I do not believe we can have any freedom at all in the philosophical sense, for we act not only under external compulsion, but also by inner necessity.... I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modelled after our own, a God, in short, who is but a reflection of human frailty. Neither can I believe that the individual survives the death of his body, although feeble souls harbor such thoughts through fear or ridiculous egotism. It is enough for me to contemplate the mystery of conscious life perpetuating itself through all eternity, to reflect upon the marvelous structure of the universe which we can dimly perceive, and to try humbly to comprehend even an infinitesimal part of the intelligence manifested in nature.
Luther Burbank
Our lives as we live them are passed on to others, whether in physical or mental forms tinging all future lives forever. This should be enough for one who lives for truth and service to his fellow passengers on the way. No avenging Jewish God, no satanic devil, no fiery hell is of any interest to him. The scientist is a lover of truth for the very love of truth itself, wherever it may lead. Every normal human being has ideals, one or many, to look up to, to reach up to, to grow up to. Religion refers to the sentiments and feelings; science refers to the demonstrated everyday laws of nature. Feelings are all right, if one does not get drunk on them. Prayer may be elevating if combined with works, and they who labor with head, hands, or feet have faith and are generally quite sure of an immediate and favorable reply.
Those who take refuge behind theological barbed wire fences, quite often wish they could have more freedom of thought, but fear the change to the great ocean of scientific truth as they would a cold bath plunge.
Sir Arthur Keith
Certainly the creative power which is at work bears no resemblance to the personal God postulated by the Hebrews, and the modern man of science cannot fit Him into the scheme of the world as he knows it. He has to try to reconceive God, and when he has done so, nothing but an unsatisfying abstraction is left. It is unsatisfying because even the greatest men of science, although they possess the intellects of giants, have still the hearts of children. And children cling to that which is endowed with a human shape and has been given the warmth of living flesh.
H. Levy
A structure of absolute moral and religious beliefs erected initially as beyond criticism, imposed upon a changing society from above rather than emerging from below, has no affinity with science, whatever personal solace and comfort it may provide, for it assumes that the facts of life, including the material facts of the world, can be compassed within a rigidly prescribed framework. It has taken several centuries of history for the scientific movement to be emancipated from just these cramping human assumptions. The writings of many scientists show, alas, that the emancipation has not yet been completed.
J. B. S. Haldane
We know very little about what may be called the geography of the invisible world. The religions, if I may continue the metaphor, have covered the vacant spaces of its map with imaginary monsters; the philosophies have ruled them with equally imaginary parallels of latitude. But both have affirmed, in opposition to the so-called practical man, that the meaning of the visible world is to be found in the invisible. That has been the secret of their success. They have failed when they tried either to describe the details of the visible world or to dictate the details of conduct in it. The churches are half empty today because their creeds are full of obsolete science, and their ethical codes are suited to a social organization far simpler than that of today.
