Each little update - each individual bit of social information - is insignificant on its own, even supremely mundane. But taken together, over time, the little snippets coalesce into a surprisingly sophisticated portrait of your friends’ and family members’ lives, like thousands of dots making a pointillist painting.
We are a biological species arising from Earth’s biosphere as one adapted species among many; and however splendid our languages and cultures, however rich and subtle our minds, however vast our creative powers, the mental process is the product of a brain shaped by the hammer of natural selection upon the anvil of nature.
The well-being of a neuron depends on its ability to communicate with other neurons. Studies have shown that electrical and chemical stimulation from both a neuron's inputs and its targets support vital cellular processes. Neurons unable to connect effectively with other neurons atrophy. Useless, an abandoned neuron will die.
You say that it is time to shake off the Mist, but Mankind walks in a Mist; that Reason which you cry up as the Glory of this Age is a Proteus and Cameleon that changes its Shape almost in every Man: there is no Folly that may not have a thousand Reasons produc'd to advance it into the Class of Wisdom. Reason itself is a Mist.
Remember that [scientific thought] is the guide of action; that the truth which it arrives at is not that which we can ideally contemplate without error, but that which we may act upon without fear; and you cannot fail to see that scientific thought is not an accompaniment or condition of human progress, but human progress itself.
He leaned into Le Voir’s face with the calliper and breathed on him, holding forth on this new science of which calibration was the test; these measurements would describe classes of being and we who had provided the parameters would be fit within them. To hear him tell it, this classification of species was the hope of Man.
The view is often defended that sciences should be built up on clear and sharply defined basal concepts. In actual fact no science, not even the most exact, begins with such definitions. The true beginning of scientific activity consists rather in describing phenomena and then in proceeding to group, classify and correlate them.
The science, the art, the jurisprudence, the chief political and social theories, of the modern world have grown out of Greece and Rome—not by favour of, but in the teeth of, the fundamental teachings of early Christianity, to which science, art, and any serious occupation with the things of this world were alike despicable.
Si noti il meraviglioso «Mi sembra...» iniziale, che ricorda l’«Io penso...» con cui Darwin introduce nei suoi taccuini la grande idea che le specie evolvono, o l’«esitazione» di cui parla Faraday quando nel suo libro introduce la rivoluzionaria idea di campo elettrico. Il genio esita.
When the wrong question is being asked, it usually turns out to be because the right question is too difficult. Scientists ask questions they can answer. That is, it is often the case that the operations of a science are not a consequence of the problematic of that science, but that the problematic is induced by the available means.
The tendency has always been strong to believe that whatever received a name must be an entity or being, having an independent existence of its own. And if no real entity answering to the name could be found, men did not for that reason suppose that none existed, but imagined that it was something peculiarly abstruse and mysterious.
The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back. But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small.
If non-linear leaps in intelligence and ability are possible, why haven't these effects been observed in our schools? I believe the answer lies in the profound inertia of human thought: when an entire society believes something is impossible, it suppresses, by its very way of life, the evidence that would contradict that belief.
En un mot, pour tirer la loi de l'expérience, if faut généraliser; c'est une nécessité qui s'impose à l'observateur le plus circonspect.In one word, to draw the rule from experience, one must generalize; this is a necessity that imposes itself on the most circumspect observer.
Yeni bilim'in gelişmesiyle, geleneksel din biçimleri, giderek etkisini yitirmiş Avrupa'da, dinsel değerlerin yitirilmesi tehlikesi başgöstermiştir. Dostoyevski bu korkuyu şu ünlü tümcesinde dile getirmiştir: "Tanrı yoksa, her şey mümkündür.
