Thought of the Day — The Angelic Doctor on Pride

There are two sides to every sin: the turning of the will toward fleeting satisfaction and the turning away from everlasting value. As regards to the first, the principle of all sins can be called lust--lust in its most general sense, namely, the unbridled desire for one's own pleasure. As regards to the second, the principle is pride-- pride in its general sense, the lack of submission to God.

-- St. Thomas Aquinas
