The original human impulses are, with personal variations, common to the whole race, and increase in their importance with an increase in the number of those influenced by them.
It may be worth while, therefore, to attempt a description of some of the more obvious or more important political impulses, remembering always that in politics we are dealing not with such clear-cut separate instincts as we may find in children and animals, but with tendencies often weakened by the course of human evolution, still more often transferred to new uses, and acting not simply but in combination or counteraction.
Aristotle, for instance, says that it is 'affection' (or 'friendship,' for the meaning of [Greek: philia] stands half way between the two words) which 'makes political union possible,' and 'which law-givers consider more important than justice.' It is, he says, a hereditary instinct among animals of the same race, and particularly among men.[6] If we look for this political affection in its simplest form, we see it in our impulse to feel 'kindly' towards any other human being of whose existence and personality we become vividly aware.

This impulse can be checked and overlaid by others, but any one can test its existence and its prerationality in his own case by going, for instance, to the British Museum and watching the effect on his feelings of the discovery that a little Egyptian girl baby who died four thousand years ago rubbed the toes of her shoes by crawling upon the floor.

The tactics of an election consist largely of contrivances by which this immediate emotion of personal affection may be set up.

The candidate is advised to 'show himself continually, to give away prizes, to 'say a few words' at the end of other people's speeches--all under circumstances which offer little or no opportunity for the formation of a reasoned opinion of his merits, but many opportunities for the rise of a purely instinctive affection among those present.
