Inevitably, in the secret chemistry of the emotions the feeling of pity for a sick person is imperceptibly bound up with tenderness. - Stefan Zweig

It is only at first that pity, like morphine, is a solace to the invalid, a remedy, a drug, but unless you know the correct dosage and when to stop, it becomes a virulent poison. The first few injections do good, they soothe, they deaden the pain. But the devil of it is that the organism, the body, just like the soul, has an uncanny capacity for adaptation. Just as the nervous system cries out for more and more morphine, so do the emotions cry out for more and more pity, in the end more than one can give. Inevitably there comes a moment when one has to say 'no', and then one must not mind the other person's hating one more for this ultimate refusal than if one had never helped him at all. Yes, my dear Lieutenant, one has got to keep one's pity properly in check, or it does far more harm than any amount of indifference — we doctors know that, and so do judges and myrmidons of the law and pawn-brokers; if they were all to give way to their pity, this world of ours would stand still - a dangerous thing pity, a dangerous thing!

The feeling of self-assurance derived from physical achievement always transfers itself to the mental sphere.

Confidences are always risky: a secret entrusted to a stranger make him less of one. You've given away something of yourself, given him the advantage.
