a civilized taste for the elite—an educational approach that reached the contemporary era. Enlightenment During the Age of Enlightenment, humanistic ideas resurfaced, this time further from religion and classical literature. Science and intellectualism advanced, and humanists argued that rationality could replace deism as the means with which to understand the world. Humanistic values, such as tolerance and opposition to slavery, started to take shape. New philosophical, social, and political ideas appeared. Some thinkers rejected theism outright; and atheism, deism, and hostility to organized religion were formed. During the Enlightenment, Baruch Spinoza redefined God as signifying the totality of nature; Spinoza was accused of atheism but remained silent on the matter. Naturalism was also advanced by prominent Encyclopédistes. Baron d'Holbach wrote the polemic System of Nature, claiming that religion was built on fear and had helped tyrants throughout history. Diderot and Helvetius combined their materialism with sharp, political critique. Also during the Enlightenment, the abstract conception of humanity started forming—a critical juncture for the construction of humanist philosophy. Previous appeals to "men" now shifted toward "man"; this is evident in political documents like The Social Contract (1762) of Rousseau, in which he says "Man is born free, but is everywhere in chains". Likewise, Thomas Paine's Rights of Man uses the singular form of the word, revealing a universal conception of "man". In parallel, Baconian empiricism—though not humanism per se—led to Thomas Hobbes's materialism. While there is a widely-held belief that the birth of humanism was solely a European affair, scholar J. Brent Crosson argues that intellectual thought from Africa and Asia significantly contributed as well. He also notes that during enlightenment, the universal man did not encompass all humans but was shaped by gender and race. According to Crosson, the shift from man to human started during enlightenment and is still ongoing. Crosson also argues that enlightenment, especially in Britain, produced not only a notion of universal man, but also gave birth to pseudoscientific ideas, such as those about differences between races, that shaped European history. He gives as example the paradigm of Africa, which contributed to knowledge until the Renaissance but was disregarded afterwards. From Darwin to current era French philosopher Auguste Comte (1798–1857) introduced the idea—which is sometimes attributed to Thomas Paine—of a "religion of humanity". This was intended to be an atheist cult based on some humanistic tenets, and had some prominent members but soon declined. It was
