Seeing that man is the goal towards which everything has tended from the beginning, seeing that the same eternal and infinite Energy has laboured through the ages at the production of man, and man is the heir of the ages, nothing conceivable seems too great or glorious to believe concerning his destiny.... If there is no limit to human growth in knowledge and wisdom, in love and constructive power, in beauty and joy, we are invested with a magnificent worth and dignity.
So fallacy and folly run on. What, for example, does anyone mean by man as the goal towards which everything has tended since the beginning? Whatever truth there is in the statement applies to all things without exception. It is as true of the microbe as it is of man. If the "infinite and eternal Energy" laboured to produce man, it laboured also to produce the microbe which destroys him. The one is here as well as the other; and one can conceive a religious microbe thanking an almighty one for having created it, and declaring that unless it is to live for ever in some microbic heaven, with a proper supply of human beings for its nourishment, the whole scheme of creation is a failure. It is quite a question of the point of view. As a matter of fact there are no "ends" in nature. There are only results, and each result becomes a factor in some further result. It is human folly and ignorance which makes an end of a consequence.
After all, what reason is there for anyone assuming that the survival of man beyond the grave is even probably true? We do not know man as a "soul" first and a body afterwards. Neither do we know him as a detached "mind" which afterwards takes possession of a body. Our knowledge of man commences with him, as does our knowledge of any animal, as a body possessing certain definite functions of which we call one group mental. And the two things are so indissolubly linked that we cannot even think of them as separate. If anyone doubts this let him try and picture to himself what a man is like in the absence of a body. He will find the thing simply inconceivable. In the absence of the material organism, to which the mind unquestionably stands in the relation of function to organ, what remains is a mere blank. To the informed mind, that is. To the intelligence of the savage, who is led, owing to his erroneous conception of things, to think of something inside the body which leaves it during sleep, wanders about, and then returns on awakening, and who because of this affiliates sleep to death, the case may be different. But to a modern mind, one which is acquainted with something of what science has to say on the subject, the conception of a mind existing apart from organization is simply unthinkable. All our knowledge is against it. The development of mind side by side with the development of the brain and the nervous system is one of the commonplaces of scientific knowledge. The treatment of states of mind as functions of the brain and the nervous system is a common-place of medical practice. And the fact that diet, temperature, health and disease, accidents and old age, all have their effects on mental manifestations is matter of everyday observation. The whole range of positive science may safely be challenged to produce a single indisputable fact in favour of the assumption that there exists anything about man independent of the material organism.
All that can be urged in favour of such a belief is that there are still many obscure facts which we are not altogether able to explain on a purely mechanistic theory. But that is a confession of ignorance, not an affirmation of knowledge. At any rate, there does not exist a single fact against the functional theory of mind. All we know is decidedly in its favour, and a theory must be tested by what we know and by what it explains, not by what we do not know or by what it cannot explain. And there is here the additional truth that the only ground upon which the theory can be opposed is upon certain metaphysical assumptions which are made in order to bolster up an already existing belief. If the belief in survival had not been already in existence these assumptions would never have been made. They are not suggested by the facts, they are invented to support an already established theory, which can no longer appeal to the circumstances which gave it birth.
And about those circumstance there is no longer the slightest reason for justifiable doubt. We can trace the belief in survival after death until we see it commencing in the savage belief in a double that takes its origin in the phenomena of dreaming and unusual mental states. It is from that starting point that the belief in survival takes its place as an invariable element in the religions of the world. And as we trace the evolution of knowledge we see every fact upon which was built the belief in a double that survived death gradually losing its hold on the human intelligence, owing to the fact that the experiences that gave it birth are interpreted in a manner which allows no room for the religious theory. The fatal fact about the belief in survival is its history. That history shows us how it began, as surely as the course of its evolution indicates the way in which it will end.
So, as with the idea of God, what we have left in modern times are not the reasons why such a belief is held, but only excuses why those who hold it should not be disturbed. That and a number of arguments which only present an air of plausibility because they succeed in jumbling together things that have no connection with each other. As an example of this we may take the favourite modern plea that a future life is required to permit the growth and development of the individual. We find this expressed in the quotation above given in the sentence "if there is no limit to human growth, etc.," the inference being that unless there is a future life there is a very sharp limit set to human growth, and one that makes this life a mockery. This plea is presented in so many forms that it is worth while analysing it a little, if only to bring out more clearly the distinction between the religious and the Freethought view of life.
