Of most persons it may, perhaps, be said, without exaggeration, that they have a feeling of duty rather than a knowledge of it. When a certain situation presents itself they tend to act in a certain way, but they cannot clearly state the principle or rule which determines their action. The business of the moral teacher is to clarify, to classify, and to enrich the content of the conscience.
We cannot demonstrate the existence of disinterested motives. The sole fact that we demand unselfishness in action assures us that the standard of enlightened self-interest is false. And, indeed, if we consult the opinions of men where they are least likely to be warped by sophistry, we shall find that disinterestedness is the universal criterion by which moral worth is measured. If we suspect the motive we condemn the act.
LOVE AND MARRIAGE
Love is the expansion of two natures in such fashion that each includes the other, each is enriched by the other.
