What is Reason?
Reason is the application of “pure logic”, empirical evidence, experiment, and skepticism to find truths, facts, and theories (AKA “critical thinking”).
Thomas Paine
Thomas Paine was one of history’s most important political propagandists in terms of human rights. His works inspired the American and French revolutions. See Thomas Paine’s Common Sense (pamphlet) 1776 and the Rights of Man 1792.
The Origin of the Political Terms Left and Right
The modern usage of the political terms left and right comes from the French Revolution of 1789 when supporters of the king stood to the president’s right, and supporters of the revolution to his left.
