“Of all the calamities to which the condition of mortality exposes mankind, the loss of reason appears, to those who have the least spark of humanity, by far the most dreadful, and they behold that last stage of human wretchedness, with deeper commiseration than any other. But the poor wretch, who is in it, laughs and sings perhaps, and is altogether insensible of his own misery.” — Adam Smith, “Of Sympathy,” The Theory of Moral Sentiments
