The Enlightenment Needs Vigorous Defense
The ideals of the Enlightenment are products of human reason, but they always struggle with other strands of human nature: loyalty to tribe, deference to authority, magical thinking, the blaming of misfortune on evildoers. The second decade of the 21st century has seen the rise of political movements that depict their countries as being pulled into a hellish dystopia by malign factions that can be resisted only by a strong leader who wrenches the country backward to make it “great again.”...Elridge Cleaver on Prison's Effect of Sense of Self
You may find this difficult to understand but it is very easy for one in prison to lose his sense of self. And if he has been undergoing all kinds of extreme, involved, and unregulated changes, then he ends up not knowing who he is. Take the point of being attractive to women. You can easily see how a man can lose his arrogance or certainty on that point while in prison! When he's in the free world, he gets constant feedback on how he looks from the number of female heads he turns when he...Elridge Cleaver talks about how prison has a detrimental effect on one's self esteem
Aristotle as the First Scientist
Aristotle repeatedly pointed out that his predecessors' work and conclusions were often marred by insufficient observation. He himself, after a remarkable analysis of the reproduction of bees, states that he cannot arrive at certain conclusions because "the facts have not yet been sufficiently ascertained. And if at any future time they are ascertained, then credence must be given to the direct evidence rather than to the theories; and to the theories also, provided that the results which the...Classification of animals, empirical observations... he got much wrong, but to call into question his achievements for this is like criticizing the invention of Calculus because Newton believed in magic.
Possibilianism
Eagleman was brought up as a secular Jew and became an atheist in his teens. Lately, though, he’d taken to calling himself a Possibilian—a denomination of his own invention. Science had taught him to be skeptical of cosmic certainties, he told me. From the unfathomed complexity of brain tissue—“essentially an alien computational material”—to the mystery of dark matter, we know too little about our own minds and the universe around us to insist on strict atheism, he said. “And we...Another flavor of secular humanism.
The Mathematical Image
The proof is elegant and the result profound. Still, it is typical mathematics; so, it’s a good example to reflect upon. In doing so, we will begin to see the elements of the mathematical image, the standard conception of what mathematics is. Let’s begin a list of some commonly accepted aspects. By ‘commonly accepted’ I mean that they would be accepted by most working mathematicians, by most educated people, and probably by most philosophers of mathematics, as well. In listing them as...How mathematics provides certainty, objectivity,
Molyneux's problem
I shall here insert a problem of that very ingenious and studious promoter of real knowledge, the learned and worthy Mr. Molyneux, which he was pleased to send me in a letter some months since; and it is this:- "Suppose a man born blind, and now adult, and taught by his touch to distinguish between a cube and a sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and the other, which is the cube, which the sphere. Suppose then the cube and sphere placed on...A blind person, familiar with a cube and sphere by touch, is made to see. Without touching the objects, would they be able to distinguish them by sight?
Greeks and Romans Lacked the Virtue of Doubt
The Greek and Roman antiquarians, and even their literati and philosophers, are chargeable with a total neglect of that spirit of doubt which subjects to a rigorous investigation both sacts, and the proofs that establish them. In reading their accounts of the history of events or of manners, of the productions and phenomena of nature, or of the works and processes of the arts, we are astonished at the composure with which they relate the most palpable absurdities, and the most fulsome and dis......and as a result, their writing reveals an incredible gullibility.
1 = 0.999999999…
This simple equation, which states that the quantity 0.999, followed by an infinite string of nines, is equivalent to one, is the favorite of mathematician Steven Strogatz of Cornell University. "I love how simple it is — everyone understands what it says — yet how provocative it is," Strogatz said. "Many people don't believe it could be true. It's also beautifully balanced. The left side represents the beginning of mathematics; the right side represents the mysteries of infinity."An equation that is challenging, provocative, and portrays both the certainty of mathematics and its infinity.
Definition of a Naturalist
If people ask me about my worldview, I say that I am a naturalist. When most people hear that word, they think of someone who spends a lot of time outdoors watching birds and admiring landscapes—and I suppose that description applies to me. But I think of naturalism as a philosophy rather than a lifestyle. F a philosophical perspective, naturalists believe that the physical universe is the universe. In other words, there are no supernatural entities or forces acting on nature, because there...It is a philosophical state of mind, grounded in empiricism, in addition to being one who appreciates nature.
Knowledge Makes Death More Painful
All our knowledge merely helps us to die a more painful death than the animals that know nothing. A day will come when science will turn upon its error and no longer hesitate to shorten our woes. A day will come when it will dare and act with certainty; when life, grown wiser, will depart silently at its hour, knowing that it has reached its term.A bleak commentary, suggesting science will prompt us to commit suicide.
