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

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

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.

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.

Mental life is indeed practical through and through. It begins in practice and it ends in practice.

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

The sensory acts are accordingly distinguished by their objects.
