“A house divided cannot stand.”

“He whose wisdom surpasses that of all philosophers, has declared that 'a house divided against itself cannot stand”

“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.”

“Stand with anyone that is right; stand with him while he is right and part with him when he goes wrong.”

“You cannot escape the responsibility of tomorrow by evading it today.”

“You cannot have the right to do what is wrong!”

“Be sure you put your feet in the right place, then stand firm.”
