“It is this mythical, or rather this symbolic, content of the religious traditions which is likely to come into conflict with science. This occurs whenever this religious stock of ideas contains dogmatically fixed statements on subjects which belong in the domain of science. Thus, it is of vital importance for the preservation of true religion that such conflicts be avoided when they arise from subjects which, in fact, are not really essential for the pursuance of the religious aims.”

1920s
Context: It is the natural tendency of the ignorant to believe what is not true. In order to overcome that tendency it is not sufficient to exhibit the true; it is also necessary to expose and denounce the false. To admit that the false has any standing in court, that it ought to be handled gently because millions of morons cherish it and thousands of quacks make their livings propagating it—to admit this, as the more fatuous of the reconcilers of science and religion inevitably do, is to abandon a just cause to its enemies, cravenly and without excuse. It is, of course, quite true that there is a region in which science and religion do not conflict. That is the region of the unknowable.

Physics in my generation (1956)
Context: America has grown by expansion in a practical vacuum; the pioneers of the West had to overcome terrific natural obstacles, but negligible human resistance. The Russia of today had to conquer not only natural but human difficulties: she had to break up the rotten system of the Czars and to assimilate backward Asiatic tribes; now she has set herself the task of bringing her brand of modernization to the ancient civilizations of the Far East. For this purpose it is indispensable to have a well-defined doctrine full of slogans, which appeals to the needs and instincts of the poverty-stricken masses. Thus one understands the power which Marx's philosophy has gained in the East.
What can we scientists do in this conflict? We can join the spiritual, religious, philosophical forces, which reject war on ethical grounds. We can even attack the ideological foundations of the conflict itself. For science is not only the basis of technology but also the material for a sound philosophy.

Indian Spirituality and Life (1919)
Context: Indian religion never considered intellectual or theological conceptions about the supreme Truth to be the one thing of central importance. To pursue that Truth under whatever conception or whatever form, to attain to it by inner experience, to live in it in consciousness, this it held to be the sole thing needful. One school or sect might consider the real self of man to be indivisibly one with the universal Self or the supreme Spirit. Another might regard man as one with the Divine in essence but different from him in Nature. A third might hold God, Nature and the individual soul in man to be three eternally different powers of being. But for all the truth of Self held with equal force; for even to the Indian dualist God is the supreme self and reality in whom and by whom Nature and man live, move and have their being and, if you eliminate God from his view of things, Nature and man would lose for him all their meaning and importance. The Spirit, universal Nature (whether called Maya, Prakriti or Shakti) and the soul in living beings, Jiva, are the three truths which are universally admitted by all the many religious sects and conflicting religious philosophies of India. Universal also is the admission that the discovery of the inner spiritual self in man, the divine soul in him, and some kind of living and uniting contact or absolute unity of the soul in man with God or supreme Self or eternal Brahman is the condition of spiritual perfection. It is open to us to conceive and have experience of the Divine as an impersonal Absolute and Infinite or to approach and know and feel Him as a transcendent and universal sempiternal Person: but whatever be our way of reaching him, the one important truth of spiritual experience is that he is in the heart and centre of all existence and all existence is in him and to find him is the great self-finding.
