"Let us now take up the thread of our enquiry. What, then, is the psychological significance of religious ideas [and teachings] and under what heading are we to classify them?...

There are, of course, many such teachings about the most various things in the world. Every school lesson is full of them. Let us take geography. We are told that the town of Constance lies on the Bodensee. A student song adds: ‘if you don’t believe it, go and see.’ I happen to have been there and can confirm the fact that that lovely town lies on the shore of a wide stretch of water which all those who live round it call the Bodensee; and I am now completely convinced of the correctness of this geographical assertion. In this connection I am reminded of another, very remarkable, experience. I was already a man of mature years when I stood for the first time on the hill of the Acropolis in Athens, between the temple ruins, looking out over the blue sea. A feeling of astonishment mingled with my joy. It seemed to say: ‘So it really is true, just as we learnt at school!’ How shallow and weak must have been the belief I then acquired in the real truth of what I heard, if I could be so astonished now! But I will not lay too much stress on the significance of this experience; for my astonishment could have had another explanation, which did not occur to me at the time and which is of a wholly subjective nature and has to do with the special character of the place.

All teachings like these, then, demand belief in their contents, but not without producing grounds for their claim. They are put forward as the epitomized result of a longer process of thought based on observation and certainly also on inferences. If anyone wants to go through this process himself instead of accepting its result, they show him how to set about it. Moreover, we are always in addition given the source of the knowledge conveyed by them, where that source is not self-evident, as it is in the case of geographical assertions. For instance, the earth is shaped like a sphere; the proofs adduced for this are Foucault’s pendulum experiment, the behaviour of the horizon and the possibility of circumnavigating the earth. Since it is impracticable, as everyone concerned realizes, to send every schoolchild on a voyage round the world, we are satisfied with letting what is taught at school be taken on trust; but we know that the path to acquiring a personal conviction remains open.

Let us try to apply the same test to the teachings of religion. When we ask on what their claim to be believed is founded, we are met with three answers, which harmonize remarkably badly with one another. Firstly, these teachings deserve to be believed because they were already believed by our primal ancestors; secondly, we possess proofs which have been handed down to us from those same primaeval times; and thirdly, it is forbidden to raise the question of their authentication at all. In former days anything so presumptuous was visited with the severest penalties, and even to-day society looks askance at any attempt to raise the question again.

This third point is bound to rouse our strongest suspicions. After all, a prohibition like this can only be for one reason -- that society is very well aware of the insecurity of the claim it makes on behalf of its religious doctrines. Otherwise it would certainly be very ready to put the necessary data at the disposal of anyone who wanted to arrive at conviction. This being so, it is with a feeling of mistrust which it is hard to allay that we pass on to an examination of the other two grounds of proof. We ought to believe because our forefathers believed. But these ancestors of ours were far more ignorant than we are. They believed in things we could not possibly accept to-day; and the possibility occurs to us that the doctrines of religion may belong to that class too. The proofs they have left us are set down in writings which themselves bear every mark of untrustworthiness. They are full of contradictions, revisions and falsifications, and where they speak of factual confirmations they are themselves unconfirmed. It does not help much to have it asserted that their wording, or even their content only, originates from divine revelation; for this assertion is itself one of the doctrines whose authenticity is under examination, and no proposition can be a proof of itself.

Thus we arrive at the singular conclusion that of all the information provided by our cultural assets it is precisely the elements which might be of the greatest importance to us and which have the task of solving the riddles of the universe and of reconciling us to the sufferings of life -- it is precisely those elements that are the least well authenticated of any. We should not be able to bring ourselves to accept anything of so little concern to us as the fact that whales bear young instead of laying eggs, if it were not capable of better proof than this.

This state of affairs is in itself a very remarkable psychological problem. And let no one suppose that what I have said about the impossibility of proving the truth of religious doctrines contains anything new. It has been felt at all times -- undoubtedly, too, by the ancestors who bequeathed us this legacy. Many of them probably nourished the same doubts as ours, but the pressure imposed on them was too strong for them to have dared to utter them. And since then countless people have been tormented by similar doubts, and have striven to suppress them, because they thought it was their duty to believe; many brilliant intellects have broken down over this conflict, and many characters have been impaired by the compromises with which they have tried to find a way out of it.

