My Parents had early given me religious Impressions, and brought me through my Childhood piously in the Dissenting Way. But I was scarce 15 when, after doubting by turns of several Points as I found them disputed in the different Books I read, I began to doubt of Revelation itself. Some Books against Deism fell into my Hands; they were said to be the Substance of Sermons preached at Boyle's Lectures. It happened that they wrought an Effect on me quite contrary to what was intended by them: For the Arguments of the Deists which were quoted to be refuted, appeared to me much Stronger than the Refutations. In short I soon became a thorough Deist.[Part I, p. 45 of autobiography]

Occasionally, I get a letter from someone who is in “contact” with extraterrestrials. I am invited to “ask them anything.” And so over the years I’ve prepared a little list of questions. The extraterrestrials are very advanced, remember. So I ask things like, “Please provide a short proof of Fermat’s Last Theorem.” Or the Goldbach Conjecture. And then I have to explain what these are, because extraterrestrials will not call it Fermat’s Last Theorem. So I write out the simple equation with the exponents. I never get an answer. On the other hand, if I ask something like “Should we be good?” I almost always get an answer.

It is also worth noting that one can obtain a Ph.D. in any branch of science for no other purpose than to make cynical use of scientific language in an effort to rationalize the glaring inadequacies of tbe Bible. A handful of Christians appear to have done this; some have even obtained their degrees from reputable universities. No doubt, others will follow in their footsteps. While such people are technically "scientists," they are not behaving like scientists. They simply are not engaged in an honest inquiry into the nature of the universe. And their proclamations about God and the failures of Darwinism do not in the least signify that there is a legitimate scientific controversy about evolution.

Those whose acquaintance with scientific research is derived chiefly from its practical results easily develop a completely false notion of the mentality of the men who, surrounded by a skeptical world, have shown the way to kindred spirits scattered wide through the world and through the centuries. Only one who has devoted his life to similar ends can have a vivid realization of what has inspired these men and given them the strength to remain true to their purpose in spite of countless failures. It is cosmic religious feeling that gives a man such strength. A contemporary has said, not unjustly, that in this materialistic age of ours the serious scientific workers are the only profoundly religious people.

Philo of Larisa, head of the Academy in Athens....inspired Cicero with a passion for philosophy, and in particular for the theories of Skepticism, which asserted that knowledge of the nature of things is in the nature of things unattainable. Such ideas were well judged to appeal to a student of rhetoric who had learned to argue all sides of a case. In his early twenties Cicero wrote the first two volumes of a work on 'inventin'--that is to say, the technique of finding ideas and arguments for a speech; in it he noted that the most important thing was 'that we do not recklessly and presumptuously assume something to be true.' This resolute uncertainty was to be a permanent feature of his thought.

...Spinoza’s Conjecture:“Belief comes quickly and naturally, skepticism is slow and unnatural, and most people have a low tolerance for ambiguity.The scientific principle that a claim is untrue unless proven otherwise runs counter to our natural tendency to accept as true that which we can comprehend quickly. Thus it is that we should reward skepticism and disbelief, and champion those willing to change their mind in the teeth of new evidence. Instead, most social institutions-most notably those in religion, politics, and economics-reward belief in the doctrines of the faith or party or ideology, punish those who challenge the authority of the leaders, and discourage uncertainty and especially skepticism.

Are you really surprised by the endurance of religion? What ideology is likely to be more durable than one that conforms, at every turn, to our powers of wishful thinking? Hope is easy; knowledge is hard. Science is the one domain in which we human beings make a truly heroic effort to counter our innate biases and wishful thinking. Science is the one endeavor in which we have developed a refined methodology for separating what a person hopes is true from what he has good reason to believe. The methodology isn't perfect, and the history of science is riddled with abject failures of scientific objectivity. But that is just the point-these have been failures of science, discovered and corrected by-what, religion? No, by good science.

I perceive that it is far more practical to begin at the beginning and discuss theories. I see that the men who killed each other about the orthodoxy of the Homoousion were far more sensible than the people who are quarrelling about the Education Act. For the Christian dogmatists were trying to establish a reign of holiness, and trying to get defined, first of all, what was really holy. But our modern educationists are trying to bring about a religious liberty without attempting to settle what is religion or what is liberty. If the old priests forced a statement on mankind, at least they previously took some trouble to make it lucid. It has been left for the modern mobs of Anglicans and Nonconformists to persecute for a doctrine without even stating it.

What I admire about the modern atheist is not at all his logic, but rather his gift of imagination. There will always be the cartoon versions of Christianity further perpetuated by the extremist atheists who do not possess the humility to ask real scholars and theologians its difficult questions. There is little doubt that the atheist has the bigger imagination: the first reason is due to his persistent caricatures of what constitutes a Christian; the second because of his belief that most of his questions are actually rhetorical. From this I can infer that, instead of laughing at one another - the Christian at modern atheist immaturity and the modern atheist at Christian stupidity, we would have a better chance at productivity laughing with one another as we all dumb down what we don't understand.

