“The advice takes the form of four simple suggestions for how to do well in a durable iterated Prisoner's Dilemma:1. Don't be envious.
2. Don't be the first to defect.
3. Reciprocate both cooperation and defection.
4. Don't be too clever.”

“Whenever I face a hard decision or a risky situation in life (personally or professionally), all my thinking, all my analysis, all my planning can be boiled down to four simple questions:
1. What is the best thing that can happen if I do this?
2. What is the worst thing that can happen if I do this?
3. What is the best thing that can happen if I don't do it?
4. What is the worst thing that can happen if I don't do it?”

“First, the eight rules of tolerance: 1. Stay out of the way. 2. Don't pick a fight. 3. If challenged, walk away. 4. Avoid eye contact. 5. If your enemy is diurnal, learn to be nocturnal. 6. Vice versa. 7. Possess nothing the other wants. 8. Draw the line at hurting kids: I will fight to the death.
After tolerance is achieved comes play. Here are the nine rules of play: 1. Know when to quit. 2. Learn how to handicap. 3. Learn what frightens the other (cat claws). 4. Don't let it get to you. It's just a game; you mustn't take it seriously (cats have trouble with this one—escalation is always a risk in cat games). 5. Don't eat your playmate. 6. Pay attention to the signals on the other side—for instance, “enough” and “quit.” 7. Don't suddenly change the rules. 8. Don't be a sore loser. 9. Remember: It's only a game.
And if play succeeds, we can move on to the eight rules of friendship: 1. Learn the rules of your opposite number. 2. Recognize that danger is no longer relevant. 3. Take your time. 4. One step at a time. 5. Apologize often by learning the other's words, gestures, sounds, or postures for “I'm sorry.””

Jeffrey Moussaieff Masson (1941) American writer and activist

6. Acknowledge mistakes. 7. Make the offer of friendship more than once. 8. Express curiosity about what the other is like.

“All the light which is radiated… will, after it has traveled a distance r, lie on the surface of a sphere whose area S is given by the first of the formulae (3). And since the practical procedure… in determining d is equivalent to assuming that all this light lies on the surface of a Euclidean sphere of radius d, it follows…4 \pi d^2 = S = 4 \pi r^2 (1 - \frac{K r^2}{3} + …);whence, to our approximation 4)d = r (1- \frac{K r^2}{6} + …), or
r = d (1 + \frac{K d^2}{6} + …).</center”

“According to Taylor, the principles of Efficiency are:
(1) Science, not rule of thumb.
(2) Harmony, not discord.
(3) Cooperation, not competition.
(4) Maximum output, not restricted output.
(5) The development of each man to his greatest efficiency and prosperity.”

“The Rule of Three, or Golden Rule of Arithmeticall whole Numbers. Be the three termes given 2 3 4. …To finde their fourth proporcionall Terme: that is to say, in such Reason to the third terme 4, as the second terme 3, is to the first terme 2 [Modern notation: \frac{x}{4} = \frac{3}{2}]. …Multiply the second terme 3, by the third terme 4, & giveth the product 12: which dividing by the first terme 2, giveth the Quotient 6: I say that 6 is the fourth proportional terme required.”

Rule 1: Don't do it.
Rule 2 (for experts only). Don't do it yet - that is, not until you have a perfectly clear and unoptimized solution.”

“In the course of describing my formative moment in 1978, I have already implicitly given my four basic rules for research. Let me now state them explicitly, then explain. Here are the rules:1. Listen to the Gentiles
2. Question the question
3. Dare to be silly
4. Simplify, simplify”
