There is nothing so disastrous as a rational investment policy in an irrational world. — © John Maynard Keynes
There is nothing so disastrous as a rational investment policy in an irrational world.
In this acausal world, scientists are helpless. Their predictions become postdictions- Their equations become justifications, their logic, illogic. Scientists turn reckless and mutter like gamblers who cannot stop betting. Scientists are buffoons, not because they are rational but because the cosmos is irrational. Or perhaps it is not because the cosmos is irrational but because they are rational. Who can say which, in an acausal world?
It doesn't sound rational for a Klansman to sit down to dinner with a black man. What you're overlooking is, to be racist is to be irrational. So, they are already irrational, and irrational people do irrational things. That's why a Klansman will sit down with me.
... there is no such thing as a rational world and a separate irrational world, but only one world containing both.
I don't think we are all irrational every time we fail to see through an argument in a book, but suppose it's true about you. You are still more rational than you think you are. You are irrational in a minor way - believing a misguided theory of the nature of rationality - but rational in a major way - you respond well to probabilistic evidence as you go through the day.
To the rational being only the irrational is unendurable, but the rational is endurable.
If you simply announce that things are irrational, then that alone doesn't get you very far. You have to replace rational agents with some concrete notion of what it means to be irrational.
Capitalism may even be identical with the restraint, or at least a rational tempering, of this irrational impulse. But capitalism is identical with the restraint, or at least a rational tempering, of this irrational impulse. But capitalism is identical with the pursuit of profit, and forever renewed profit, by means of continuous, rational, capitalistic enterprise.
If you simply announce that things are irrational, then that alone doesnt get you very far. You have to replace rational agents with some concrete notion of what it means to be irrational.
Happiness is a state of non-contradictory joy . . . Happiness is possible only to a rational man, the man who desires nothing but rational goals, seeks nothing but rational values, and finds his joy in nothing but rational actions.
There is nothing in life so irrational, that good sense and chance may not set it to rights; nothing so rational, that folly and chance may not utterly confound it.
I chose the name Pi because it's an irrational number (one with no discernable pattern). Yet scientists use this irrational number to come to a "rational" understanding of the universe. To me, religion is a bit like that, "irrational" yet with it we come together we come to a sound understanding of the universe.
The techniques of kitsch, which are based on imitation, are rational and operate according to formulas; the remain rational even when their result has a highly irrational, even crazy, quality.
The soul has two parts, one rational and the other irrational. Let us now similarly divide the rational part, and let it be assumed that there are two rational faculties, one whereby we contemplate those things whose first principles are invariable, and one whereby we contemplate those things which admit of variation.
There's no evidence whatsoever that men are more rational than women or that men are more willing to surrender their irrational beliefs. Both sexes seem to be equally irrational.
First of all, developed countries have basically expropriated the atmosphere of the world community. But one must say clearly that we redistribute de facto the world's wealth by climate policy. Obviously, the owners of coal and oil will not be enthusiastic about this. One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with environmental policy anymore.
The knowledge of God, the belief in God, is what I call an a-rational process. It's not rational - it doesn't proceed by scientific investigation - but it's not irrational because it doesn't contradict my reasoning process. It goes beyond it.
