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

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

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

Such being the nature of mental life, the business of psychology is primarily to describe in detail the various forms which attention or conation assumes upon the different levels of that life.

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.

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.
