Love issues in honesty, truthfulness, purity, respect for life, justice, etc. It overarches and undergirds these. But it also stands alongside of these values. These children, born of love, stand in their own right and make their own specific claims. Situation ethics soft pedals on these demands of love and emphasises love alone in such a way that in the last resort these other values may be set aside with absolutely good conscience.
Love is the only intrinsic value.
Honesty, truthfulness, purity, justice, etc., have no intrinsic value. They have value only as they serve love. Particular values may be subjected to love when there is a tension in difficult situations but this can be done only with a relatively good conscience. If we go to war or endorse an abortion there can be only a relatively good conscience. The values that are subjected to love must continue to impose some kind of restraint and some uneasiness in our decided course of action.
