Unselfish man has in the past been woefully handicapped. Fifty years ago he could not have said to his wife, as he can now, “Do no cooking today, but buy some baked beans or boiled ham for supper and you go to the art exhibition.” Fifty years ago there was little object in trying to relieve his wife of her household cares, for then there was little else upon which she could profitably spend her time. Now, when he wishes to be unselfish, his opportunities for accomplishing something worth while thereby are great. Of course he is always encountering his wife’s desire to be unselfish also, and to stay at home and cook the food he likes and otherwise to provide for his comfort, but the two must settle that between themselves, with due regard on the part of each for preserving the proper balance in the life of the other. In this struggle the greater possibilities in the way of development and increase of life lie with man. To woman it is given to accept a self-sacrifice which nature has mapped out for her by specializing her for childbearing and which society has mapped out for her by specializing her for housekeeping. To man it is given to map out for himself a new path into unselfishness and to secure the expansion of powers that comes from pioneering. Nor is this higher affection merely its own reward. To the increase of life brought by love is added increase in all other directions, presupposing always ideas and ideals in woman as well as in man. With leisure created by man’s unselfishness, woman can study and secure mental development which makes her a wiser conserver of man’s health, a better comrade in his leisure, and a more intelligent helper in his labors. To use the phraseology of our definition of life, she can better assist him to secure health, to enjoy the pleasures of the senses, to learn, and to do. He wishes health. There was a time when his work demanded life-giving, muscular exercise in the fresh air, when his house was so loosely built that it was inevitably well ventilated, when he lived so far from his neighbors that there was no danger of catching their diseases either through contamination of water supply or otherwise, when his food passed directly from garden to table, fresh and unadulterated. Then health came almost unbidden. His wife, though she could help him in many other ways, could do little for his health except to cook his food properly. Later, things changed. He moved into the town and his neighbor’s sewage percolated into his well. His house was tightly built and admitted little air through the cracks. His work became sedentary and kept him indoors most of the time. His food was brought to him from the four corners of the earth, passing through many hands on the way, and was liable to deterioration and adulteration.
