“Everything that seems strange about quantum mechanics comes down to measurement. If we take a look, the quantum system behaves one way. If we don’t, the system does something else. What’s more, different ways of looking can elicit apparently mutually contradictory answers. If we look at a system one way, we see this; but if we look at the same system another way, we see not merely that but not this. The object went through one slit; no, it went through both. How can that be? How can ‘the way nature behaves’ depend on how – or if – we choose to observe it?”

“If, years later, I do use the slit detector to observe which way the electron went, it will mean that many years earlier the electron must have passed through one slit or the other. But if I don't use the "slit detector," then the electron must have passed through both slits. This is, of course, extremely weird. My actions at the beginning of the twenty-first century can change what happened thousands of years ago when the electron began its journey. It seems that just as there are multiple futures, there are also multiple pasts, and my acts of observation in the present can decide what happened in the past. As much as it challenges any hope of ever really knowing the future, quantum physics asks whether I can ever really know the past. It seems that the past is also in a superposition of possibilities that crystallize only once they are observed.”

“So long as we don’t try to figure out which slit [electrons] go through, they will behave as if they go through both at once. But if we try to pin down which slit they pass through, they only go through one. The mere act of making the measurement – even if we can be pretty sure that the measurement shouldn’t obstruct or influence the electron’s path – appears to turn a wave into a particle. Yes, appears to. Does the electron really pass through both slits at once when we’re not looking at its path? Does it change from wave to particle when we do look? These are, according to Bohr’s view of quantum mechanics, illegitimate questions, precisely because they are insisting on some microscopic description underlying the measurements we make. Bohr argued that there is nothing in quantum mechanics that permits us to formulate such a description. That is not what the Schrödinger equation is about. It just predicts the outcomes of measurements.”

“Each religion makes scores of purportedly factual assertions about everything from the creation of the universe to the afterlife. But on what grounds can believers presume to know that these assertions are true? The reasons they give are various, but the ultimate justification for most religious people’s beliefs is a simple one: we believe what we believe because our holy scriptures say so. But how, then, do we know that our holy scriptures are factually accurate? Because the scriptures themselves say so. Theologians specialize in weaving elaborate webs of verbiage to avoid saying anything quite so bluntly, but this gem of circular reasoning really is the epistemological bottom line on which all 'faith' is grounded. In the words of Pope John Paul II: 'By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals.' It goes without saying that this begs the question of whether the texts at issue really were authored or inspired by God, and on what grounds one knows this. 'Faith' is not in fact a rejection of reason, but simply a lazy acceptance of bad reasons. 'Faith' is the pseudo-justification that some people trot out when they want to make claims without the necessary evidence. But of course we never apply these lax standards of evidence to the claims made in the other fellow’s holy scriptures: when it comes to religions other than one’s own, religious people are as rational as everyone else. Only our own religion, whatever it may be, seems to merit some special dispensation from the general standards of evidence. And here, it seems to me, is the crux of the conflict between religion and science. Not the religious rejection of specific scientific theories (be it heliocentrism in the 17th century or evolutionary biology today); over time most religions do find some way to make peace with well-established science. Rather, the scientific worldview and the religious worldview come into conflict over a far more fundamental question: namely, what constitutes evidence. Science relies on publicly reproducible sense experience (that is, experiments and observations) combined with rational reflection on those empirical observations. Religious people acknowledge the validity of that method, but then claim to be in the possession of additional methods for obtaining reliable knowledge of factual matters — methods that go beyond the mere assessment of empirical evidence — such as intuition, revelation, or the reliance on sacred texts. But the trouble is this: What good reason do we have to believe that such methods work, in the sense of steering us systematically (even if not invariably) towards true beliefs rather than towards false ones? At least in the domains where we have been able to test these methods — astronomy, geology and history, for instance — they have not proven terribly reliable. Why should we expect them to work any better when we apply them to problems that are even more difficult, such as the fundamental nature of the universe? Last but not least, these non-empirical methods suffer from an insuperable logical problem: What should we do when different people’s intuitions or revelations conflict? How can we know which of the many purportedly sacred texts — whose assertions frequently contradict one another — are in fact sacred?”

“For if we are observed in all matters, we are constantly under threat of correction, judgment, criticism, even plagiarism of our own uniqueness. We become children, fettered under watchful eyes, constantly fearful that — either now or in the uncertain future — patterns we leave behind will be brought back to implicate us, by whatever authority has now become focused upon our once-private and innocent acts. We lose our individuality, because everything we do is observable and recordable." [The Eternal Value of Privacy, May 18, 2006]”

“It necessarily follows that chance alone is at the source of every innovation, and of all creation in the biosphere. Pure chance, absolutely free but blind, at the very root of the stupendous edifice of evolution: this central concept of modern biology is no longer one among many other possible or even conceivable hypotheses. It is today the sole conceivable hypothesis, the only one that squares with observed and tested fact. And nothing warrants the supposition - or the hope - that on this score our position is ever likely to be revised. There is no scientific concept, in any of the sciences, more destructive of anthropocentrism than this one.”

“The bus is late. Cars drive by. Rich people n cars never look at people on the street, at all. Poor ones always do ... in fact it sometimes seems they're just driving around, looking at people on the street. I've done that. Poor people wait a lot. Welfare, unemployment lines, laundromats, phone booths, emergency rooms, jails, etc.”

“Men often talked about a woman's intuition. Ostensibly it sounded complimentary and yet its intention was usually patronising and dismissive: a term for irrational flights of fancy that these silly creatures would occasionally dream up from nowhere. Sarah understood the true nature of what they were describing. It was not irrational, and nor was it a mystical sixth sense resultant of a unique feminine sensitivity. It was a simple, practical consequence of observation. When you put them in a room, women paid attention to the subtle signs people were sending, while the men concerned themselves only with the impression they were making.”

“What I like about experience is that it is such an honest thing. You may number of wrong turnings; but keep your eyes open and you will not be allowed to go very far before the warning signs appear. You may have deceived yourself, but experience is not trying to deceive you. The universe rings true wherever you fairly test it.”

“It has always been a mystery to me how Adam, Eve, and the serpent were taught the same language. Where did they get it? We know now, that it requires a great number of years to form a language; that it is of exceedingly slow growth. We also know that by language, man conveys to his fellows the impressions made upon him by what he sees, hears, smells and touches. We know that the language of the savage consists of a few sounds, capable of expressing only a few ideas or states of the mind, such as love, desire, fear, hatred, aversion and contempt. Many centuries are required to produce a language capable of expressing complex ideas. It does not seem to me that ideas can be manufactured by a deity and put in the brain of man. These ideas must be the result of observation and experience.”

“Keep moving like a man late for destiny's call. You are surrounded by people terrified of nothing at all. Terrified of silence, so they fill up the space, with real estate, keto diets, and the weather in this place. With a new season of a show you haven't watched yet. You don't need to listen. You just need to sweat at their frequency. Nod every six seconds on the dot. Laugh when the group laughs, whether it's funny or not.”
