We See Only What We Know.

In The Realm Of Ideas Everything Depends On Enthusiasm... In The Real World All Rests On Perseverance.

Whoever, In Middle Age, Attempts To Realize The Wishes And Hopes Of His Early Youth, Invariably Deceives Himself. Each Ten Years Of A Man's Life Has Its Own Fortunes, Its Own Hopes, Its Own Desires.

Ye Great Teachers: Listen To What You Say!

All Men Would Be Masters Of Others, And No Man Is Lord Of Himself.

He Who Wishes To Exert A Useful Influence Must Be Careful To Insult Nothing. Let Him Not Be Troubled By What Seems Absurd, But Concentrate His Energies To The Creation Of What Is Good. He Must Not Demolish, But Build. He Must Raise Temples Where Mankind May Come And Partake Of The Purest Pleasure.
