Ingratitude Is The Essence Of Vileness.

All False Art, All Vain Wisdom, Lasts Its Time But Finally Destroys Itself, And Its Highest Culture Is Also The Epoch Of Its Decay.

Man's Duty Is To Improve Himself; To Cultivate His Mind; And, When He Finds Himself Going Astray, To Bring The Moral Law To Bear Upon Himself.

Our Intellect Does Not Draw Its Laws From Nature, But It Imposes Its Laws Upon Nature.

If Education Is To Develop Human Nature So That It May Attain The Object Of Its Being, It Must Involve The Exercise Of Judgment.

Ingratitude Is The Essence Of Vileness.
