“The opinion appears to be gaining ground that this very general conception of functionality, born on mathematical ground, is destined to supersede the narrower notion of causation, traditional in connection with the natural sciences. As an abstract formulation of the idea of determination in its most general sense, the notion of functionality includes and transcends the more special notion of causation as a one-sided determination of future phenomena by means of present conditions; it can be used to express the fact of the subsumption under a general law of past, present, and future alike, in a sequence of phenomena. From this point of view the remark of Huxley that Mathematics "knows nothing of causation" could only be taken to express the whole truth, if by the term "causation" is understood "efficient causation." The latter notion has, however, in recent times been to an increasing extent regarded as just as irrelevant in the natural sciences as it is in Mathematics; the idea of thorough-going determinancy, in accordance with formal law, being thought to be alone significant in either domain.”

"At Large", speech at the Peace Corps twenty-fifth anniversary memorial service (21 September 1986), published in Moyers on Democracy (2008), p. 27<!-- italics in source -->
Context: As every volunteer testifies, the Peace Corps is more than a program or mission. It is a way of being in the world. This is a conservative notion because it holds dear the ground of one's own being — the culture and customs that gave meaning to a particular life. But it is a liberal notion for respecting the ground revered by others. This double helix in America's DNA may yet be the source of a new political and patriotism that could save us from toxic self-absorption.

Source: The Moral Judgment of the Child (1932), Ch. 2 : Adult Constraint and Moral Realism <!-- p. 176 -->
Context: The notion of good, which generally speaking, appears later than the notion of pure duty, particularly in the case of the child, is perhaps the final conscious realization of something that is the primary condition of the moral life — the need for reciprocal affection. And since moral realism is, on the contrary, the result of constraint exercised by the adult on the child, it may perhaps be a secondary growth in comparison to the simple aspiration after good, while still remaining the first notion to be consciously realized when the child begins to reflect upon morality and to attempt formulation.

"From Beyond" Written November 16, 1920, published June 1934 in The Fantasy Fan, 1
Fiction
Context: What do we know … of the world and the universe about us? Our means of receiving impressions are absurdly few, and our notions of surrounding objects infinitely narrow. We see things only as we are constructed to see them, and can gain no idea of their absolute nature. With five feeble senses we pretend to comprehend the boundlessly complex cosmos, yet other beings with wider, stronger, or different range of senses might not only see very differently the things we see, but might see and study whole worlds of matter, energy, and life which lie close at hand yet can never be detected with the senses we have.

Lecture I, "Religion and Neurology"
1900s, The Varieties of Religious Experience (1902)
Context: To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor's body at the time.
