Freethought Day

Every free citizen has the right to express their thoughts on political, educational, and scientific matters, no matter how others may criticize free thinkers. Throughout history, it is these individuals who have changed the world—among them are Albert Einstein, Leonardo da Vinci, Galileo Galilei, Isaac Newton, and Jesus.

History

Freethought Day is celebrated on October 12, the date when Governor William Phips of colonial Massachusetts wrote a letter to British authorities, raising concerns about the Salem witch trials. Phips argued that the evidence in the trials was merely fantasy and prejudice, not fact. In 1997, the Freethinking Society, the American Humanist Association, and the Secular Coalition for America established Freethought Day to commemorate the ongoing struggle for free expression since the Salem witch trials.

Interesting Facts

Here are a few facts about free-thinking individuals and their impact:

• Between 335 and 323 BC, Aristotle wrote many of his philosophical works.
• In 1633, Galileo Galilei was tried by the Roman Inquisition for his free-thinking ideas about the universe.
• In 1923, Albert Einstein was awarded the Nobel Prize in Physics for discovering the photoelectric effect.

How to Take Part

On Freethought Day, explore and learn about the perspectives of modern opinion leaders without rushing to judgment. Reflect on how thinkers from the past, often condemned for their ideas, are now celebrated. Consider reading historical accounts, such as those related to the Salem witch trials, or organizing a discussion event to honor free thought. Most importantly, express your own ideas openly and respectfully.
