He Who Pretends To Look Upon Death

I Have Never Thought, For My Part, That Man's Freedom Consists In His Being Able To Do Whatever He Wills, But That He Should Not, By Any Human Power, Be Forced To Do What Is Against His Will.

Childhood Is The Sleep Of Reason. [fr., L'enfance Est Le Sommeil De La Raison.]

Teach Your Scholar To Observe The Phenomena Of Nature; You Will Soon Rouse His Curiosity, But If You Would Have It Grow, Do Not Be In Too Great A Hurry To Satisfy This Curiosity. Put The Problems Before Him And Let Him Solve Them Himself. Let Him Know Nothing Because You Have Told Him, But Because He Has Learnt It For Himself. Let Him Not Be Taught Science, Let Him Discover It. If Ever You Substitute Authority For Reason He Will Cease To Reason; He Will Be A Mere Plaything Of Other People's Thoughts.

It Is Too Difficult To Think Nobly When One Thinks Only Of Earning A Living.

It Is In Man's Heart That The Life Of Nature's Spectacle Exists; To See It, One Must Feel It.
