"Contradictions do not exist. Whenever you think you are facing a contradiction, check your premises. You will find that one of them is wrong."

"A desire presupposes the possibility of action to achieve it; action presupposes a motive from which to act."

"The man who is wrong and knows it, is not as dangerous as the man who is wrong and believes he is right."

"There are no contradictions in reality. Contradictions exist only in the mind, in the mind of a man who makes a mistake."
