On the other hand Bohr wrote of his admiration for the writing and presentation of Kierkegaard – at the same time stating he could not accept some of it.

"Bohr's atheism, the counterpiece of Einstein's monotheism, ... was more affined to traditional Far Eastern philosophy,” according to Stent. ...The young Bohr thus lived in two worlds, but mostly the cultural Christianity of the Danish middle class. As a young man, he had read Søren Kierkegaard, a fellow Dane and a Christian existentialist from the nineteenth century, with some enthusiasm. But he finally faced a religious crisis, and by the time he went to England to study physics, the idea of God had lost its appeal. The aim of life was happiness, he wrote his fiancée, making it impossible “that a person must beg from and bargain with fancied powers infinitely stronger than himself." ... In his only published paper on the topic of religion, Bohr spoke not of deities and doctrines but of psychological experience.

A statement about religion in the loose notes on Kierkegaard may throw light on the notion of wildness that appears in many of Bohr's letters. “I, who do not feel in any way united with, and even less, bound to a God, and therefore am also much poorer [than Kierkegaard], would say that the good [is] the overall lofty goal, as only by being good [can one] judge according to worth and right.”

Bohr's sort of humor, use of parables and stories, tolerance, dependence on family, feelings of indebtedness, obligation, and guilt, and his sense of responsibility for science, community, and, ultimately, humankind in general, are common traits of the Jewish intellectual. So too is a well-fortified atheism. Bohr ended with no religious belief and a dislike of all religions that claimed to base their teachings on revelations.

- Werner Heisenberg recollects a friendly conversation among young participants at the 1927 Solvay Conference about Einstein's and Planck's views on religion.

If we are honest — and as scientists honesty is our precise duty — we cannot help but admit that any religion is a pack of false statements, deprived of any real foundation. The very idea of God is a product of human imagination.[...] I do not recognize any religious myth, at least because they contradict one another.[...]" Pauli jokingly said: "Well, I'd say that also our friend Dirac has got a religion and the first commandment of this religion is: God does not exist and Paul Dirac is his prophet."

Dirac was contemptuous of philosophy and, as many scientists do, professed atheism. But it was a narrow sort, mainly dismissive of religious orthodoxy. In notes he wrote in 1933, he embraces another creed: "[T]his article of faith is that the human race will continue to live for ever and will develop and progress without limit . . .

An atheist, he was buried under a gravestone chosen by Manci. It read “because God said it should be so”.

- What I don't like about Richard [Dawkins] is not so much what he knows or doesn't know as the dogmatic way in which he says things. I think that is a poor advertisement for science, because the whole thing about being a scientist is that you shouldn't be prejudiced, you should have an open mind. So, I don't believe in God but that is a belief, not some thing I know. I believe I love my husband, but I couldn't prove it to you one way or the other. How could I? I just know I do. My particular belief is that there is no Deity out there, but I can't prove it and therefore I would not have the temerity to tell other people they're wrong. The coinage of proof is not appropriate for belief and Dawkins thinks it is. But if you keep an open mind, that doesn't mean you swallow anything whole.

There is a need in us to try to understand, to see that there is something that unites us spiritually. So scientists who do not respect religion fail in their most basic task—observation. Human beings need the spiritual. The same observation reveals to me a multitude of religious constructions—gods of nature, spirits, the great monotheistic religions.

[...] In retrospect, the final steps seem as sudden as they were painless. [...] As I looked upward [at the night sky], I realised that the sole prospect was limitless expanse of unthreatening and impersonal emptiness — but for unapproachable galaxies — of a universe without purpose of punishment or reward for a lately arrived animal species, free to make or mar its own destiny without help or hindrance from above."

You can be tolerant of it and say, I don't believe in this but I don't mind if other people do, or you can say, I not only don't believe in it but I think it is dangerous and damaging for other people to believe in it and they should be persuaded that they are mistaken. I fluctuate between the two. I am tolerant because religious institutions facilitate some very important work that would not get done otherwise, but then I look around and see what an incredible amount of damage religion is doing.

[...] Considered as an element of the world, God has the same degree and kind of objective reality as do other products of mind.

