What is the meaning of the togetherness of the perceiving mind, in that peculiar modification of perceiving which makes it perceive not a star but a tree, and the tree itself, is a problem for philosophy.
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.
Such being the nature of mental life, the business of psychology is primarily to describe in detail the various forms which attention or conation assumes upon the different levels of that life.
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.
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.
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.
But though cognition is not an element of mental action, nor even in any real sense of the word an aspect of it, the distinction of cognition and conation has if properly defined a definite value.
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.
We cannot therefore say that mental acts contain a cognitive as well as a conative element.
The mental act of sensation which issues in reflex movement is so simple as to defy analysis.
Curiosity begins as an act of tearing to pieces or analysis.
You can mark in desire the rising of the tide, as the appetite more and more invades the personality, appealing, as it does, not merely to the sensory side of the self, but to its ideal components as well.
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.
But unfortunately Locke treated ideas of reflection as if they were another class of objects of contemplation beside ideas of sensation.
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 perceptive act is a reaction of the mind upon the object of which it is the perception.
The thing of which the act of perception is the perception is experienced as something not mental.
Money is not energy. Wars would also arise as competing political forces saw opportunities to advance, but military expenditure would simply draw more energy and funds away from maintaining social systems and infrastructure, generally leading to the fragmentation or breakdown of centralised systems of administration, governance, and rule.
