The Case for Life After Death
Can you prove life after death?
Whenever we argue about whether a thing can be proved, we should distinguish five different questions about that thing:
If life after death cannot be proved scientifically, is it then intellectually irresponsible to accept it? Only if you assume that it is intellectually irresponsible to accept anything that cannot be proved scientifically. But that premise is self-contradictory (and therefore intellectually irresponsible)! You cannot scientifically prove that the only acceptable proofs are scientific proofs. You cannot prove logically or empirically that only logical or empirical proofs are acceptable as proofs. You cannot prove it logically because its contradiction does not entail a contradiction, and you cannot prove it empirically because neither a proof nor the criterion of acceptability are empirical entities. Thus scientism (the premise that only scientific proofs count as proofs) is not scientific; it is a dogma of faith, a religion.
The first reason for believing in life after death is simply that there is no compelling reason not to, no objection to it that cannot be answered. The two most frequent objections are as follows:
Now this objector either means by 'evidence' merely empirical evidence, or else any kind of evidence. If he means the latter, he ignores all the following proofs for life after death. There is a lot of evidence. If he means the former, he falls victim to the self-contradiction argument just mentioned. There is no empirical evidence that the only kind of evidence we should accept is empirical evidence.
In most supposedly scientific objections of this type, an impossible demand is made, overtly or covertly — a demand for scientific proof — and then the belief is faulted for not satisfying that demand. This is like arguing against the existence of God on the grounds that "I have not found Him in my test tube," or like the first Soviet cosmonauts' "argument" that they had found no God in outer space. Ex hypothesi, if God exists He is not found in a test tube or in space. That would make Him a chemical or a meteor. A taxi trip through Cleveland disproves quasars as well as a laboratory experiment disproves God, or brain chemistry disproves the soul or its immortality. The demand that non-empirical entities submit to empirical verification is a self-contradictory demand. The belief that something exists outside a system cannot be disproved by observing the behavior of that system. Goldfish cannot disprove the existence of their human owners by observing water currents in the bowl.
What does the observed dependence of mind upon matter prove, if not the mortality of the soul? Wait. First, just what do we observe? We observe the physical manifestations of consciousness (e.g. speech) cease when the body dies. We do not observe the spirit cease to exist, because we do not observe the spirit at all, only its manifestations in the body. Observations of the body do not decide whether that body is an instrument of an independent spirit which continues to exist after its body-instrument dies, or whether the body is the cause of a dependent spirit which dies when its cause dies. Both hypotheses account for the observed facts.
When a body is paralyzed, the mind and will are still operative, though deprived of expression. Bodily death may be simply total paralysis. When you take a microphone away from a speaker, he can no longer be heard by the audience. But he is still a speaker. Body could be the soul's microphone. The dependence of soul on a body may be somewhat like the dependence of a ship on a dry-dock. Ships are not built on the open sea, but on dry-dock; but once they leave the dry-dock, they do not sink but become free floating ships. The body may be the soul's dry-dock, or (an even better metaphor) the soul's womb, and its death may be the soul's emergence from its womb.
What about the analogy of the candle? Even in the analogy, the light does not go out; it goes up. It is still traveling through space, observable from other planets. It 'goes out' as a child goes out to play; it is liberated.
But what of the need for a brain to think? The brain may not be the cause of thought but the stopping down, the 'reducing valve' for thought, as Bergson, James and Huxley suppose: an organ of forgetting rather than remembering, eliminating from the total field of consciousness all that serves no present purpose. Thus when the brain dies, more rather than less consciousness occurs: the floodgates come down. This would account for the familiar fact that dying people remember the whole of their past life in an instant with intense clarity, detail, and understanding.
In short, the evidence, even the empirical evidence, seems at least as compatible with soul immortality as with soul-mortality.
According to the medievals, the most logical of philosophers, "the argument from authority is the weakest of arguments." Nevertheless, it is an argument, a probability, a piece of evidence. Forty million Frenchmen can be wrong, but it is less likely than four Frenchmen being wrong.
The first argument from authority for life after death is simply quantitative: "the democracy of the dead" votes for it. Almost all cultures before our own have strongly, even officially, believed in some form of it. Children naturally and spontaneously believe in it unless conditioned out of it.
A second argument from authority is stronger because it is qualitative rather than quantitative: nearly all the sages have believed in it. We must not, of course, answer the challenge 'How do you know they were sages?' by saying 'Because they believed'; that would be begging the question pure and simple. But thinkers considered wise for other reasons have believed; why should this one belief of theirs be an exception to their wisdom?
Finally, we have the supreme authority of the teachings of Jesus. Belief in life after death is central to His entire message, "the Kingdom of Heaven." Even if you do not believe He is the incarnate God, can you believe He is a naive fool?
Arguments from reason are logically stronger than arguments from authority. The premises, or evidence, for arguments from reason can be taken from three sources, three levels of reality what is less than ourselves (Nature), ourselves (human life), or what is more than ourselves (God). Again, we move from the weaker to the stronger argument.
We could argue from the principle of the conservation of energy. We never observe any form of energy either created or destroyed, only transformed. The immortality of the soul seems to be the spiritual equivalent of the conservation of energy. If even matter is immortal, why not spirit?
