April 9, 1347 – English friar William of Ockham dies in what is now Munich, Germany. He is best known by his namesake Ockham’s Razor (also Occam’s Razor), the “law of parsimony” that suggests that the hypothesis with the fewest assumptionsÂ is usually the best. Although Ockham was a devout Christian and never expressed this law in so many words, Ockham’s Razor has become a touchstone for scientists and skeptics.

In fact, the great religious ages were notable for their indifference to human rightsâ€¦ Human rights is not a religious idea. It is a secular idea, the product of the last four centuries of Western historyâ€¦. The basic human rights documents â€“ the American Declaration of Independence and the French Declaration of the Rights of Man â€“ were written by political, not religious, leaders.”
