By a lie a man throws away, and as it were, annihilates his dignity as a man. - Immanuel Kant

Act only according to that maxim whereby you can at the same time will that it should become a universal law.

...[T]he sublimity and intrinsic dignity of the command in duty are so much the more evident, the less the subjective impulses favor it and the more they oppose it, without being able in the slightest degree to weaken the obligation of the law or to diminish its validity.

Art is purposiveness without purpose.