What now is meant by there being no limit to human growth? If by it is meant individual growth, the reply is that there is actually a very sharp limit set to growth, much sharper than the average person seems to be aware of. It is quite clear that the individual is not capable of unlimited growth in this world. There are degrees of capacity in different individuals which will determine what amount of development each is capable of. Capacity is not an acquired thing, it is an endowment, and the child born with the brain capacity of a fool will remain a fool to the end, however much his folly may be disguised or lost amid the folly of others. And with each one, whether he be fool or genius, acquisitions are made more easily and more rapidly in youth, the power of mental adaptation is much greater in early than in later life, while in old age the capacities of adaptation and acquisition become negligible quantities. And provided one lives long enough, the last stage sees, not a promise of further progress if life were continued, but a process of degradation. The old saying that one can't put a quart into a pint pot is strictly applicable here. Growth assumes acquisition; acquisition is determined by capacity, and this while an indefinite quantity (indefinite here is strictly referable to our ignorance, not to the actual fact) is certainly not an unlimited one. Life, then, so far as the individual is concerned, does not point to unlimited growth. It indicates, so far as it indicates anything at all, that there is a limit to growth as to all other things.
Well, but suppose we say that man is capable of indefinite growth, what do we mean? Let us also bear in mind at this point that we are strictly concerned with the individual. For if man survives death he must do it as an individual. To merely survive as a part of the chemical and other elements of the world, or, to follow some mystical theologians, as an indistinguishable part of a "world-soul," is not what people mean when they talk of living beyond the grave. Here, again, it will be found that we have confused two quite distinct things, even though the one thing borrows its meaning from the other.
When we compare the individual, as such, with the individual of three or four thousand years ago, can we say with truth that the man of to-day is actually superior to the man of the earlier date? To test the question let us put it in this way. Does the man of to-day do anything or think anything that is beyond the capacity of an ancient Egyptian or an ancient Greek, if it were possible to suddenly revive one and to enable him to pass through the same education that each one of us passes through? I do not think that anyone will answer that question in the affirmative. Reverse the process. Suppose that a modern man, with exactly the same capacity that he now has had lived in the days of the ancient Egyptians or the ancient Greeks, can we say that his capacity is so much greater than theirs, that he would have done better than they did? I do not think that anyone will answer that question in the affirmative either. Is the soldier of to-day a better soldier, or the sailor a better sailor than those who lived three thousand years ago? Once more the answer will not be in the affirmative. And yet there are certain things that are obvious. It is plain that we all know more than did the people of long ago, we can do more, we understand the past better, and we can see farther into the future. A schoolboy to-day carries in his head what would have been a philosopher's outfit once upon a time. Our soldiers and sailors utilize, single-handed, forces greater than a whole army or navy wielded in the far-off days of the Ptolemies. We call ourselves greater, we think ourselves greater, and in a sense we are greater than the people of old. What, then, is the explanation of the apparent paradox?
The explanation lies in the simple fact that progress is not a phenomenon of individual life at all. It is a phenomenon of social existence. If each generation had to commence at the exact point at which its predecessors started it would get no farther than they got. It would be an eternal round, with each generation starting from and reaching the same point, and progress would be an inconceivable thing. But that we know is not the case. Instead of each generation starting from precisely the same point, one inherits at least something of the labours and discoveries of its predecessors. A thing discovered by the individual is discovered for the race. A thought struck out by the individual is a thought for the race. By language, by tradition, and by institutions the advances of each generation are conserved, handed on, and made part of our racial possessions. The strength, the knowledge, of the modern is thus due not to any innate superiority over the ancient, but because one is modern and the other ancient. If we could have surrounded the ancient Assyrians with all the inventions, and given them all the knowledge that we possess, they would have used that knowledge and those inventions as wisely, or as unwisely as we use them. Progress is thus not a fact of individual but of racial life. The individual inherits more than he creates, and it is in virtue of this racial inheritance that he is what he is.
