“I often cannot believe the things I do.”

“Man often becomes what he believes himself to be. If I keep on saying to myself that I cannot do a certain thing, it is possible that I may end by really becoming incapable of doing it. On the contrary, if I have the belief that I can do it, I shall surely acquire the capacity to do it even if I may not have it at the beginning.”

“Because I do not accept the hand of God; I do not believe in divine intervention or predestination. I cannot believe that our paths are pre-chosen and that our lives have no will. That there is no such thing as choice.”

“I want you to believe...to believe in things that you cannot.”

“I can do things you cannot, you can do things I cannot; together we can do great things.”

“A house divided against itself cannot stand." I believe this government cannot endure, permanently half slave and half free. I do not expect the Union to be dissolved — I do not expect the house to fall — but I do expect it will cease to be divided. It will become all one thing or all the other.”
