regarded as an atheist. Although one overtly atheistic compendium known as the Theophrastus redivivus was published by an anonymous author in the seventeenth century, atheism was an epithet implying a lack of moral restraint. According to Geoffrey Blainey, the Reformation in Europe had paved the way for atheists by attacking the authority of the Catholic Church, which in turn "quietly inspired other thinkers to attack the authority of the new Protestant churches". Deism gained influence in France, Prussia and England, and proffered belief in a noninterventionist deity, but "while some deists were atheists in disguise, most were religious, and by today's standards would be called true believers". The scientific and mathematical discoveries of such as Copernicus, Newton and Descartes sketched a pattern of natural laws that lent weight to this new outlook. How dangerous it was to be accused of being an atheist at this time is illustrated by the examples of Étienne Dolet, who was strangled and burned in 1546. The English philosopher Thomas Hobbes (1588–1679) was also accused of atheism, but he denied it. His theism was unusual, in that he held god to be material. Even earlier, the British playwright and poet Christopher Marlowe (1563–1593) was accused of atheism when a tract denying the divinity of Christ was found in his home. Before he could finish defending himself against the charge, Marlowe was murdered. Giulio Cesare Vanini, also accused of being an atheist, was burned at the stake in 1619. Blainey wrote that the Dutch philosopher Baruch Spinoza was "probably the first well known 'semi-atheist' to announce himself in a Christian land in the modern era", although nowhere in his work does Spinoza argue against the existence of God. It is a widespread belief that Spinoza equated God with the material universe and so his beliefs have been categorized as Pantheist.Fraser, Alexander Campbell "Philosophy of Theism", William Blackwood and Sons, 1895, p. 163. Spinoza had been expelled from his synagogue for his protests against the teachings of its rabbis and for failing to attend Saturday services. He believed that God did not interfere in the running of the world, but rather that natural laws explained the workings of the universe. In 1661 he published his Short Treatise on God, but he was not a popular figure for the first century following his death: "An unbeliever was expected to be a rebel in almost everything and wicked in
