Conscience is the inner voice which warns us that someone might be looking.

Your conscience never stops you from doing anything. It just stops you from enjoying it.

No snowflake in an avalanche ever feels responsible.

"There is only one way to achieve happiness on this terrestrial ball, and that is to have either a clear conscience or none at all."

To say of an act done, "My conscience is quite clear", sounds smug and satisfactory. It does not by any means follow that the speaker's conscience ought to be clear. It may simply show that [it] is sadly unenlightened.

A man can do only what a man can do. But if he does that each day he can sleep at night and do it again the next day.

He that respects himself is safe from others; he wears a coat of mail that none can pierce.

On some positions, Cowardice asks the question, "Is it safe?" Expediency asks the question, "Is it politic?" And Vanity comes along and asks the question, "Is it popular?" But Conscience asks the question, "Is it right?" And there comes a time when one must take a position that is neither safe, nor politic, nor popular, but he must do it because Conscience tells him it is right.
