"To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection."

“In any ethical situation, the thing you want least to do is probably the right action.”

“To stand on the firing parapet and expose yourself to danger; to stand and fight a thousand miles from home when you’re all alone and outnumbered and probably beaten; to spit on your hands and lower the pike; to stand fast over the body of Leonidas the King; to be rear guard at Kunu-Ri; to stand and be still to the Birkenhead Drill; these are not rational acts.
