The "moral sense" of which positive science speaks is to a great extent the sense of sympathy with our fellows, the comprehension of their sorrows, the sentiment of justice: the lack of these sentiments convulses normal life. We cannot become moral by committing codes and their applications to memory, for memory might fail us a thousand times, and the slightest passion might overcome us; criminals, in fact, even when they are most astute and wary students of codes, often violate them; while normal persons, although entirely ignorant of the laws, never transgress them, owing to "an internal sense which guides them." Positive science includes in the term "moral sense" something complex which is, at the same time, sensibility to public opinion, to law, and to religion; and multiplying it thus, it does not clearly define in what "moral sense" consists. We talk of it intuitively; each one has within himself something that "responds" to the appellation; and by this internal response he must understand and decide in what this "moral sense" consists. But religion is simple and precise: it calls this internal sense which lies at the root of life, Love. Social laws do not enter into this any more than does the entire universe. Love is the contact between the soul and God; and when this exists, all the rest is vanity. Good springs therefrom naturally, as sunbeams radiate from the sun. Creation itself has been given in charge of this wellspring of love, and it is love which maintains it, as the contribution of the creature to the provident forces of nature.
