These two opposed lines are in the first instance represented by Cain and Abel. With each child that comes into the world some fresh hope is brought; and the name of Cain points to the expectation of his parents that in him a fresh start would be made. Alas! as the boy grew they saw how vain such expectation was and how truly their nature had passed into his, and how no imparted experience of theirs, taught him from without, could countervail the strong propensities to evil which impelled him from within. They experienced that bitterest punishment which parents undergo, when they see their own defects and infirmities and evil passions repeated in their children and leading them astray as they once led themselves; when in those who are to perpetuate their name and remembrance on earth they see evidence that their faults also will be perpetuated; when in those whom they chiefly love they have a mirror ceaselessly held up to them forcing them to remember the follies and sins of their own youth. Certainly in the proud, self-willed, sullen Cain no redemption was to be found. Both sons own the necessity of labour. Man is no longer in the primitive condition, in which he had only to stretch out his hand when hungry, and satisfy his appetite. There are still some regions of the earth in which the trees shower fruit, nutritious and easily preserved, on men who shun labour. Were this the case throughout the world, the whole of life would be changed. Had we been created self-sufficing or in such conditions as involved no necessity of toil, nothing would be as it now is. It is the need of labour that implies occasional starvation and frequent poverty, and gives occasion to charity. It is the need of labour which involves commerce and thereby sows the seed of greed, worldliness, ambition, drudgery. The ultimate physical wants of men, food and clothes, are the motive of the greater part of all human activity. Trace to their causes the various industries of men, the wars, the great social movements, all that constitutes history, and you find that the bulk of all that is done upon earth is done because men must have food and wish to have it as good and with as little labour as possible. The broad facts of human life are in many respects humiliating.
