Why the hell are you here?
A matter of conscience.
Really? said Locke. Yours? You keep alluding to its existence. Somehow I'm not convinced.

Prudence reproaches; conscience accuses.

Beware of knowing your virtues; you may lose them. Beware of knowing your vices; you may forgive them.

The one thing that doesn't abide by majority rule is a person's conscience.

I always tell people that my conscience, I can never compromise my conscience. If something is wrong, it is wrong. Conscience comprises a lot of things. They say every man has his or her own price. I believe I don’t have a price, I can never betray my conscience because someone has given me money. Never.

Conscience is the inner voice that warns us somebody may be looking.
