"Experience has taught me

 "Experience has taught me that it is wrong and cruel to suspend judgment, that non-judgmentalism is at best indifference to the suffering of others, at worst a disguised form of sadism. How can one respect people as members of the human race unless one holds them to a standard of conduct and truthfulness? How can people learn from experience unless they are told that they can and should change? One doesn't demand of laboratory mice that they do better: but man is not a mouse, and I can think of no more contemptuous way of treating people than to ascribe to them no more responsibility than such mice.”

Theodore Dalrymple (1949-) English psychiatrist and cultural critic.
