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

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

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.

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.

The interval between a cold expectation and a warm desire may be filled by expectations of varying degrees of warmth or by desires of varying degrees of coldness.

Desire then is the invasion of the whole self by the wish, which, as it invades, sets going more and more of the psychical processes; but at the same time, so long as it remains desire, does not succeed in getting possession of the self.
