Cognitive Limitations Quotes

We know too much for one man to know too much.

Our knowledge can only be finite, while our ignorance must necessarily be infinite.

We know more than we can tell.

A stupid person can make only certain, limited types of errors; the mistakes open to a clever fellow are far broader. But to the one who knows how smart he is compared to everyone else, the possibilities for true idiocy are boundless.

Dogs have not the power of comparing. A dog will take a small piece of meat as readily as a large, when both are before him.

Far from being the smartest possible biological species, we are probably better thought of as the stupidest possible biological species capable of starting a technological civilization - a niche we filled because we got there first, not because we are in any sense optimally adapted to it.

Evolution has ensured that our brains just aren't equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it's just as easy to think in 11 dimensions, as it is to think in three or four.

The receptivity of the masses is very limited, their intelligence is small, but their power of forgetting is enormous. In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.

Man is the Reasoning Animal. Such is the claim. I think it is open to dispute. Indeed, my experiments have proven to me that he is the Unreasoning Animal... In truth, man is incurably foolish. Simple things which the other animals easily learn, he is incapable of learning. Among my experiments was this. In an hour I taught a cat and a dog to be friends. I put them in a cage. In another hour I taught them to be friends with a rabbit. In the course of two days I was able to add a fox, a goose, a squirrel and some doves. Finally a monkey. They lived together in peace; even affectionately.

The sad thing about true stupidity is that you can do absolutely nothing about it.

While one man can discover a certain thing by himself, another is never able to understand it, even if taught by means of all possible expressions and metaphors, and during a long period; his mind can in no way grasp it, his capacity is insufficient for it.

It is never possible to understand completely any other human being; and no individual will ever really understand himself - the complexity is too great and there is not the time to constantly take things apart and examine them.

If a person cannot foresee the consequences of his act, and is not capable of understanding what he is told about its outcome by those with more experience, it is impossible for him to guide his act intelligently. In such a state, every act is alike to him.

Logic: The art of thinking and reasoning in strict accordance with the limitations and incapacities of the human misunderstanding.

Chimps can do all sorts of things we thought that only we could do - like tool-making and abstraction and generalisation. They can learn a language - sign language - and they can use the signs. But when you think of our intellects, even the brightest chimp looks like a very small child.

No one … can entirely step out of his time, that despite his keenness of vision his thinking is in many ways bound to be influenced by the mentality of his time

Remember that we can only in our forebrains handle 5-7 items. Our backbrains can handle massive amounts. So when you're given a problem, think about it before you go sleep, and chances are you can solve it by the next morning.

Man is so intelligent that he feels impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic.

Knowledge is boundless,--human capacity, limited.

I could play everything but could never take a lead. My brain just doesn't work like that.

Of all the intellectual faculties, judgment is the last to mature. A child under the age of fifteen should confine its attention either to subjects like mathematics, in which errors of judgment are impossible, or to subjects in which they are not very dangerous, like languages, natural science, history, etc.

The greatest intelligence is precisely the one that suffers the most from its own limitations.

Sure, our three-pound brains might be inadequate to understand the universe. But perhaps they're just good enough to build something that can.

If God has created the world, his primary worry was certainly not to make its understanding easy for us

Some people do not become thinkers simply because their memories are too good.
