The sensory acts are accordingly distinguished by their objects.

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.

Thus the same object may supply a practical perception to one person and a speculative one to another, or the same person may perceive it partly practically and partly speculatively.

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

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

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

For psychological purposes the most important differences in conation are those in virtue of which the object is revealed as sensed or perceived or imaged or remembered or thought.
