I Believe In God And In Nature

I Have Never Looked At Foreign Countries Or Gone There But With The Purpose Of Getting To Know The General Human Qualities That Are Spread All Over The Earth In Very Different Forms, And Then To Find These Qualities Again In My Own Country And To Recognize And To Further Them.

Common Sense Is The Genius Of Humanity.

When I Err Every One Can See It, But Not When I Lie. [ger., Wenn Ich Irre Kann Es Jeder Bemerken; Wenn Ich Luge, Nicht.]

Without My Attempts In Natural Science, I Should Never Have Learned To Know Mankind Such As It Is. In Nothing Else Can We So Closely Approach Pure Contemplation And Thought, So Closely Observe The Errors Of The Senses And Of The Understanding, The Weak And Strong Points Of Character.

Behavior Is The Mirror In Which Everyone Shows Their Image.
