In every living thing there is an element of continuous growth; in every aggregation of living things there is an element of continuous improvement. In the first instance, a vital actuality appears; whence, no one can tell. As the organism matures, a new germ is formed, which, as the parent stock decays, takes its place and becomes in like manner the parent of a successor. Thus even death is but the door to new forms of life. In the second instance, a body corporate appears, no less a vital actuality than the first; a social organism in which, notwithstanding ceaseless births and deaths, there is a living principle. For while individuals are born and die, families live; while families are born and die, species live; while species are born and die, organic being assumes new forms and features. Herein the all-pervading principle of life, while flitting, is nevertheless permanent, while transient is yet eternal. But above and independent of perpetual birth and death is this element of continuous growth, which, like a spirit, walks abroad and mingles in the affairs of men. "All our progress," says Emerson, "is an unfolding, like the vegetable bud. You have first an instinct; then an opinion, then a knowledge, as the plant has root bud and fruit." Under favorable conditions, and up to a certain point, stocks improve; by a law of natural selection the strongest and fittest survive, while the ill-favored and deformed perish; under conditions unfavorable to development, stocks remain stationary or deteriorate. Paradoxically, so far as we know, organs and organisms are no more perfect now than in the beginning; animal instincts are no keener, nor are their habitudes essentially changed. No one denies that stocks improve, for such improvement is perceptible and permanent; many deny that organisms improve, for if there be improvement it is imperceptible, and has thus far escaped proof. But, however this may be, it is palpable that the mind, and not the body, is the instrument and object of the progressional impulse. Man in the duality of his nature is brought under two distinct dominions; materially he is subject to the laws that govern matter, mentally to the laws that govern mind; physiologically he is perfectly made and non-progressive, psychologically he is embryonic and progressive. Between these internal and external forces, between moral and material activities there may be, in some instances, an apparent antagonism. The mind may be developed in excess and to the detriment of the body, and the body may be developed in excess and to the detriment of the mind. The animal man is a bundle of organs, with instincts implanted that set them in motion; man intellectual is a bundle of sentiments, with an implanted soul that keeps them effervescent; mankind in the mass, society,--we see the fermentations, we mark the transitions; is there, then, a soul in aggregated humanity as there is in individual humanity?
