But Eucken has no patience with such theories. For him the oppositions and contradictions of life are too real and persistent. The antagonisms "stir us with disgust and indignation." Evil cannot be considered trivial, and must not be glossed over; it is in the world, and the more deeply we appreciate the fact the better it will be for the human soul. Man in his lower stages of development is just a child of nature, and his standards of life are those of the lower world. He seeks those things that satisfy the senses, he attempts the satiation of the lower cravings. In the realm of morals his standard is utility--that is good which helps him to obtain more pleasure and to avoid pain. In social life his conduct is dictated by custom--this is the highest appeal. The development of man along the lines of nature ends at this point--and if nothing more is to happen, then he must remain at a low level of development. Matter and mind cannot take him beyond--the mind as such only helps towards the further satisfaction of the lower demands of man. But there is something far greater in highly developed manhood than the petty and selfish. Man is capable of conceiving and adopting higher standards of morality than those of utility and pleasure, and it is the spiritual life that enables him to do this. It is the spiritual that frees the individual from the slavery of the sense world--from his selfishness and superficial interests--that teaches him to care less for the things of the flesh, and far more for the beautiful, the good, and the true, and that enables him to pursue high aims regardless of the fact that they may entail suffering and loss in other directions. This, then, is the "High" in the world; the natural life is the "Low." But what is the relation of the natural to the spiritual life? In the first place, the spiritual cannot be derived from the natural, inasmuch as the former is immensely superior to the latter, and that not merely in degree, but in its very essence. The spiritual is entirely on a higher plane of reality, and there cannot be transition from the natural to the spiritual world. The natural has its limitations, and beyond these cannot go. So far as the natural world is concerned man can never rise above seeking for pleasure, and making expediency and social approbation the standards of life, hence there is little wonder that those ethical teachers who make nature their basis, deny the possibility of action that is unselfish and free. "The Spiritual Life," however, as Eucken says, "has an independent origin, and evolves new powers and standards."
