There Is Nothing Higher Than Reason.

Nature Even In Chaos Cannot Proceed Otherwise Than Regularly And According To Order.

So Act That Anything You Do May Become Universal Law.

In Man (as The Only Rational Creature On Earth) Those Natural Capacities Which Are Directed To The Use Of His Reason Are To Be Fully Developed Only In The Race, Not In The Individual.

There Is No Virtue In Penance And Fasting Which Waste The Body; They Are Only Fanatical And Monkish.

There Can Be No Doubt That All Our Knowledge Begins With Experience.
