Take practical and rational steps in maximizing your time

That which does not come by logic, does not leave by logic.

The Apparent is the Bridge to the Real

The best way to destroy the decrepit is to build the glorious.

The difficulty is that, so long as unreason prevails, a solution of our troubles can only be reached by chance; for while reason, being impersonal, makes universal co-operation possible, unreason, since it represents private passions, makes strife inevitable. It is for this reason that rationality, in the sense of an appeal to a universal and impersonal standard of truth, is of supreme importance to the well-being of the human species.

The educated don't get that way by memorizing facts; they get that way by respecting them.

The duty and the responsibility of a rationalist is to thoughtfully and promptly carry out his actions, in fraternal affection, without considering country, language, God, religion and caste.

The fact is you cannot be intelligent merely by choosing your opinions. The intelligent man is not the man who holds such-and-such views but the man who has sound reasons for what he believes and yet does not believe it dogmatically. And opinions held for sound reasons have less emotional unity than the opinions of dogmatists because reason is non-party, favouring now one side and now another. That is what people find so unpleasant about it.

The essence of extended rationality is to know when you are being irrational.

The goal of argumentation is to make a case so forceful (note the metaphor) that skeptics are coerced into believing it—they are powerless to deny it while still claiming to be rational. In principle, it is the ideas themselves that are, as we say, compelling, but their champions are not always averse to helping the ideas along with tactics of verbal dominance, among them intimidation (“Clearly . . .”), threat (“It would be unscientific to . . .”), authority (“As Popper showed . . .”), insult (“This work lacks the necessary rigor for . . .”), and belittling (“Few people today seriously believe that . . .”). Perhaps this is why H. L. Mencken wrote that “college football would be more interesting if the faculty played instead of the students.

The fundamental difference between ideology and science is that the former asserts what you or someone else would prefer to hear, and the second about what is plausible in his vision, without taking this preference into account. Ideology can never be more than a subjective value judgment, while science must be free from that judgment. Ideology is intended for the masses, who have little or no rational and analytical thinking, science - for intellectuals, for whom this thinking is the main value. The masses will never be able to do genuine science, because no true intellectual can be an ideologue, because any ideological assumption will deprive him of his rational and analytical thinking or significantly reduce it. Free rational thinking based on empirical scientific facts often forces you to go against various common forms of ideology, such as history and religion.

The good parts of our relationship felt like a rat walking around and gnawing at the inside of my stomach.

The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life. This project is ambitious but technically feasible. It is also instrumentally rational and ethically mandatory. The metabolic pathways of pain and malaise evolved only because they once served the fitness of our genes. They will be replaced by a different sort of neural architecture. States of sublime well-being are destined to become the genetically pre-programmed norm of mental health. The world's last aversive experience will be a precisely dateable event.

The human has not one but two births – first, when a person is born from the mother’s womb, and second, when that person rises from the socio-culturally imposed cocoon of prejudices and ignorance.

The joy from eating does not come from the exclusivity of the food, but instead from the sensitivity that we eat it with.

The idea of our own rationality...was convincing to us only because we so wished to be convinced. To any impartial observer, could such a thing exist, the sham was patent. Emotion and instinct were the basis of all our decisions, our actions, everything we valued, the way we saw the world. Reason and rationality were a thin coat of paint on a ragged surface.

The methods of increasing the degree of truth in our beliefs are well known; they consist in hearing all sides, trying to ascertain all the relevant facts, controlling our own bias by discussion with people who have the opposite bias, and cultivating a readiness to discard any hypothesis which has proved inadequate.

The mind of the most rational among us may be compared to a stormy ocean of passionate convictions based on desire, upon which float perilously a few tiny boats carrying a cargo of scientifically tested beliefs.

The less evidence we have for what we believe is certain, the more violently we defend beliefs against those who don't agree.

Then are there no rules at all, Lord?” Moneo's voice conveyed a faint hint of hysteria. Leto smiled to ease the man's tensions. “Perhaps one. Short–term decisions tend to fail in the long–term.

The most flattering spin I can put on this phase of paradoxes and metaphysical tangles is that I was smart enough, at age fourteen, to destroy any fledgling hypothesis I came up with. A tentative explanation, theory, or formulation would pop up in my brain only to be attacked by what amounted to a kind of logical immune system, bent on eliminating all that was weak or defective. Which is to say that my mind had become a scene of furious predation, littered with the half-eaten corpses of vast theories and brilliant syntheses.

The more rational we are, the more emotional we can be.

The most damaging cognitive bias is overconfidence (illusory superiority), making leaders use their “gut” when they should be more rational.

