“It would be very difficult to formulate a position in which there were no external relations. I cannot imagine any structure being defined as though it only has internal meaning.”

1960s, Freedom From The Known (1969)
Context: It is important to understand from the very beginning that I am not formulating any philosophy or any theological structure of ideas or theological concepts. It seems to me that all ideologies are utterly idiotic. What is important is not a philosophy of life but to observe what is actually taking place in our daily life, inwardly and outwardly. If you observe very closely what is taking place and examine it, you will see that it is based on an intellectual conception, and the intellect is not the whole field of existence; it is a fragment, and a fragment, however cleverly put together, however ancient and traditional, is still a small part of existence whereas we have to deal with the totality of life.

1960s, The Quest for Peace and Justice (1964)
Context: Every man lives in two realms, the internal and the external. The internal is that realm of spiritual ends expressed in art, literature, morals, and religion. The external is that complex of devices, techniques, mechanisms, and instrumentalities by means of which we live. Our problem today is that we have allowed the internal to become lost in the external. We have allowed the means by which we live to outdistance the ends for which we live. So much of modern life can be summarized in that arresting dictum of the poet Thoreau: "Improved means to an unimproved end". This is the serious predicament, the deep and haunting problem confronting modern man. If we are to survive today, our moral and spiritual "lag" must be eliminated. Enlarged material powers spell enlarged peril if there is not proportionate growth of the soul. When the "without" of man's nature subjugates the "within", dark storm clouds begin to form in the world.

Physics and Philosophy (1958)
Context: The words "position" and "velocity" of an electron... seemed perfectly well defined... and in fact they were clearly defined concepts within the mathematical framework of Newtonian mechanics. But actually they were not well defined, as seen from the relations of uncertainty. One may say that regarding their position in Newtonian mechanics they were well defined, but in their relation to nature, they were not. This shows that we can never know beforehand which limitations will be put on the applicability of certain concepts by the extension of our knowledge into the remote parts of nature, into which we can only penetrate with the most elaborate tools. Therefore, in the process of penetration we are bound sometimes to use our concepts in a way which is not justified and which carries no meaning. Insistence on the postulate of complete logical clarification would make science impossible. We are reminded... of the old wisdom that one who insists on never uttering an error must remain silent.
