Nothing Comes Out Of Nothing.

But Possibly I Am Something More Than I Suppose Myself To Be.

Because Reason...is The Only Thing That Makes Us Men, And Distinguishes Us From The Beasts, I Would Prefer To Believe That It Exists, In Its Entirety, In Each Of Us.

I Hope That Posterity Will Judge Me Kindly, Not Only As To The Things Which I Have Explained, But Also To Those Which I Have Intentionally Omitted So As To Leave To Others The Pleasure Of Discovery.

Every Man Is Indeed Bound To Do What He Can To Promote The Good Of Others, And A Man Who Is Of No Use To Anyone Is Strictly Worthless.

Everything Is Self-evident.
