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

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

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

An object is not first imagined or thought about and then expected or willed, but in being actively expected it is imagined as future and in being willed it is thought.

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.
