It's me, I'm the postmodern audience member in Los Angeles or New York who marveled at the opera's innovative multipositionality and hybridity, in which revolutionary ideologies, exotic nativist music and dances of the Li ethnic minority on Hainan Island, and high European styles and modalities coalesced in a neo-Wagnerian Gesamtkunstwerk.

Why are the laws of logic what they are, as opposed to something else?

This is a bit like asking "why are the laws of physics what they are?", but seemingly even less tractable.

A sufficient answer is not "the laws of logic were made up by man; ask him why he made them up that way!" or something of its ilk. It's true that all explicit systems of logic were devised by people, and that through history people have devised many different such systems in order to reason about the world. But it's likewise true that some conceivable systems of logical inference work better than others to that end. The inference rules of syllogistic logic, classical propositional logic, fuzzy logic, whatever, they all to one degree or another succeed at allowing one to derive new knowledge from old knowledge, new truths from known truths, etc. Some conceivable rules of inference, such as "from two statements, infer the first one" or "from A ∨ B infer ¬B" simply don't work for transforming old knowledge into new knowledge. They are unsuccessful methods of inference. And this would seem to say something about the underlying structure of the world, that some conceivable rules of inference work and others don't. We can, if we strain very hard perhaps, imagine that it was otherwise—we can imagine a world in which "from two statements, infer the first one" does work, although we can hardly say anything about what it would be like.

So, there's my question. Why does logic work the way it does, instead of some other way? Why is the world such that these rules of inference work and those rules of inference don't work?

I have no hope of ever getting an answer to this but I'm very curious.

This doesn't say much, and it probably is tauntological in some way, but what ultimately evaluate what works is natural selection.

You’ll never get me to buy ad-free tumblr you staff-plant ass m

The dumb thing about this accusation is, I think I’m actually a lot more strident about asking people to pay for Tumblr than the Tumblr staff are. They seem pretty chill about it based on the posts I’ve seen. Which makes sense: if Tumblr goes under, what do they care, they’ll just get another job. But I’d lose a community that I really enjoy and which I’ve sunk quite a bit of time and effort into.

Look, it’s your money and you can do whatever you want with it. But I am honestly kind of baffled by people’s absolute refusal to pay for websites that they use, even though on a dollars-per-hour basis, it’s the biggest no-brainer purchase there is. Ad-free tumblr is $40/year. That’s like… two and a half movie tickets for something a lot of people are using for multiple hours per day. And the staff isn’t lying to you about the costs: after payroll taxes and health insurance and whatnot, the all-up cost of one junior software engineer is about $250,000/year. Bandwidth for serving images and video is also expensive as fuck. It does in fact take quite a bit of money to keep something like this running, even without making a single dime of profit.

if a company was never going to pay dividends or do stock buybacks, the stock would presumably be worthless. It's hard to be sure because of nft's and bitcoin but presumably. This stock that you buy to sell it later, you're either selling a promise of a future share of profits, or... idk, the thing youre imagining doesnt really exist i think, or it's bitcoin can you name a specific stock that you think works like this?

oh! yes. great question. thank you for forcing me to specifics. TSLA! (circa 2021)

this valuation has to be what, 90+% speculation? theres no way anyone thinks that TESLA will be more profitable, produce more buybacks than the rest of the car industry combined. i think a huge portion of the stock market is like this. i reblogged a thing about this recently but i cant find it, the change in the stock market over the last 10 years is almost entirely the top 10 companies

Why can’t it produce more buyback/dividends (economically equivalent except for tax purposes, which is why shareholders generally prefer buybacks) than the rest of the car industry combined in let’s say the next 10 years? TSLA does not need to be restricted to just the car industry, it could potentially expand the car industry as well, which is also not mutually exclusive with the fact it can also potentially make cars so cheaply and good that rest of the industry makes virtually no money.

I do think TSLA is probably in some sense overvalued, but the future is by definition uncertain. There are also people who value TSLA shares as gambling chips like GME. Arguably you can say this is the same case with gold or money, which have limited use except they are scarce and are widely considered to be scarce and a store of value.
