Thus we see what vein of thought was running through the graver and more active minds of Geneva about the time of Rousseau's visit. Whether it be true or not that the accepted belief of many of the preachers was a pure Deism, it is certain that the theory was fully launched among them, and that those who could not accept it were still pressed to refute it, and in refuting, to discuss. Rousseau's friendships were according to his own account almost entirely among the ministers of religion and the professors of the academy, precisely the sort of persons who would be most sure to familiarise him, in the course of frequent conversations, with the current religious ideas and the arguments by which they were opposed or upheld. We may picture the effect on his mind of the difference in tone and temper in these grave, candid, and careful men, and the tone of his Parisian friends in discussing the same high themes; how this difference would strengthen his repugnance, and corroborate his own inborn spirit of veneration; how he would here feel himself in his own world. For as wise men have noticed, it is not so much difference of opinion that stirs resentment in us, at least in great subjects where the difference is not trivial but profound, as difference in gravity of humour and manner of moral approach. He returned to Paris (Oct. 1754) warm with the resolution to give up his concerns there, and in the spring go back once and for all to the city of liberty and virtue, where men revered wisdom and reason instead of wasting life in the frivolities of literary dialectic.[245]
