Priest Leaves Atheist Essay Denouncing Theistic Religion

Jean Meslier (French: [melje]; also Mellier;15 June 1664[1] – 17 June 1729), was a French Catholic priest (abbé) who was discovered, upon his death, to have written a book-length philosophical essay promotingatheism. Described by the author as his “testament” to his parishioners, the text denounces all religion. He denied that any spiritual value could be gained from suffering,and he used the deist’s argument from designagainst god, by showing the evils that he had permitted in this world.

His morality was irreproachable, and he often gave alms. He was otherwise extremely sober, as much in his words as in his relations with women. In his will he gave all he possessed, which was little, to his parishioners, and he asked that he be buried in his garden.