You are clever man, friend John; you reason well, and your wit is bold; but you are too prejudiced. You do not let your eyes see nor your ears hear, and that which is outside your daily life is not of account to you. Do you not think that there are things which you cannot understand, and yet which are; that some people see things that others cannot? But there are things old and new which must not be contemplate by men’s eyes, because they know – or think they know – some things which other men have told them. Ah, it is the fault of our science that it wants to explain all; and if it explain not, then it says there is nothing to explain. But yet we see around us every day the growth of new beliefs, which think themselves new; and which are yet but the old, which pretend to be young – like the fine ladies at the opera.

I am approached with the most opposite opinions and advice, and that by religious men, who are equally certain that they represent the Divine will. I am sure that either the one or the other is mistaken in that belief, and perhaps in some respects both. I hope it will not be irreverent for me to say that if it is probable that God would reveal his will to others, on a point so connected with my duty, it might be supposed he would reveal it directly to me; for, unless I am more deceived in myself than I often am, it is my earnest desire to know the will of Providence in this matter. And if I can learn what it is, I will do it! These are not, however, the days of miracles, and I suppose it will be granted that I am not to expect a direct revelation. I must study the plain, physical facts of the case, ascertain what is possible and learn what appears to be wise and right.

It seems to me what is called for is an exquisite balance between two conflicting needs: the most skeptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas. Obviously those two modes of thought are in some tension. But if you are able to exercise only one of these modes, whichever one it is, you’re in deep trouble.If you are only skeptical, then no new ideas make it through to you. You never learn anything new. You become a crotchety old person convinced that nonsense is ruling the world. (There is, of course, much data to support you.) But every now and then, maybe once in a hundred cases, a new idea turns out to be on the mark, valid and wonderful. If you are too much in the habit of being skeptical about everything, you are going to miss or resent it, and either way you will be standing in the way of understanding and progress.On the other hand, if you are open to the point of gullibility and have not an ounce of skeptical sense in you, then you cannot distinguish the useful as from the worthless ones.

The real bible is not the work of inspired men, nor prophets, nor apostles, nor evangelists, nor of Christs. Every man who finds a fact, adds, as it were, a word to this great book. It is not attested by prophecy, by miracles or signs. It makes no appeal to faith, to ignorance, to credulity or fear. It has no punishment for unbelief, and no reward for hypocrisy. It appeals to man in the name of demonstration. It has nothing to conceal. It has no fear of being read, of being contradicted, of being investigated and understood. It does not pretend to be holy, or sacred; it simply claims to be true. It challenges the scrutiny of all, and implores every reader to verify every line for himself. It is incapable of being blasphemed. This book appeals to all the surroundings of man. Each thing that exists testifies of its perfection. The earth, with its forests and plains, its rocks and seas; with its every wave and cloud; with its every leaf and bud and flower, confirms its every word, and the solemn stars, shining in the infinite abysses, are the eternal witnesses of its truth.

You must picture me alone in that room in Magdalen, night after night, feeling, whenever my mind lifted even for a second from my work, the steady, unrelenting approach of Him whom I so earnestly desired not to meet. That which I greatly feared had at last come upon me. In the Trinity Term of 1929 I gave in, and admitted that God was God, and knelt and prayed: perhaps, that night, the most dejected and reluctant convert in all England. I did not then see what is now the most shining and obvious thing; the Divine humility which will accept a convert even on such terms. The Prodigal Son at least walked home on his own feet. But who can duly adore that Love which will open the high gates to a prodigal who is brought in kicking, struggling, resentful, and darting his eyes in every direction for a chance of escape? The words “compelle intrare,” compel them to come in, have been so abused be wicked men that we shudder at them; but, properly understood, they plumb the depth of the Divine mercy. The hardness of God is kinder than the softness of men, and His compulsion is our liberation.

On the other hand, we can all call to mind the case of seeing the same thing many times over and over. Everyone has had the experience of having their impression of a particular object change depending upon their feelings or conditions at a given moment. This is because the object is seen under the influence of the mental state of that moment. Of course, at the time when we are looking at something, we are generally not aware of the way our feelings are being protected into the situation.Seen in this way, our so-called cognition, or the action of discerning the meaning of things as they are perceived by us, is never in any case a perception of the external world exactly as it is, but rather a world that can only be apprehended via its interface with our present mental state. In other words, it is nothing other than our own mind that constructs things and determines their content. This is the meaning of "consciousness-only," or "nothing but the transformations of consciousness." And, if we turn this around, we ourselves are nothing other than things that dwell in a world defined by the limits of that which is knowable by the functions of our own mind.
