In the sphere of action, a right thought is one ruled by the will of God, and intentions are holy when directed singlemindedly toward him. In a word, we could see clearly through any action of ours, or into our entire lives, if we had a simple eye. A simple eye is an eye, and it is simple. This means that we see by right thinking what is to be done, and by our good intention we carry it out with simple honesty, because deceitful action is wrong. Right thinking does not permit mistakes; a good intention rules out pretense. This then is true discernment, a combination of right thinking and good intention. Therefore, we must do all our actions in the light of discernment as if in God and in his presence.
Baldwin of Canterbury
from The Liturgy of the Hours, vol. III, p. 312.
