It is doubtful whether there is such a thing as impulsive or natural tolerance. Tolerance requires an effort of thought and self-control. Thus, it seems that some artificiality, some posing and pretense, is inseparable from any act or attitude which involves a limitation of our appetites and selfishness. We ought to beware of people who do not think it necessary to pretend that they are good and decent. Lack of hypocrisy in such things hints at a capacity for a more depraved ruthlessness.
