Thenceforward he never faltered on his path. It is his peculiar excellence to be an original and innovating thinker not only in philosophy but in psychology, in æsthetics, in ethics, in dramatic art; and his endless and miscellaneous labours in the Encyclopédie, of which he was the most loyal and devoted producer, represent an extraordinary range of interests. He suffered from his position as a hack writer and as a forced dissembler in his articles on religious matters; and there is probably a very real connection between his compulsory insincerities [1117] in the Encyclopédie--to say nothing of the official prosecution of that and of others of his works--and his misdeeds in the way of indecent fiction. When organized society is made to figure as the heartless enemy of thinking men, it is no great wonder if they are careless at times about the effect of their writings on society. But it stands to his lasting honour that his sufferings at the hands of priests, printers, and parlements never soured his natural goodness of heart. [1118] Having in his youth known a day's unrelieved hunger, he made a vow that he would never refuse help to any human being; and, says his daughter, no vow was ever more faithfully kept. No one in trouble was ever turned away from his door; and even his enemies were helped when they were base enough to beg of him. It seems no exaggeration to say that the bulk of his life was given to helping other people; and the indirect effect of his work, which is rather intellectually disinterested than didactic, is no less liberative and humanitarian. "To do good, and to find truth," were his mottoes for life.