The New Man means to develop all the three dimensions of being, all the three doors to God: the head, the dimension of thinking, logic and reason, the heart - the dimension of joy, trust, intuition, relationships, beauty, creativity and a sense of unity in love and the being, the dimension of meditation, silence, emptiness and oneness with life. The first level of the head is the dimension of ideas, intellect, hypothesis, theories, logic, analysis, rationality and dualistic thinking. The first level is the level of the mind, which means a continuous oscillation like a pendulum between the mind's memories of the past and the ideas, dreams and expectations of the future. The second level of the heart is the dimension of joy, acceptance, trust, understanding, trust, friendship, intuition, empathy, creativity, compassion, humor, playfulness and a sense of unity in love. The third level of being is the dimension of presence, awareness, meditation, silence, emptiness and wholeness. The third level is our connection with our inner life source.

Then you get the wrong answer and you can't go to the Moon that way! Nature isn't a person, you can't trick them into believing something else, if you try to tell the Moon it's made of cheese you can argue for days and it won't change the Moon! What you're talking about is rationalization, like starting with a sheet of paper, moving straight down to the bottom line, using ink to write 'and therefore, the Moon is made of cheese', and then moving back up to write all sorts of clever arguments above. But either the Moon is made of cheese or it isn't. The moment you wrote the bottom line, it was already true or already false. Whether or not the whole sheet of paper ends up with the right conclusion or the wrong conclusion is fixed the instant you write down the bottom line.

The point we are trying to make is that disagreement is futile agitation unless it is undertaken with the hope that it may lead to the resolution of an issue. These two facts, that people do disagree and can agree, arise from the complexity of human nature. Men are rational animals. Their rationality is the source of their power to agree. Their animality, and the imperfections of their reason that it entails, is the cause of most of the disagreements that occur. Men are creatures of passion and prejudice. (P. 146)

The point is that if you think you can pinpoint the cause, then you can fool yourself into thinking you can avert the cause. It's deeply egotistical. It's life played as a grand insurance policy. Our myth-making around cancer stems from the same impulse. Because we don't know exactly why most of it happens, we weave a makeshift wisdom around it, a false prophet, which seeps into the common story and feeds our hunger to understand why. The guilt is a byproduct, a way to assign blame and seek absolution. It's a lesser evil than the forces of randomness. And it gives us the illusion of control.

The only kind of appeal that wins any instinctive response in party politics is an appeal to hostile feeling; the men who perceive the need of cooperation are powerless. Until education has been directed for a generation into new channels, and the Press has abandoned incitements to hatred, only harmful policies have any chance of being adopted in practice by our present political methods. But there is no obvious means of altering education and the Press until our political system is altered. From this dilemma there is no issue by means of ordinary action, at any rate for a long time to come. The best that can be hoped, it seems to me, is that we should, as many of us as possible, become political skeptics, rigidly abstaining from belief in the various attractive party programmes that are put before us from time to time.

The reader who thinks that rationality does not require a definition should ponder the following: I'll give you a million dollars to do something irrational.

The power of reason is thought small in these days, but I remain an unrepentant rationalist. Reason may be a small force, but it is constant, and works always in one direction, while the forces of unreason destroy one another in futile strife. Therefore every orgy of unreason in the end strengthens the friends of reason, and shows afresh that they are the only true friends of humanity.

The practice which obtains amongst the Americans of fixing the standard of their judgment in themselves alone, leads them to other habits of mind. As they perceive that they succeed in resolving without assistance all the little difficulties which their practical life presents, they readily conclude that everything in the world may be explained, and that nothing in it transcends the limits of the understanding. Thus they fall to denying what they cannot comprehend; which leaves them but little faith for whatever is extraordinary, and an almost insurmountable distaste for whatever is supernatural.

There's a whole [...] art to finding the truth and accomplishing value from inside a human mind: we have to learn our own flaws, overcome our biases, prevent ourselves from self-deceiving, get ourselves into good emotional shape to confront the truth and do what needs doing, etcetera etcetera and so on.

There is no history of mankind, there is only an indefinite number of histories of all kinds of aspects of human life. And one of these is the history of political power. This is elevated into the history of the world. But this, I hold, is an offence against every decent conception of mankind. It is hardly better than to treat the history of embezzlement or of robbery or of poisoning as the history of mankind. For the history of power politics is nothing but the history of international crime and mass murder.

There is voluminous evidence that exclusive reliance on heuristic processing tendencies of Type I sometimes results in suboptimal responding (Baron, 2008; Evans, 2007a; Gilovich, Griffin, & Kahneman, 2002; Johnson-Laird, 2006; Kahneman & Tversky, 1973, 1996, 2000; Koehler & Harvey, 2004; Nickerson, 2004, 2008; Nisbett & Ross, 1980; Tversky & Kahneman, 1974, 1983, 1986) and that such thinking errors are not limited to the laboratory (Ariely, 2008; Åstebro, Jeffrey, & Adomdza, 2007; Baron, 1998; Baron, Bazerman, & Shonk, 2006; Belsky & Gilovich, 1999; Berner & Graber, 2008; Camerer, 2000; Chapman & Elstein, 2000; Croskerry, 2009a, 2009b; Dawes, 2001; Hilton, 2003; Kahneman & Tversky, 2000; Lichtenstein & Slovic, 2006; Lilienfeld, Ammirati, & Landfield, 2009; Myers, 2002; Prentice, 2003; Reyna et al., 2009; Stewart, 2009; Sunstein, 2002, 2005; Taleb, 2001, 2007; Tavris & Aronson, 2007; Tetlock, 2005; Thaler & Sunstein, 2008; Ubel, 2000).

