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

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

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.

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

Hence, in desiring, the more the enjoyment is delayed, the more fancy begins to weave about the object images of future fruition, and to clothe the desired object with properties calculated to inflame the impulse.

It may be added, to prevent misunderstanding, that when I speak of contemplated objects in this last phrase as objects of contemplation, the act of contemplation itself is of course an enjoyment.
