“If nature has offered to produce the maximum effect with minimum causes, it is in all of its laws that it had to solve this major problem.”

1970s, The Humble Programmer (1972)

Context: All the greatest mathematicians have long since recognized that the method presented in this book is not only extremely useful in analysis, but that it also contributes greatly to the solution of physical problems. For since the fabric of the universe is most perfect, and is the work of a most wise Creator, nothing whatsoever takes place in the universe in which some relation of maximum and minimum does not appear. Wherefore there is absolutely no doubt that every effect in the universe can be explained as satisfactorily from final causes, by the aid of the method of maxima and minima, as it can from the effective causes themselves. Now there exist on every hand such notable instances of this fact, that, in order to prove its truth, we have no need at all of a number of examples; nay rather one's task should be this, namely, in any field of Natural Science whatsoever to study that quantity which takes on a maximum or a minimum value, an occupation that seems to belong to philosophy rather than to mathematics. Since, therefore, two methods of studying effects in Nature lie open to us, one by means of effective causes, which is commonly called the direct method, the other by means of final causes, the mathematician uses each with equal success. Of course, when the effective causes are too obscure, but the final causes are more readily ascertained, the problem is commonly solved by the indirect method; on the contrary, however, the direct method is employed whenever it is possible to determine the effect from the effective causes. But one ought to make a special effort to see that both ways of approach to the solution of the problem be laid open; for thus not only is one solution greatly strengthened by the other, but, more than that, from the agreement between the two solutions we secure the very highest satisfaction.

Context: Reason, when it is refined into logic, has something to offer but only in terms of itself and depends for its effect and use on the nature of the premise. That useful argument as to how many angels can stand on the point of a needle would turn into nothing without the concept of angels. I took a further step into my new world. I formulated what I had felt against a mass of reasonable evidence and saw that to explain the near infinite mysteries of life by scholastic Darwinism, by the doctrine of natural selection, was like looking at a sunset and saying "Someone has struck a match". As for Freud, the reductionism of his system made me remember the refrain out of Marianna in Moated Grande — "He cometh not, she said, she said I am aweary aweary, O God that I were dead!". This was my mind, not his, and I had a right to it....
We question free will, doubt it, dismiss it, experience it. We declare our own triviality on a small speck of dirt circling a small star at the rim of one countless galaxies and ignore the heroic insolence of the declaration. We have diminished the world of God and man in a universe ablaze with all the glories that contradict that diminution.
Of man and God. We have come to it, have we not? I believe in God; and you may think to yourselves — here is a man who has left a procession and gone off by himself only to end with another gasfilled image he towns round with him at the end of the rope. You would be right of course. I suffer those varying levels or intensities of belief which are, it seems, the human condition. Despite the letters I still get from people who believe me to be still alive and who are deceived by the air of confident authority that seems to stand behind that first book, Lord of the Flies, nevertheless like everyone else I have had to rely on memories of moments, bet on what once seemed a certainty but may now be an outsider, remember in faith what I cannot recreate.

Context: There are many creeds but only one faith. Creeds may change, develop, and grow flat, while the substance of faith remains the same in all ages. The overgrowth of creed may bring about the disintegration of that substance. The proper relation is a minimum of creed and a maximum of faith.
