The Renaissance and Reformation eras witnessed a resurgence in religious fervor, as evidenced by the proliferation of new religious orders, confraternities, and popular devotions in the Catholic world, and the appearance of increasingly austere Protestant sects such as the Calvinists. This era of interconfessional rivalry permitted an even wider scope of theological and philosophical speculation, much of which would later be used to advance a religiously skeptical world-view.

Theoretical, or contemplative, atheism explicitly posits arguments against the existence of gods, responding to common theistic arguments such as the argument from design or Pascal’s wager. The theoretical reasons for rejecting gods assume various psychological, sociological, metaphysical, and epistemological forms.

Socrates (ca 470–399)

Socrates firmly believed that, before anyone can understand the world, they first need to understand themselves. And the only way to accomplish that is with rational thought. Socrates did not publish or write any of his thoughts, but he was constantly in discussion with others. He would usually start by asking a (seemingly answerable) question, to which the other would give an answer. Socrates would then continue to ask questions until all conflicts were resolved, or until the other could do nothing else but admit he didn’t know the answer (which was what most of his discussions ended with). Socrates did not claim to know the answers, but that did not take away the ability to critically and rationally approach problems.

Metaphysical atheism is based on metaphysical monism—the view that reality is homogeneous and indivisible. Absolute metaphysical atheists subscribe to some form of physicalism, hence they explicitly deny the existence of non-physical beings. Relative metaphysical atheists maintain an implicit denial of a particular concept of God based on the incongruity between their individual philosophies and attributes commonly applied to God, such as transcendence, a personal aspect, or unity. Examples of relative metaphysical atheism include pantheism, panentheism, and deism.

In epistemology and in its broadest sense, rationalism is “any view appealing to reason as a source of knowledge or justification” (Lacey 286). In more technical terms it is a method or a theory “in which the criterion of truth is not sensory but intellectual and deductive” (Bourke 263). Different degrees of emphasis on this method or theory lead to a range of rationalist standpoints, from the moderate position “that reason has precedence over other ways of acquiring knowledge” to the radical position that reason is “the unique path to knowledge” (Audi 771).
