VIII. He took, however, his themes and subjects for declamation from the various topics of the day, which he learned from those who came to visit him. As soon as they left him he used to return to his study, and repeated aloud in the form of a speech all the news which he had heard, and made comments upon it. He also used to work up any conversations which he heard, into sentences and periods for his orations, and would alter, correct and paraphrase both his own remarks and those of his friends. This gave rise to the opinion that he was not really a man of ability, but that his power and skill as an orator was obtained by laborious study. A great proof of this was thought to be that Demosthenes seldom spoke on the spur of the moment, but often when he was present in the assembly and was called upon by the people to speak, he would remain silent unless he had prepared and meditated over his speech. Many of the other orators ridiculed him for this, and Pytheas in derision said that his arguments smelt of the lamp. To this Demosthenes made the bitter retort, "My lamp, Pytheas, sees very different work from yours." In conversation with others, however, he did not altogether deny the practice, but said that although he never spoke without having made notes, yet that he often spoke without having written down everything that he was going to say. He used to say that this careful preparation of his speeches showed that he was a true lover of the people, and felt a due reverence for them; while, on the contrary, to speak without caring how the people take one's words proves a man to be of an overbearing oligarchical disposition, who would use force rather than persuasion. Many writers allege, as a proof that Demosthenes dared not speak on the spur of the moment, that when he attacked Demades he was always immediately answered by him, but that he never so answered Demades.
