For Me Writing Biographies Is Impossible, Unless

To His Sister-in-law: What A Contrast Between Us! You Live A Warm And Glowing Life, Surrounded By Loved Ones Whom You Care For And Who Care For You; You Are Anchored In Contentment. I Drift About Without Rudder Or Compass, A Wreck On The Sea Of Life; I Have No Memories To Cheer Me, No Pleasant Illusions Of The Future To Comfort Me, Or About Me To Satisfy My Vanity. I Have No Family To Furnish The Only Kind Of Survival That Concerns Us, No Friends For The Wholesome Development Of My Affections, Or Enemies For My Malice.

I Am A Misanthrope Yet Utterly Benevolent.

If I Have A Thousand Ideas And Only One Turns Out To Be Good, I Am Satisfied.

The Truthful Man Is Usually A Liar.
