reading about the Roman Emperor or the French King; about Seneca, Burrhus, and Thrasea, or Turgot, Malesherbes, and Necker. [185] Grimm, _Corr. Lit._, xi. 77. Diderot's candour, simplicity, happy bonhommie, and sincerity in real interests raised him habitually above the pettiness, the bustling malice, the vain self-consciousness, the personalities that infest all literary and social cliques. It is surprising at first that Diderot, who had all his life borne the sting of the gnats of Grub Street with decent composure, should have been so moved by Rousseau, or by meaner assailants, whom Rousseau himself would have rudely disclaimed. The explanation seems to lie in this fact of human character, that a man of Diderot's temperament, while entirely heedless of criticism directed against his opinions or his public position, is specially sensitive to innuendoes against his private benevolence and loyalty. An insult to the force of his understanding was indifferent to him, but an affront to one's _belle ame_ is beyond pardon. It was hard that a man who had prodigally thrown away the forces of his life for others should be charged with malignity of heart and an incapacity for friendship. This was the harder, because it was the moral fashion of that day to place friendliness, amiability, the desire to please and to serve, at the very head of all the virtues. The whole correspondence of the time is penetrated to an incomparable degree by a caressing spirit; it is sometimes too elaborate and far-fetched in expression, but it marks a vivid sociability, and even a true humanity, that softens and harmonises the sharpness of men's egotism.
