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

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.

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 thing of which the act of perception is the perception is experienced as something not mental.

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.

The mental act of sensation which issues in reflex movement is so simple as to defy analysis.

An expectation is a future object, recognised as belonging to me.
