Man Must Suffer To Be Wise.

O Wretched Man, Wretched Not Just Because Of What You Are, But Also Because You Do Not Know How Wretched You Are!

There Is, I Know Not How, A Certain Presage, As It Were, Of A Future Existence; And This Takes The Deepest Root, And Is Most Discoverable, In The Greatest Geniuses And Most Exalted Souls.

If Our Lives Are Endangered By Plots Or Violence Or Armed Robbers Or Enemies, Any And Every Method Of Protecting Ourselves Is Morally Right.

That Man Is Guilty Of Impertinence Who Considers Not The Circumstances Of Time, Or Engrosses The Conversation, Or Makes Himself The Subject Of His Discourse, Or Pays No Regard To The Company He Is In.

Before Beginning, Prepare Carefully.
