National Freethought Day Hero

Voltaire

François-Marie Arouet, better known by his pen name Voltaire, was an 18th-century French Enlightenment writer, historian, and philosopher. A fierce advocate of civil liberties, including freedom of religion and free speech, he was a prominent figure who championed reason and challenged the authority of the church and state. His satirical works and philosophical treatises, such as 'Candide,' remain cornerstones of freethought.

History of National Freethought Day

There’s a reason why National Freethought Day is celebrated on October 12: On this day in 1692, William Phips, the then governor of colonial Massachusetts, wrote a letter to the British monarchs expressing concern about how the Salem Witch Trials were heard and prosecuted according to spectral evidence. He complained that the entire evidence upon which judgment was executed was someone’s beliefs and dreams. In the Salem Witch Trials, almost all of the evidence were assumptions that a person was involved in consorting with devils; there was no definite proof. William Phips, therefore, following mass protests and agitation, stopped the Salem Witch Trials.

In 1994 organizations such as Freethought Society, American Humanist Association, and Secular Coalition For America initiated the celebrations for Freethought. And although the Salem Witch Trials were abolished in 1693, persecution for free-thinking continues to date. History bears witness that those who, instead of following society’s norm and convention, chose a different (often eccentric) path were either greatly rewarded or severely opposed and ostracized. That one’s ideas contradict established norms does not make one any less deserving to be heard. If freedom of thought were outlawed, we would have been denied some of the most brilliant discoveries, inventions, and creations that humankind has achieved. National Freethought Day celebration began in 1994, but it took another four years before it became popular and celebrated all over the country.
