The Rainbow Is Such A Remarkable Phenomenon

The Rainbow Is Such A Remarkable Phenomenon Of Nature, And Its Cause Has Been So Meticulously Sought After By Inquiring Minds Throughout The Ages, That I Could Not Choose A More Appropriate Subject For Demonstrating How, With The Method I Am Using, We Can Arrive At Knowledge Not Possessed At All By Those Whose Writings Are Available To Us.

How Do We Know That Anything Really Exists, That Anything Is Really The Way It Seems Ot Us Through Our Senses?

He Who Hid Well, Lived Well.

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.

Everybody Thinks Himself So Well Supplied With Common Sense That Even Those Most Difficult To Please. . . Never Desire More Of It Than They Already Have.
