Knowledge Is Essential To Freedom.

The Sin That Now Rises To Memory As Your Bosom Sin, Let This First Of All Be Withstood And Mastered. Oppose It Instantly By A Detestation Of It, By A Firm Will To Conquer It, By Reflection, By Reason, And By Prayer.

The Worst Tyrants Are Those Which Establish Themselves In Our Own Breasts.

Be True To Your Own Highest Convictions.

I Call That Mind Free Which Protects Itself Against The Usurpations Of Society, And Which Does Not Cower To Human Opinion: Which Refuses To Be The Slave Or Tool Of The Many Or Of The Few, And Guards Its Empire Over Itself As Nobler Than The Empire Of The World.

In The Long Run, Truth Is Aided By Nothing So Much As By Opposition.
