The inalterable elements are taken for granted while those that fluctuate are matters for hope and fear. The character of a man's emotional life is therefore intimately dependent upon the social system under which he lives, since his emotions will be directed toward what is doubtful rather than toward what is certain. If a man's income is fixed, he will not think much about money; if his social position is inalterable, he will not be a snob; if he believes his country's greatness to be unassailable, he will not be a vehement nationalist.
