Brain Size Quotes

When brains get sufficiently big, presumably, as human brains have, consciousness seems to emerge.

It may be quite true that some negroes are better than some white men; but no rational man, cognisant of the facts, believes that the average negro is the equal, still less the superior, of the average white man. And, if this be true, it is simply incredible that, when all his disabilities are removed, and our prognathous relative has a fair field and no favour, as well as no oppressor, he will be able to compete successfully with his bigger-brained and smaller-jawed rival, in a contest which is to be carried on by thoughts and not by bites.

The capacity of the crania of the Mongol, Indian and Negro, and all dark skinned races, is smaller than that of the pure white man.

It has actually been suggested that warfare may have been the principle evolutionary pressure that created the huge gap between the human brain and that of our closest living relatives, the anthropoid apes. Whole groups of hominids with inferior brains could not win wars and were therefore exterminated.

An individual ant, even though it has a brain about a millionth of a size of a human being's, can learn a maze; the kind we use is a simple rat maze in a laboratory. They can learn it about one-half as fast as a rat.

In proportion to our body mass, our brain is three times as large as that of our nearest relatives. This huge organ is dangerous and painful to give birth to, expensive to build and, in a resting human, uses about 20 per cent of the body's energy even though it is just 2 per cent of the body's weight. There must be some reason for all this evolutionary expense.

We admit, in geometry, not only infinite magnitudes, that is to say, magnitudes greater than any assignable magnitude, but infinite magnitudes infinitely greater, the one than the other. This astonishes our dimension of brains, which is only about six inches long, five broad, and six in depth, in the largest heads.

We cannot experimentally map out the brain. It's just too big. In a piece of the brain the size of a pinhead there are 3,000 pathways like a city with 3,000 streets.

When it comes to brains, size matters. It's not all that matters, of course. Whales and dolphins have brains that are larger than humans', but few of the flippered and fluked set win tenure at Stanford. Our brains are the largest in proportion to body size, and they're also highly sophisticated.

We are permitted to suppose that the relatively small size of the female brain depends in part upon her physical inferiority and in part upon her intellectual inferiority.

You can build a brain the size of a room, theoretically. You could also build a silicone based life form and it could be sentient. There's no limit to the height that you can reach in terms of design once we figure out how to design things, theoretically.

Knowledge fills a large brain; it merely inflates a small one.

I am 5ft 6in and weigh about 11 stone - about a stone overweight, but that's because of my brain.

But it was pointless, it was stupid; he thought about thoughtless things. If I were a seabird . . . but how could you be a seabird? If you were a seabird your brain would be tiny and stupid and you would love half-rotted fish guts and tweaking the eyes out of little grazing animals; you would know no poetry and you could never appreciate flying as fully as the human on the ground yearning to be you. If you wanted to be a seabird you deserved to be one.

Some of us are sixty feet long with a brain the size of a walnut.

There are brains so large that they unconsciously swamp all individualities ties which come in contact or too near, and brains so small that they cannot take in the conception of any other individuality as a whole, only in part or parts.

If language naturally evolves to serve the needs of tiny rodents with tiny rodent brains, then what's unique about language isn't the brilliant humans who invented it to communicate high-level abstract thoughts. What's unique about language is that the creatures who develop it are highly vulnerable to being eaten.

When I fish, I stop thinking about anything else. But truth be told, if you want to declare victories, I can tell you the fish have won a lot more than I have. It's interesting that something with a brain the size of a fish's can outsmart us humans, who think we are el supremo.

Certainly the first true humans were unique by virtue of their large brains. It was because the human brain is so large when compared with that of a chimpanzee that paleontologists for years hunted for a half-ape, half-human skeleton that would provide a fossil link between the human and the ape.

I have little hair because my brain is so big it pushes the hair out.

A fly with a brain the size of a salt grain has the behavioral repertoire nearly as complex as a much larger animal such as a mouse. That's a super-interesting problem from an engineering perspective.

It is certain that there may be extraordinary mental activity with an extremely small absolute mass of nervous matter: thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head. Under this point of view, the brain of an ant is one of the most marvelous atoms of matter in the world, perhaps more so than the brain of a man.

Absolute brain size does not tell you everything or possibly sometimes even much. Elephants and whales both have brains larger than ours, but you wouldn't have much trouble outwitting them in contract negotiations.

You want to talk? Fine. Talk. Tell me something you've never told anybody else.' I thought for a moment. 'Turtles have the second-largest brains of any animal on the planet.' It took Isabel only a second to process this. 'No, they don't.' 'I know that's why I've never told anybody that before.

Wrangham cites several studies indicating that in fact humans don't do well on raw food: they can't maintain their body weight, and half of the women on a raw-food regimen stop menstruating. Devotees of raw food rely heavily on juicers and blenders, because otherwise they would have to spend as much time chewing as the chimps do. It is difficult, if not impossible, to extract sufficient energy from unprocessed plant matter to power a body with such a big, hungry brain.
