What happened to the Revolutionary War heroes that weren't lucky enough to eventually get elected to the office of President of the United States? Obviously, they can't be celebrated on President's Day. The answer: If they're lucky, the got their very own holiday, like Thomas Paine.
On January 29th, Americans (very few of them) celebrate a holiday dedicated to the philosopher who authored the famous "Common Sense" pamphlet -- Thomas Paine Day, also known as Freethinkers Day: "Freethinkers Day, also known as Thomas Paine Day, is an opportunity to promote appreciation of free thought thought the life and works of Thomas Paine. Free thought supports reason over faith, and rejects arbitrary authority."
Aside from lending his pen to the struggle for independence, Paine was also a soldier in the revolutionary army and became secretary of the Congressional Committee on Foreign Affairs ... until his free-thinking eventually got him expelled.
Since the holiday is not widely celebrated (I'd never even heard of it before), the way to properly celebrate Freethinker's Day is limited only by your imagination, ironically. And though it feels strangely contradictory to suggest ways to celebrate Freethinker's Day, plenty of people have done it. Thomas Paine Day is best enjoyed by visiting Thomas Paine monuments, like Paine's New York cottage, and pondering (freely) over some of the thinker's most heralded works.
