“If reverence for personality, the principle of mutuality, active goodwill, and love toward God and man constitute the essence of high religion, then in many situations, in an imperfect world, compulsion becomes a religious obligation.”

1920s, The Aims of Education (1929)
Context: The essence of education is that it be religious. Pray, what is religious education? A religious education is an education which inculcates duty and reverence. Duty arises from our potential control over the course of events. Where attainable knowledge could have changed the issue, ignorance has the guilt of vice. And the foundation of reverence is this perception, that the present holds within itself the complete sum of existence, backwards and forwards, that whole amplitude of time, which is eternity.

“The Religion of Life” (1858)

1940s, Religion and Science: Irreconcilable? (1948)
Context: Science, in the immediate, produces knowledge and, indirectly, means of action. It leads to methodical action if definite goals are set up in advance. For the function of setting up goals and passing statements of value transcends its domain. While it is true that science, to the extent of its grasp of causative connections, may reach important conclusions as to the compatibility and incompatibility of goals and evaluations, the independent and fundamental definitions regarding goals and values remain beyond science's reach.
As regards religion, on the other hand, one is generally agreed that it deals with goals and evaluations and, in general, with the emotional foundation of human thinking and acting, as far as these are not predetermined by the inalterable hereditary disposition of the human species. Religion is concerned with man's attitude toward nature at large, with the establishing of ideals for the individual and communal life, and with mutual human relationship. These ideals religion attempts to attain by exerting an educational influence on tradition and through the development and promulgation of certain easily accessible thoughts and narratives (epics and myths) which are apt to influence evaluation and action along the lines of the accepted ideals.

The Ballot or the Bullet (1964), Speech in Detroit, Michigan (12 April 1964)
Context: Islam is my religion, but I believe my religion is my personal business. It governs my personal life, my personal morals. And my religious philosophy is personal between me and the God in whom I believe; just as the religious philosophy of these others is between them and the God in whom they believe. And this is best this way. Were we to come out here discussing religion, we’d have too many differences from the outstart and we could never get together. [... ] If we bring up religion, we’ll be in an argument, and the best way to keep away from arguments and differences, as I said earlier, put your religion at home in the closet. Keep it between you and your God. Because if it hasn’t done anything more for you than it has, you need to forget it anyway.
