Much has been made of the bargaining which he carried on with Frederick, as to the terms on which he would consent to go to Berlin. But then the Prussian king was not one with whom it was wise to be too nice in such affairs. He was the thriftiest of men, and as a king is a person who lives on other people’s money, such thrift was in his case the most princely of virtues. Haggling is not graceful, but it need not imply avarice in either of the parties to it. The truth is that there was in Voltaire a curious admixture of splendid generosity with virulent tenacity about half-pence. The famous quarrel with the President de Brosses about the fourteen cords of firewood is a worse affair. Voltaire, who leased Tourney from him, insisted that De Brosses had made him a present of the fourteen cords. De Brosses, no doubt truly, declared that he had only ordered the wood to be delivered on Voltaire’s account. On this despicable matter a long correspondence was carried on, in which Voltaire is seen at his very worst; insolent, undignified, low-minded, and untruthful.[84] The case happily stands alone in his biography. As a rule, he is a steady practitioner of the Aristotelian μεγαλοπρέπεια, or virtue of magnificent expenditure. The truly important feature of the life which Voltaire led at Cirey was its unremitting diligence. Like a Homeric goddess, the divine Emily poured a cloud round her hero. There is a sort of moral climate in a household, an impalpable, unseizable, indefinable set of influences, which predispose the inmates to industry and self-control, or else relax fibre and slacken purpose. At Cirey there was an almost monastic rule. Madame Grafigny says that though Voltaire felt himself bound by politeness to pay her a visit from time to time in her apartment, he usually avoided sitting down, apologetically protesting how frightful a thing is the quantity of time people waste in talking, and that waste of time is the most fatal kind of extravagance of which one can be guilty[85]. He seems to have usually passed the whole day at his desk, or in making physical experiments in his chamber. The only occasion on which people met was at the supper at nine in the evening. Until then the privacy of the chamber alike of the hostess, who was analysing Leibnitz or translating Newton, and of the unofficial host, who was compiling material for the Siècle de Louis XIV., or polishing and repolishing Mahomet, or investigating the circumstances of the propagation of fire, was sacredly inviolable.
