"You can make almost anything sound positive by adding the word "courage". Shall I demonstrate? The courage to lie to your lover. The courage to betray your comrades. The courage to be a lazy bum. The courage to admit defeat."
"Common sense" is a term used to make the prejudice (preconceived opinion that is not based on reason or actual experience) we acquire and in some cases develop, along the course of our lives sound acceptable.
