On Truth and Lie in an Extra-Moral Sense https://web.archive.org/web/20180625190456/http://oregonstat...
One serious problem we're facing lately is that truth is not always predictive of how systems controlled by bad-faith actors will behave and evolve. We live in a post-truth era, made possible by social networking and information technologies in general. It's not enough to "lie according to a fixed convention," as there are now multiple competing conventions.
This was always the case to some extent, but these days the impedance mismatch between truth and consequences is a target for zero-sum arbitrage. The truth won't set you free if you join the wrong cult; it's more likely to bankrupt you or worse.
People question this all the time
1. simulate a world with very basic "physical" rules (so it is free from human bias)
2. let the simulation run until organisms exist
3. let it run longer so the organisms develop language
4. now see if the organisms talk about things like "consciousness" and "why are we here"
The nice thing is that we don't have to do the experiment to think about what it means if 4 happens or not.
I'm not sure I've ever met anyone I would assume has not considered the basic questions of our existence. Unless they were severely mentally disabled, or something like that.
For a more public measure I suppose you could look at religion, which seems to be a fundamental attempt at answering those questions. Most people are religious or have some kind of religious belief.
You said it yourself, you would assume they question it, meaning you are not certain. This topic is always very much tabu, and the system is built to classify automatically every One that question it as weird and not normal. Religion should be banned, as is misleading and idealogically harm people by brainwashing them. I live in Europe and was in Canada (Waterloo) for a bit. The difference of social opinion if you follow or not religion is huge, I was shocked. Growing up in Italy I can confirm that even Italy is not so brainwashed by it.
This question is the subject of so many poems, so many pieces of literature, so many movies, that you're forced to confront it multiple times in school, and you're forced by your very existence to confront it once you hit certain levels of mental development. You're forced to confront it many times in your life - perhaps first when you gain a theory of mind (before age 10), again when you first truly realize you will die, again when someone very close to you dies, when you propose/marry (if you do), when you have your first child (if you do), when you get a cancer diagnosis (if you do), when you consider taking your own life (if you do)... all of these common life events force you to confront it deeply.
Most people make peace with it in some form, and most realize that questioning it daily does not make a difference, you simply have to either accept an answer (whether that's "god", or "for no reason", or "I'm not sure yet, I need to check back in after I get older"), or decide that there is no simple answer, and they have to live with that.
I don't think this is a well defined question. Definitions aren't found in nature or the laws of science, but objects that we define and introduce into a logical context. There may be multiple, contradictory definitions of a word. That is fine, as long as you pick one, and you're clear about which one you picked.
It always has been what you believed in.
E.g. at 1 point the Earth was flat. Now it's round. 100s of years later maybe it's a Hexagon.
The so-called knowledge and backing all come back to certain assumptions holding and that's based on the knowledge today. It's not real real reality. For all we know we could be in a game simulation and there are real real humans pulling the strings.
That can´t be it. By that statement if I belive that I can fly that would not be the "Truth". Therefore the "Truth" has to be a CONSTANT.
Can you believe your own senses? A car air freshener tells your nose that theres freshly cut summer hay around, but there isn't. You watch a tv and see Sandra Bullock floating in space. That’s a lie, it was movie magic. Maybe you know that, maybe you don’t. You’re not even seeing her, you’re seeing some flashing lights which convert to electrical signals your brain interprets as being true. Can you trust those signals? People hallucinate all the time. The truth is they can hear voices, even though nobody else can, because of misfiring neurons.
You can probably have mathematical truth - at least as far as your universe appears to work. That truth can be tested and refined, but for day to day truth things are more nuanced.
1st what is to fly? You've already made assumptions i.e. beliefs elsewhere.
You can definitely fly. Try it on a cliff. You might die. You might not go very far. But you can.
The earth has always been earth-shaped. We can think it’s flat, spherical, “turnip-shaped”[1] but the universe doesn’t care what we think. The earth doesn’t change shape based on our perception.
[1] Yes some people think this for some reason I can’t fathom
And you never needed more than 640KB of RAM [1] right? Your "statement" is based on your knowledge today. You'd be burned for witchcraft back in the days for saying the earth was not flat.
> but the universe doesn’t care what we think
Assuming you know what the universe is. Your theory is based on your limited today knowledge. Someone sometime in the future could say something completely different (just like you talking about those of the past).
