Although there are some points where they touch one another, there is a fundamental difference between philosophic detachment and the unassailable insensibility cultivated by the lower order of Hindu yogis or the invulnerable unfeelingness sought by the ancient Stoics. Some part of the philosopher remains an untouched, independent, and impartial observer. It notes the nature of things but does not allow itself to be swept away by the repulsiveness of unpleasant things or lost in the attractiveness of pleasant ones. But this does not prevent him from removing himself from the neighbourhood of the first kind, or from finding pleasure in the second kind. It is the same with his experience of persons. He is well aware of their characteristics; but however undesirable, faulty, or evil they may be, he makes no attempt to judge them. Indeed, he accepts them just as they are. This is inevitable since, being aware of his and their common origin in God, he practises goodwill towards everyone unremittingly.
