The sensory acts are accordingly distinguished by their objects.

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

The mental act of sensation which issues in reflex movement is so simple as to defy analysis.

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

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.

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.

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