If all the evidence put forward for the authenticity of religious teachings originates in the past, it is natural to look round and see whether the present, about which it is easier to form judgements, may not also be able to furnish evidence of the sort. If by this means we could succeed in clearing even a single portion of the religious system from doubt, the whole of it would gain enormously in credibility. The proceedings of the spiritualists meet us at this point; they are convinced of the survival of the individual soul and they seek to demonstrate to us beyond doubt the truth of this one religious doctrine. Unfortunately they cannot succeed in refuting the fact that the appearance and utterances of their spirits are merely the products of their own mental activity. They have called up the spirits of the greatest men and of the most eminent thinkers, but all the pronouncements and information which they have received from them have been so foolish and so wretchedly meaningless that one can find nothing credible in them but the capacity of the spirits to adapt themselves to the circle of people who have conjured them up.

I must now mention two attempts that have been made -- both of which convey the impression of being desperate efforts -- to evade the problem. One, of a violent nature, is ancient; the other is subtle and modern. The first is the ‘Credo quia absurdum’ of the early Father of the Church.[‘I believe because it is absurd.’ This is attributed to Tertullian.] It maintains that religious doctrines are outside the jurisdiction of reason -- are above reason. Their truth must be felt inwardly, and they need not be comprehended. But this Credo is only of interest as a self-confession. As an authoritative statement it has no binding force. Am I to be obliged to believe every absurdity? And if not, why this one in particular? There is no appeal to a court above that of reason. If the truth of religious doctrines is dependent on an inner experience which bears witness to that truth, what is one to do about the many people who do not have this rare experience? One may require every man to use the gift of reason which he possesses, but one cannot erect, on the basis of a motive that exists only for a very few, an obligation that shall apply to everyone. If one man has gained an unshakable conviction of the true reality of religious doctrines from a state of ecstasy which has deeply moved him, of what significance is that to others?

The second attempt is the one made by the philosophy of ‘As if’. This asserts that our thought-activity includes a great number of hypotheses whose groundlessness and even absurdity we fully realize. They are called ‘fictions’, but for a variety of practical reasons we have to behave ‘as if’ we believed in these fictions. This is the case with religious doctrines because of their incomparable importance for the maintenance of human society. This line of argument is not far removed from the ‘Credo quia absurdum’. But I think the demand made by the ‘As if’ argument is one that only a philosopher could put forward. A man whose thinking is not influenced by the artifices of philosophy will never be able to accept it; in such a man’s view, the admission that something is absurd or contrary to reason leaves no more to be said. It cannot be expected of him that precisely in treating his most important interests he shall forgo the guarantees he requires for all his ordinary activities. I am reminded of one of my children who was distinguished at an early age by a peculiarly marked matter-of-factness. When the children were being told a fairy story and were listening to it with rapt attention, he would come up and ask: ‘Is that a true story?’ When he was told it was not, he would turn away with a look of disdain. We may expect that people will soon behave in the same way towards the fairy tales of religion, in spite of the advocacy of ‘As if’.

... At this point one must expect to meet with an objection. ‘Well then, if even obdurate sceptics admit that the assertions of religion cannot be refuted by reason, why should I not believe in them, since they have so much on their side -- tradition, the agreement of mankind, and all the consolations they offer?’ Why not, indeed? Just as no one can be forced to believe, so no one can be forced to disbelieve. But do not let us be satisfied with deceiving ourselves that arguments like these take us along the road of correct thinking. If ever there was a case of a lame excuse we have it here. Ignorance is ignorance; no right to believe anything can be derived from it. In other matters no sensible person will behave so irresponsibly or rest content with such feeble grounds for his opinions and for the line he takes. It is only in the highest and most sacred things that he allows himself to do so. In reality these are only attempts at pretending to oneself or to other people that one is still firmly attached to religion, when one has long since cut oneself loose from it. Where questions of religion are concerned, people are guilty of every possible sort of dishonesty and intellectual misdemeanour. Philosophers stretch the meaning of words until they retain scarcely anything of their original sense. They give the name of ‘God’ to some vague abstraction which they have created for themselves; having done so they can pose before all the world as deists, as believers in God, and they can even boast that they have recognized a higher, purer concept of God, notwithstanding that their God is now nothing more than an insubstantial shadow and no longer the mighty personality of religious doctrines. Critics persist in describing as ‘deeply religious’ anyone who admits to a sense of man’s insignificance or impotence in the face of the universe, although what constitutes the essence of the religious attitude is not this feeling but only the next step after it, the reaction to it which seeks a remedy for it. The man who goes no further, but humbly acquiesces in the small part which human beings play in the great world -- such a man is, on the contrary, irreligious in the truest sense of the word."
