There is another device which the run of preachers often use to produce an effect; it is the square cap they wear on their heads. They take it off and put it on again with incredible speed. One of them attacked Voltaire and particularly Rousseau for the period's irreligion. He threw his cap into the centre of the pulpit and gave it the task of representing Jean-Jacques. In that role he harangued it, saying: Well, Genevan philosopher, what have you to say against my arguments? Then he would be silent for a few moments, as if waiting for an answer, and as the cap would say nothing in reply, he would put it back on his head and would finish the conversation with the words: Now that you are convinced, let us say no more about it.