The next class of arguments is taken from the nature of Man. What in us survives death depends on what is in us now. Death is like menopause. If a woman has in her identity nothing but her motherhood, then her identity has trouble surviving menopause. Life after menopause is a little like life after death.
The simplest and most obvious of these arguments may be called Primitive Man's Argument from Dead Cow. Primitive Man has two cows. One dies. What is the difference between Dead Cow and Live Cow? Primitive man looks. (He's really quite bright.) There appears no material difference in size or weight immediately upon death. Yet there is an enormous difference; something is missing. What? Life, of course. And what is that? The answer is obvious to any intelligent observer whose head is not clouded with theories: life is what makes Live Cow breathe. Life is breath. (The word for 'soul', or 'life', and 'breath' is the same in many ancient languages.) Soul is not air, which is still in Dead Cow's lungs, but the power to move it.
Life, it is seen, is not a material thing, like an organ. It is the life of the organs, of the body; not that which lives but that by which we live. Now this source of life cannot die as the body dies: by the removal of the soul. Soul cannot have soul taken from it. What can die has life on loan; life does not have life on loan.
The 'catch' in this argument is that this 'soul' may in turn have its life on loan from a higher source, and transmit it to the body only after having been given life first. This is in fact the Biblical teaching, contrary to the Greek view of the soul's inherent, necessary and eternal immortality. God gives souls life, and souls can die if they refuse it. But in any case the soul survives the body's death.
Another quite simple piece of evidence for the presence of an immaterial reality (soul) in us which is not subject to the laws of matter and its death, is the daily experience of real magic: the power of mind over matter. Every time I deliberately move my arm, I do magic. If there were no mind and will commanding the arm, only muscles; if there were muscles and a nervous system and even a brain but no conscious mind commanding them; then the arm could not rise unless it were lighter than air. When the body dies, its arms no longer move; the body reverts to obedience to merely material laws, like a sword dropped by a swordsman.
Even more simply stated, mind is not part of the system of matter, not measurable by material standards (How many inches long is your mind?) Therefore it need not die when the material body dies. The argument is so simple and evident that one wonders who the real 'primitive' is, the 'savage' who understands it or the sophisticated modern materialist who cannot understand the difference between mind and brain.
A traditional Scholastic argument for an immortal soul is taken from the presence of two operations which are not operations of the body (1) abstract thinking, as distinct from external sensing and internal imagining; and (2) deliberate, rational willing, as distinct from instinctive desiring. My thought is not limited to sense images like pyramids; it can understand abstract universal principles like triangles. And my choices are not limited to my body's desires and instincts. I fast, therefore I am.
Still another power of the soul which indicates that it is not a part or function of the body and therefore not subject to its laws and its mortality is the power to objectify its body. I can know a stone only because I am more than a stone. I can remember my past. (My present is alive; my past is dead.) I can know and love my body only because I am more than my body. As the projecting machine must be more than the images projected, the knower must be more than the objects known. Therefore I am more than my body.
Still another argument from the nature of soul, or spirit, is that it does not have quantifiable, countable parts as matter does. You can cut a body in half but not a soul; you can't have half a soul. It is not extended in space. You don't cut an inch off your soul when you get a haircut.
Since soul has no parts, it cannot be decomposed, as a body can. Whatever is composed (of parts) can be decomposed: a molecule into atoms, a cell into molecules, an organ into cells, a body into organs, a person into body and soul. But soul is not composed, therefore not decomposable. It could die only by being annihilated as a whole. But this would be contrary to a basic law of the universe: that nothing simply and absolutely vanishes, just as nothing simply pops into existence with no cause.
But if the soul dies neither in parts (by decomposition) nor as a whole by annihilation, then it does not die.
One last argument for immortality from the present experience of what soul is, comes from Plato. It is put so perfectly in the Republic that I quote it in its original form, adding only numbers to distinguish the steps of the argument:
We could first argue from God's justice. Since God is just, His dealings with us must be just, at least in the long run, in the total picture. ("The long run" is the answer to the problem of evil, the apparently unjust distribution of suffering.) The innocent suffer and the wicked flourish here; therefore 'here' cannot be 'the long run,' the total picture. There must be justice after death to compensate for injustice before death. (This is the point of Jesus' parable of the rich man and Lazarus.)
The next argument, from God's love, is stronger than the one from His justice because love is more essential to God. Love is God's essence; justice is one of His attributes — one of Love's attributes.
Love is "the fulfillment of the whole law." Each of the Ten Commandments is a way of loving. "Thou shalt not kill" means "Love does not kill." If you love someone, you don't kill him. But God IS love. Therefore God does not kill us. We want human life to triumph over death in the end because we love; is God less loving than we? Is He a hypocrite? Does He refuse to practice what He preaches?
Only if God does not love us or is impotent to do what He wills, do we die forever. That is, only if God is bad or weak — only if God is not God — is death the last word.
Whether the premises be taken from the nature of the world, of man, or of God, the last three arguments were all deductive, arguments by rational analysis. More convincing for most people are arguments from experience. These can be subdivided into two classes: arguments from experiences everyone, or nearly everyone, shares; and arguments from extraordinary or unusual experiences. The first class includes:
Three arguments from unusual or extraordinary experience are:
