice, is more explicit, and it is in fact not immediately obvious that such processes can be described in any sense as practical.

Psychology is the science of the act of experiencing, and deals with the whole system of such acts as they make up mental life.

The perceptive act is a reaction of the mind upon the object of which it is the perception.

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

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.