There's great peace in surrendering to principles

The type of journalism that relies on the reporter's notion of what does or doesn't "seem" correct or controversial is self-indulgent and irresponsible. It gives credence to the belief that we can intuit our way through all the various decisions we need to make in our lives and it validates the notion that our feelings are a more reliable barometer of reality than the facts.

The root of liberalism, in a word, is hatred of compulsion, for liberalism has the respect for the individual and his conscience and reason which the employment of coercion necessarily destroys. The liberal has faith in the individual – faith that he can be persuaded by rational means to beliefs compatible with social good.

the thing about fear is that it defies the laws of rationality. It creates its own laws instead

The truly rational thing is not to reason, but to follow one's instincts.

The unthinking embrace of irrationality is literally madness. But embracing rationality while denying the existence of any mystery to life and its meaning — that is no less a form of madness than is eager devotion to unreason.

The Use of the Understanding, in endeavouring to find out the Meaning of any Proposition whatsoever, in considering the nature and Evidence for or against it, and in judging of it according to the seeming Force or Weakness of the Evidence.

The way most people use their minds is analogous to an ambulance that is used only as an umbrella.

The Way of Bayes is also an imprecise art, at least the way I'm holding forth upon it. These blog posts are still fumbling attempts to put into words lessons that would be better taught by experience. But at least there's underlying math, plus experimental evidence from cognitive psychology on how humans actually think. Maybe that will be enough to cross the stratospherically high threshold required for a discipline that lets you actually get it right, instead of just constraining you into interesting new mistakes.

The sexual mechanisms of the two genders are just not compatible, that’s the horrible truth of it. (...) This is a truth we dare not acknowledge these days - because sameness is our religion and heretics are no more welcome now than they ever were - but I’m going to acknowledge it, because I’ve always felt that humility before the facts is the only thing that keeps a rational man together. Be humble in the face of facts, and proud in the face of opinions, as George Bernard Shaw once said. He didn’t, actually. I just wanted to put some authority behind this observation of mine, because I know you’re not going to like it.

The true self is that which is in touch with reality. The false self is the aspects of your personality that are adapted to threats and no longer consciously recognizes either the adaptation or the threat.

The world,” he said, “grows hourly more and more sceptical of all that lies beyond its own narrow radius; and our men of science foster the fatal tendency. "The Phantom Coach

The world is too much for us. Rationality as we have come to know it works by ignoring most of experience: laws are arrived at by selective abstraction.

To evade insanity and depression, we unconsciously limit the number of people toward whom we are sincerely sympathetic.

The worst thing about logic - it is not democratic. Logic wears an autocratic mask. No compromises are made there for things are binary. Only intellectual standards democratise it to make it human. That is why you joined rationality with character. Rationality is autocratic - what is wrong does not live for long. Wrong facts, theories, and conclusions die - useless to apply in spite of their unlimited supply.

This mundus tenebrosus, this shaddowy world of Mankind, is sunk into Night; there is not a Field without its Spirits, nor a City without its Daemons, and the Lunaticks speak Prophesies while the Wise men fall into the Pitte. We are all in the Dark, one with another. And, as the Inke stains the Paper on which it is spilt and slowly spreads to Blot out the Characters, so the Contagion of darkness and malefaction grows apace until all becomes unrecognizable. Thus it was with the Witches who were tryed by Swimming not long before, since once the Prosecution had commenced no Stop could be put to the raving Women who came forward: the number of Afflicted and Accused began to encrease and, upon Examination, more confess'd themselves guilty of Crimes than were suspected of. And so it went, till the Evil revealed was so great that it threatened to bring all into Confusion. And yet in the way of that Philosophie much cryed up in London and elsewhere, there are those like Sir Chris. who speak only of what is Rational and what is Demonstrated, of Propriety and Plainness. Religion Not Mysterious is their Motto, but if they would wish the Godhead to be Reasonable why was it that when Adam heard that Voice in the Garden he was afraid unto Death? The Mysteries must become easy and familiar, it is said, and it has now reached such a Pitch that there are those who wish to bring their mathematicall Calculations into Morality, viz. the Quantity of Publick Good produced by any Agent is a compound Ratio of his Benevolence and Abilities, and such like Excrement. They build Edifices which they call Systems by laying their Foundacions in the Air and, when they think they are come to sollid Ground, the Building disappears and the Architects tumble down from the Clowds. Men that are fixed upon matter, experiment, secondary causes and the like have forgot there is such a thing in the World which they cannot see nor touch nor measure: it is the Praecipice into which they will surely fall.
