“For, to my mind, this is a certain principle, that nothing is here treated of but the visible form of the world. He who would learn astronomy, and other recondite arts, let him go elsewhere.(on commenting the text of Genesis 1:6)”

“I would urge us to be not too certain of our accustomed ways of looking at Genesis, and to open ourselves to the wisdom of the God-bearing men of the past who have devoted so much intellectual effort to understanding the text of Genesis as it was meant to be understood. These Holy Fathers are our key to understanding Genesis.”

“If an Elder shall give us a lecture upon astronomy, chemistry, or geology, our religion embraces it all. It matters not what the subject be, if it tends to improve the mind, exalt the feelings, and enlarge the capacity. The truth that is in all the arts and sciences forms part of our religion. Faith is no more a part of it than any other true principle of philosophy.”

“What he was after hangs between the visible and the invisible, between the here and now and the seemingly elsewhere.”

“Let the tutor make his charge pass everything through a sieve and lodge nothing in his head on mere authority and trust: let not Aristotle's principles be principles to him any more than those of the Stoics or Epicureans. Let this variety of ideas be set before him; he will choose if he can; if not, he will remain in doubt. Only the fools are certain and assured. For if he embraces Xenophon's and Plato's opinions by his own reasoning, they will no longer be theirs, they will be his. He who follows another follows nothing. He finds nothing; indeed he seeks nothing. We are not under a king; let each one claim his own freedom. Let him know that he knows, at least. He must imbibe their ways of thinking, not learn their precepts. And let him boldly forget, if he wants, where he got them, but let him know how to make them his own. Truth and reason are common to everyone, and no more belong to the man who first spoke them than to the man who says them later. It is no more according to Plato than according to me, since he and I understand and see it the same way. The bees plunder the flowers here and there, but afterward they make of them honey, which is all theirs; it is no longer thyme or marjoram. Even so with the pieces borrowed from others; he will transform and blend them to make a work of his own, to wit, his judgment. His education, work, and study aim only at forming this.”

“Principles of design:1. Use both knowledge in the world and knowledge in the head.2. Simplify the structure of tasks.3. Make things visible: bridge gulfs between Execution and Evaluation.4. Get the mappings right.5. Exploit the power of constraints.6. Design for error.7. When all else fails, standardize.”
