I was a good bartender. I wouldn't say I was the best bartender in New York, but I could hold my own.
There's not a single shred of evidence for the multiverse. If, in order to explain this universe, you need a theory that invents an infinite number of parallel universes - that's not a very good theory.
Theory is worth but little, unless it can explain its own phenomena, and it must effect this without contradicting itself; therefore, the facts are sometimes assimilated to the theory, rather than the theory to the facts.
I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.
We have no acceptable theory of evolution at the present time. There is none; and I cannot accept the theory that I teach to my students each year. Let me explain. I teach the synthetic theory known as the neo-Darwinian one, for one reason only; not because it's good, we know that it is bad, but because there isn't any other. Whilst waiting to find something better you are taught something which is known to be inexact.
If the weather is sunny, it is good; if the weather is rainy, it is good; if it is foggy, it is good; if it is stormy, it is good; if it is damn cold, it is good; if it is damn hot, it is good! With a positive attitude of mind, all becomes good!
...You have to pass an exam, and the jobs that you get are either to shine shoes, or to herd cows, or to tend pigs. Thank God, I don't want any of that! Damn it! And besides that they smack you for a reward; they call you an animal and it's not true, a little kid, etc.. Oh! Damn Damn Damn Damn Damn!
Whichever theory we adopt to give a rational explanation of human existence, that theory must take into account and explain the mental nature we see at work in all modern communities.
A good writer is not, per se, a good book critic. No more so than a good drunk is automatically a good bartender.
If the theory accurately predicts what they [scientists] see, it confirms that it's a good theory. If they see something that the theory didn't lead them to believe, that's what Thomas Kuhn calls an anomaly. The anomaly requires a revised theory - and you just keep going through the cycle, making a better theory.
In order to displace a prevailing theory or paradigm in science, it is not enough to merely point out what it cannot explain; you have to offer a new theory that explains more data, and do so in a testable way.
What would it mean if there were a theory that explained everything? And just what does "everything" actually mean, anyway? Would this new theory in physics explain, say the meaning of human poetry? Or how economics work? Or the stages of psychosexual development? Can this new physics explain the currents of ecosystems, or the dynamics of history, or why human wars are so terribly common?
I'll write whatever I damn please, whenever I damn please and as I damn please and it'll be good if the authentic spirit of change is on it.
I feel lucky. I do love it, mostly. At college I had it in my heart that I wanted to be a writer but I didn't want to tell anyone about it. Then I graduated and became a bartender in Philadelphia, writing during the day. I was the worst bartender in the world.
Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
If you have to signal a bartender to get a drink, then they're not looking at you, which is their problem. They're not doing their job. So don't feel rude when you signal a bartender. They're the ones who caused you to signal them. Go for it.
