Charles Malik

"There is truth, and there is falsehood. There is good, and there is evil. There is happiness, and there is misery. There is that which ennobles, and there is that which demeans. There is that which puts you in harmony with yourself, with others, with the universe, and with God, and there is that which alienates you from yourself, and from the world, and from God. These things are different and separate and totally distinguishable from one another."

from C.S. Lewis for the Third Millennium by Peter Kreeft