- "When we reflect on anything for long enough, we're likely to end up with what we sometimes call "basic" questions – ones we can see no way at all to answer. For we have no perfect way to answer even this question: How can one tell when a question has been properly answered? What caused the universe, and why? What is the purpose of life? How can you tell which beliefs are true? How can you tell what is good? These questions seem different on the surface, but all of them share one quality that makes them impossible to answer: all of them are circular! You can never find a final cause, since you must always ask one question more: "What caused that cause?" You can never find any ultimate goal, since you're always obliged to ask, "Then what purpose does that serve?" Whenever you find out why something is good-or is true-you still have to ask what makes that reason good and true. No matter what you discover, at every step, these kinds of questions will always remain, because you have to challenge every answer with, "Why should I accept that answer?" Such circularities can only waste our time by forcing us to repeat, over and over and over again, "What good is Good?" and, "What god made God?" " Marvin Minsky. The Society of Mind.

- "[Religion] is not an easy subject to deal with, but as zoologists we must do our best to observe what actually happens rather than listen to what is supposed to be happening. If we do this, we are forced to the conclusion that, in a behavioural sense, religious activities consist of the coming together of large groups of people to perform repeated and prolonged submissive displays to appease a dominant individual. The dominant individual takes many forms in different cultures, but always has the common factor of immense power. [...] If these submissive actions are successful, the dominant individual is appeased. [...] The dominant individual is usually, but not always, referred to as a god. Since none of these gods exist in a tangible form, why have they been invented? To find the answer to this we have to go right back to our ancestral origins."

Like real parents they would both protect, punish and be obeyed. [...] These — the houses of the gods — the temples, the churches and the cathedrals — are buildings apparently made for giants, and a space visitor would be surprised to find on closer examination that these giants are never at home.

In one respect, however, he is not a romantic: he does not idealize the person of the beloved, his highest praise is to consider her his equal. "When you feel your own equal in the body of a beautiful woman, just as ready to forget the world for you as you for her – oh my good Lord – who can describe what happiness then. You can live it, now and again – you cannot speak of it." Of course, he does speak of it, and almost always with religious imagery. Yet at this time he also wrote, "By the way, I never realized that to be nonbelieving, to be an atheist, was a thing to be proud of. It went without saying as it were." And in another place at about this same time: "Our creed is indeed a queer creed. You others, Christians (and similar people), consider our ethics much inferior, indeed abominable. There is that little difference. We adhere to ours in practice, you don't." Whatever problems they may have had in their love affair, the pangs of conscience were not among them. Sheila was as much an unbeliever as Erwin, but in a less complex, more realistic way. She was never entirely convinced by his vedantic theology.

In terms of religion, Schrodinger fits in the atheist camp. He even lost a marriage proposal to his love, Felicie Krauss, not only due to his social status but his lack of religious affiliation. He was known as a freethinker who did not believe in god. But interestingly Schrodinger had a deep connection to Hinduism, Buddhism, and Eastern philosophy in general. Erwin studied numerous books on Eastern thought as well as the Hindu scriptures. He was enthralled with Vedanta thought and connected ideas of oneness and unity of mind with his research on quantum physics, specifically wave mechanics.

Schopenhauer often called himself an atheist, as did Schrodinger, and if Buddhism and Vedanta can be truly described as atheistic religions, both the philosopher and his scientific disciple were indeed atheists. They both rejected the idea of a "personal God," and Schopenhauer thought that "pantheism is only a euphemism for atheism."

This work, first published under the pseudonym William Hammon, was subsequently republished by Richard Carlile in 1826. In the pamphlet Turner declared that he was an atheist, though he did admit that the 'vis naturae', gravity, and matter's elasticity and repulsive powers demonstrated that the universe was permeated by 'a principle of intelligence and design' (ibid., 17).

Goodheart describes him as "an evangelical atheist, an impassioned actuary, a liberal who advocated state regulation, an individualist who championed social cooperation, and a very private public crusader" (op. cit., page x)

Zwicky has dealt critically with religion during his whole life. A 1971 diary entry states: "To base the inexplainabilty and the immense wonder of nature upon another miracle, God, is unnecessary and not acceptable for any serious thinker." According to one story, Zwicky once discussed the beginning of the universe with a priest. The priest, quoting Scriptures, stated that the universe had started with "and there is light."
