Religious skepticism in the context of Aponia

In religion, faith is "belief in God or in the doctrines or teachings of religion".

Religious people often think of faith as confidence based on a perceived degree of warrant, or evidence, while others who are more skeptical of religion tend to think of faith as belief without evidence.

Epicureanism is a system of philosophy founded in 307 BCE and based upon the teachings of Epicurus, an ancient Greek philosopher. Epicurus was an atomist and materialist, following in the steps of Democritus. His materialism led him to religious skepticism and a general attack on superstition and divine intervention. Epicureanism was originally a challenge to Platonism, and its main opponent later became Stoicism. It is a form of hedonism insofar as it declares pleasure to be its sole intrinsic goal. However, the concept that the absence of pain and fear constitutes the greatest pleasure, and its advocacy of a simple life, make it very different from hedonism as colloquially understood.

Following the Cyrenaic philosopher Aristippus, Epicurus believed that the greatest good was to seek modest, sustainable pleasure in the form of a state of ataraxia (tranquility and freedom from fear) and aponia (the absence of bodily pain) through knowledge of the workings of the world and limiting desires. Correspondingly, Epicurus and his followers generally withdrew from politics because it could lead to frustrations and ambitions that would conflict with their pursuit of virtue and peace of mind.

Irreligion is the absence or rejection of religious beliefs or practices. It encompasses a wide range of viewpoints drawn from various philosophical and intellectual perspectives, including atheism, agnosticism, religious skepticism, rationalism, secularism, and non-religious spirituality. These perspectives can vary, with individuals who identify as irreligious holding diverse beliefs about religion and its role in their lives.

Relatively little scholarly research was published on irreligion until around the year 2010.

George Henry Lewes (/ˈluːɪs/ ; 18 April 1817 – 30 November 1878) was an English philosopher and critic of literature and theatre. He was also an amateur physiologist. American feminist Margaret Fuller called Lewes a "witty, French, flippant sort of man". He became part of the mid-Victorian ferment of ideas which encouraged discussion of Darwinism, positivism, and religious skepticism. However, he is perhaps best known today for having openly lived with Mary Ann Evans, who wrote under the pen name George Eliot, as soulmates whose lives and writings were enriched by their relationship, though they never married each other.
