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

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

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.

The sensory acts are accordingly distinguished by their objects.

It is convenient to distinguish the two kinds of experience which have thus been described, the experienc-ing and the experienc-ed, by technical words.

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

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