Rabbi Maimonides: "It is written: 'The wicked will be destroyed and there will not rest anything of him.'"

Ecclesiastes: "Men die as the beasts and their fate is the same. They have all one breath."

The soul was at first conceived in very material ways. The idealistic movement in Greek philosophy is responsible for the concept of an immaterial substance. "Under the influence of mystical, religious motives the soul becomes more and more non-spatial and intangible. The words used are negative and abstract. It is generally supposed that Plotinus was the first to describe the soul as an immaterial substance. But this immaterial substance must somehow be brought into relation with the physical body." It was this situation which gave rise to the soul-body problem in philosophy, a problem which has gradually changed into the mind-body problem. This transformation of the puzzle is significant. The very terms have changed and have become more concrete and empirical. A quotation from William James—a man who had no bias against theology—will bring out the essential reasons for this significant change of terms: "Yet it is not for idle or fantastical reasons that the notion of the substantial soul, so freely used by common men and the more popular philosophies, has fallen upon such evil days, and has no prestige in the eyes of critical thinkers. It only shares the fate of other unrepresentable substances and principles. They are without exception all so barren that to sincere inquirers they appear as little more than names masquerading."

I am inclined to believe that, to most people, to-day, the soul means no more than the personality, and the conviction that this cannot be reduced to the body. It stands for consciousness and character as somehow rooted in something permanent. Plato's idea of the soul as a simple, indestructible substance awakens hardly an echo in their minds—and why should it? Something which guarantees and makes possible the continued existence of their conscious self after the death of the body is the association which is uppermost. Educated people, at least, have outgrown the ghost-soul of primitive times and have put their hope in the inability of the philosophic scientist to explain life and consciousness without appeal to agencies which are inexplicable on naturalistic terms. But it is obvious that such a basis is overhung by an ever-threatening danger. If the mind-body problem were solved in a concrete, empirical way, what then?

It has been customary to examine the question of immortality from three angles which may be called, respectively, the empirical, the ethical and the philosophical. The more recent drift of philosophy toward realism has tended to bring the first and the third methods of approach closer together. It has increasingly been felt that philosophy coöperates with the special sciences and is inseparable from them. The ethical argument in favor of immortality is oftener found in poetry than in serious books on ethics. It cannot be said to have sufficient force to swing the balance established by science and a realistic philosophy in touch with science.

The empirical status of immortality can best be brought out by a glance at the facts of abnormal psychology. In olden days, as we have seen, insanity was explained as the disturbing effect of a demon. To-day, experiment and careful observation have proven that it is due to a functional disorder of the brain. That, whenever there is a disorder of the mind, there is some corresponding anatomical or physiological flaw in the brain has become a commonplace of modern medicine and psychology. In fact, insanity is defined as a "symptom of disease of the brain inducing disordered mental symptoms." A multitude of experiences point to the very intimate connection between the brain and consciousness. Careful observation of clinical cases has, for example, shown that a lesion in the visual center of the brain, that is, the part of the brain to which the fibers of the optic nerve run, induces the disappearance of both sight and visual imagery. Psychology and physiology have been busily engaged in discovering these correlations. So extended are they that the suggestion that consciousness is inseparable from the brain forces itself home ever more obstinately. Mental capacity runs parallel with the finer development of the brain. Is not, therefore, the very meaning of mental capacity connected with the needs and activities of the organism? But the case is still stronger when we note what happens to an individual when something goes wrong with the brain. Can this poor lunatic, who has dropped from the high level of educated manhood to a condition more helpless than that of an animal, just because of a relatively slight disintegration of the cortex, be expected to recover his intellect by means of its total disintegration? Can it be denied that the burden of proof rests on those who assert immortality?

The so-called ethical argument for immortality is associated with the name of Immanuel Kant. Kant's philosophy was agnostic, and it was this agnosticism which made his use of the ethical argument possible. If you can't make any assured theoretical statement about the nature of the self, you can allow demands, which you regard as ethical and primary, to dictate your ultimate beliefs. It cannot be denied that Kant's argument savors of the popular notion that the virtuous must be rewarded. At its highest, the ethical argument signifies a demand for a future life in order to carry out that development of character which the brief span of earthly life is not equal to. It is this argument which runs through Browning. What shall we say of it?

There are both factual and theoretical objections to the ethical argument for immortality. The more we know about habit, the more we realize that character is pretty well "set" by middle life. The creative period of human life ends all too soon. Character is not an abstract possession separable from human tasks and needs. It is not like a work of art which can be polished and re-polished. But, when all is said and done, ethics must abide by the facts of the case. Take character abstractly enough and apart from its human and organic setting, and the dream of continuous perfecting may have meaning; but so would the dream of continuous intellectual advance. Yet the scholar knows all too well the judgment passed by the coming generation upon the older one: "They can't adjust themselves to this new point of view." Would progress come if the generations did not pass?

The philosophical aspect of the question can be touched upon only briefly and in an untechnical way. The basic problem may be put in this way: Can human personality be included in nature in a theoretically satisfactory way? It has been customary to stress the difficulties which confront such an attempt and to be silent in regard to the problems which the separation of body and personality has always found facing it. Yet I think that few philosophers would deny that it is the very irrationality of the traditional dualism which makes a living monism of mind and body so desirable and so urgently sought after.
