Conquer Yourself Rather Than The World.

These Long Chains Of Perfectly Simple And Easy Reasonings By Means Of Which Geometers Are Accustomed To Carry Out Their Most Difficult Demonstrations Had Led Me To Fancy That Everything That Can Fall Under Human Knowledge Forms A Similar Sequence; And That So Long As We Avoid Accepting As True What Is Not So, And Always Preserve The Right Order Of Deduction Of One Thing From Another, There Can Be Nothing Too Remote To Be Reached In The End, Or To Well Hidden To Be Discovered.

For How Do We Know That The Thoughts Which Occur In Dreaming Are False Rather Than Those Others Which We Experience When Awake, Since The Former Are Often Not Less Vivid And Distinct Than The Latter?

Hence Reason Also Demands That, Since Our Thoughts Cannot All Be True Because We Are Not Wholly Perfect, What Truth They Do Possess Must Inevitably Be Found In The Thoughts We Have When Awake, Rather Than In Our Dreams.

Nothing Is More Fairly Distributed Than Common Sense: No One Thinks He Needs More Of It Than He Already Has.

He Who Hid Well, Lived Well.
