Schopenhauer's "Will" has nothing in common with the God-idea as commonly held, and he was bitterly anti-theistic. In a dialogue entitled "Religion," he places these words in the mouth of his character Philalethes: "A certain amount of general ignorance is the condition of all religions, the element in which alone they can exist. And as soon as astronomy, natural science, geology, history, the knowledge of countries and peoples, have spread their light broadcast, and philosophy finally is permitted to say a word, every faith founded on miracles and revelation must disappear; and philosophy takes its place."
Hegel's deification of thought or reason left no room for personal immortality, and his query, "Do you expect a tip for having nursed your ailing mother, and refrained from poisoning your brother?" is well known. A vague conception of a deity whose existence can be proved, if it can be proved at all, only by the abstruse arguments of a Hegel is not a god of practical service to the theists.
Schelling was pantheistic, and Feuerbach played havoc with the philosophic evidence for God and immortality and treated all religions as a dream and an illusion.
Herbert Spencer, James Mill, J. S. Mill, and Huxley popularized the agnostic standpoint. Spencer in his "First Principles" argues in this manner: "Those who cannot conceive of a self-existent Universe, and therefore assume a creator as the source of the Universe, take for granted that they can conceive a self-existent creator. The mystery which they recognize in this great fact surrounding them on every side, they transfer to an alleged source of this great fact, and then suppose that they have solved the mystery. But they delude themselves. Self-existence is inconceivable; and this holds true whatever be the nature of the object of which it is predicated. Whoever agrees that the atheistic hypothesis is untenable because it involves the impossible idea of self-existence, must perforce admit that the theistic hypothesis is untenable if it contains the same impossible idea.... If religion and science are to be reconciled, the basis of reconciliation must be this deepest, widest, and most certain of all facts, that the Power which the Universe manifests to us is inscrutable."
Nietzsche, the great liberator of modern thought, vigorously opposed religious morality, the influence of Christianity, and all religious beliefs. "When the natural consequences of an action," he wrote, "are no longer looked upon as natural, but are considered to be produced by the phantasms of superstition, by 'God,' 'Ghosts,' and 'Souls,' and appear as 'moral' consequences, as rewards, punishments, guidance and revelation, then the whole basis of knowledge is destroyed; and the greatest possible crime against humanity has been committed."
William James, claimed as a supporter of religion, argues that our inner experience makes us cognizant of a spiritual world. The advance of psychological research does not deal kindly with this contention, and such works as Leuba's "Psychology of Religious Mysticism" give a rational explanation of the mystic state. Moreover, James did not give his support to monotheism. "That vast literature of proofs of God's existence," he stated, "drawn from the order of nature, which a century ago seemed so overwhelmingly convincing, today does little more than gather dust in the libraries, for the simple reason that our generation has ceased to believe in the kind of God it argued for. Whatever sort of God may be, we know today that he is nevermore that mere external inventor of 'contrivances' intended to make manifest his 'glory' in which our great-grandfathers took such satisfaction."
James claimed to be a pluralist in the sense that there are several or many spiritual beings above us, and his writings lead one to believe that he was not convinced that man, as a distinct personality, survives the grave.
Royce rejected all the current arguments for God and immortality and argues for the mysticism of internal experience. Eucken offers no support to theologians; and Bergson does not seem to express a clear belief in a personal god or personal immortality.
Coming to the more popular of contemporary philosophers one finds that, just as the Greek philosophers reasoned outside the pale of the then held beliefs which were theistic, so do these modern philosophers reach conclusions that are outside the pale of organized religion of today. George Santayana is a materialist and sceptic who, in his "Reason in Religion," reveals his scepticism and frowns upon personal immortality. "It is pathetic," he comments, "to observe how lowly are the motives that religion, even the highest, attributes to the deity, and from what a hard-pressed and bitter existence they have been drawn. To be given the best morsel, to be remembered, to be praised, to be obeyed blindly and punctiliously, these have been thought points of honor with the gods, for which they would dispense favors and punishments on the most exhorbitant scale.... The idea that religion contains a literal, not a symbolic, representation of truth and life is simply an impossible idea. Whoever entertains it has not come within the region of profitable philosophizing on that subject."
Bertrand Russell, considered by some the keenest philosophical mind of the present age, is an agnostic who maintains "The objections to religion are of two sorts, intellectual and moral. The intellectual objection is that there is no reason to suppose any religion true; the moral objection is that religious precepts date from a time when men were more cruel than they are now, and therefore tend to perpetuate inhumanities which the moral conscience of the age would otherwise outgrow."
