A protean freethinker who experimented with Mu'tazilism and Shi'ism before finally embracing atheism, Ibn al-Rawandi was condemned by most Muslims as a dangerous heretic...In these works alone, he (1) rejects all religious dogmas as unacceptable to reason, (2) argues that prophets - Muhammad included - are like sorcerers and magicians, and that their miracles are entirely fictitious, (3) questions the necessity of prophecy and revelation if God is indeed all-powerful, (4) denies that the Qur'an is the revealed word of God and that it has any unique aesthetic value, (5) maintains that the God of the Quran is ultimately all-too-human and imperfect (i.e. lacking in knowledge and wisdom, easily angered, quick to punish, excessive, arbitrary, and unjust), (6) argues that the world is eternal and we are by no means compelled to posit a first divine cause, and (7) points out that Paradise as described in the Qur'an does not seem particularly desirable.

Early in his life, Ibn al-Rawandi was a Mutazilite scholar, who, like all Mutazilite scholars sought to apply Greek philosophy to explicate Islamic theology. After rejecting Mutazilism, he turned for a while to Shi'ism. At some point, however, and for reasons that are apparently unknown, al-Rawnadi became a free thinker and repudiated Islam and revealed religion.

In sum, with Hume's agnosticism and Bentham's atheism, the fundamental voluntarist thesis about the gulf between the divine and the human mind reaches new depths, and this serves to reinforce and radicalize the rejection, begun by Pufendorf, of Grotian rights-theory as the appropriate means of formulating the conventionalist theory of the moral life.

- "But tragically, Comte's "remarkable clearness and extent of vision as to natural things" was coupled with a "total blindness in regard to all that pertains to man's spiritual nature and relations." His "astonishing philosophic power" served only to increase the "plausibility" of a dangerous infidelity. Comte was, once unmasked, a "blank, avowed, unblushing Atheist." [...] Some of the Reformed writers were careful enough to note that technically Comte was not an atheist since he never denied the existence of God, merely his comprehensibility. Practically, however, this made little difference. It only pointed to the skepticism and nescience at the core of his positivism. The epistemological issues dominated the criticism of Comte.

- "So when I say “I rightly pass as an atheist” I know that because of everything that I’ve done so far, say in terms of deconstruction and so on and so forth, I’ve given a number of signs of my being a non-believer in God in a certain way, an atheist. And nevertheless, although I confirm that it is right to say “I’m an atheist”, I can’t say myself “I am an atheist” as a position, see “I am” or “I know what I am”: “I am this, and nothing else and I’m identifying myself as an atheist.” I would never say… this would sound obscene: “I am.” I wouldn’t say “I am an atheist” or I wouldn’t say “I am a believer” either."

With respect to his personal beliefs, Dewey wrote to Max Otto that “I feel the gods are pretty dead, tho I suppose I ought to know that however, to be somewhat more philosophical in the matter, if atheism means simply not being a theist, then of course I'm an atheist. But the popular if not the etymological significance of the word is much wider. ...Although he described himself as an atheist in one sense of the term, it is also clear that Dewey was opposed to militant atheism for the same reason that he was opposed to supernaturalism: he thought both positions dogmatic.

He was, at this stage of his life, obsessed with religion. He believed in the virgin birth and the voice of the devil, and was a devout Presbyterian (Prior 1940)...In later life, however, he described himself as having ‘no religious beliefs’ (Prior c.1967).

He was influenced for several years by the theologian Arthur Miller, who combined a strict adherence to Presbyterian doctrine with an equally strong support for socialism and opposition to nationalism. But Prior's pacifism weakened, and he served from 1942 to 1945 in the New Zealand air force. And the central focus of his interests gradually shifted - helped by an occasional bout of atheism - from theology to ethics and logic.

- Russell said: "As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one prove that there is not a God. On the other hand, if I am to convey the right impression to the ordinary man in the street I think I ought to say that I am an Atheist... None of us would seriously consider the possibility that all the gods of Homer really exist, and yet if you were to set to work to give a logical demonstration that Zeus, Hera, Poseidon, and the rest of them did not exist you would find it an awful job. You could not get such proof. Therefore, in regard to the Olympic gods, speaking to a purely philosophical audience, I would say that I am an Agnostic. But speaking popularly, I think that all of us would say in regard to those gods that we were Atheists. In regard to the Christian God, I should, I think, take exactly the same line."

Positivists did not merely reject religious discourse as meaningless, they rejected religion. They thought of religious belief as confused and nonsensical. ...their unofficial leader, Moritz Schlick, thought of religion as a kind of childhood phase in the intellectual development of humankind, a phase that will wither and become obsolete as scientific ways of knowing become the accepted paradigm.

For Kant, the mathematical sublime, as seen for example in the starry heavens, suggests to imagination the infinite, which in turn leads by subtle turns of contemplation to the concept of God. Schopenhauer's atheism will have none of this, and he rightly observes that despite adopting Kant's distinction between the dynamical and mathematical sublime, his theory of the sublime, making reference to the struggles and sufferings of struggles and sufferings of Will, is unlike Kant's.
