The subjects of these writings were very various. Ostensibly, at least, they were by no means limited to matters of controversy. Some were successful tragedies, others were pieces of criticism, others were historical essays, others were frivolous short stories, or _vers de société_. But, in all of them, somewhere or other, the cloven hoof was bound to show itself at last. Whatever disguises he might assume, Voltaire in reality was always writing for his 'convent'; he was pressing forward, at every possible opportunity, the great movement against the old régime. His attack covers a wide ground. The abuses of the financial system, the defects in the administration of justice, the futility of the restraints upon trade--upon these and a hundred similar subjects he poured out an incessant torrent of gay, penetrating, frivolous and remorseless words. But there was one theme to which he was perpetually recurring, which forms the subject for his bitterest jests, and which, in fact, dominates the whole of his work, 'Écrasez l'infame!' was his constant exclamation; and the 'infamous thing' which he wished to see stamped underfoot was nothing less than religion. The extraordinary fury of his attack on religion has, in the eyes of many, imprinted an indelible stigma upon his name; but the true nature of his position in this matter has often been misunderstood, and deserves some examination.
