Atheist Day Hero

Bertrand Russell

Bertrand Russell (1872–1970) was a towering British philosopher, logician, mathematician, and social critic, widely regarded as one of the most important thinkers of the 20th century. A prominent atheist and humanist, he advocated for reason and secular ethics throughout his prolific career. Russell was awarded the Nobel Prize in Literature in 1950 in recognition of his varied and significant writings in which he championed humanitarian ideals and freedom of thought. His essay 'Why I Am Not a Christian' remains a foundational text in atheist literature.

History of Atheist Day

The concept of atheism is said to be as old as religion itself. There have been records and writings suggesting that even in Judaism during 550 B.C. Some people did not believe in the existence of Gods. There has also been evidence suggesting the same in Christianity and Islam later on.

Lokayata was a school in India during the sixth century B.C. which was openly atheistic.
However, in those times, being an atheist was frowned upon. Being called an atheist was taken as an insult. Even stories suggest that people with such beliefs were executed and treated as outcasts in societies.

In the Middle Ages, many freethinkers like Al-Ma’arri in Persia and Nicholas of Cusa from ancient Germany further spread the concept of atheism. During the Renaissance, Leonardo Da Vinci and Niccolò Machiavelli challenged the views of the Church and religion.

With communism rising in Eastern Europe and Asia, the concept of atheism became more acceptable. Though the term atheist was simply used as an umbrella term to refer to someone who didn’t believe in God, there existed different levels of atheism in society.

Some people were skeptical about beliefs in general. Some didn’t believe in a God but felt that it could be tolerated, and then there were some like the ‘New Atheists’ who believed in not just tolerating it but rather opposing it. Agnosticism was a concept that stemmed from this belief.

It suggested that the existence or non-existence of God cannot be proved.
