Alexander the Great comes up to you and says "if I was not me, I wish I were you" and your response is "If I wasn't myself, I'd still wish to be myself".
Diogenes was captured by pirates while on voyage to Aegina and sold as a slave ... Being asked his trade, he replied that he knew no trade but that of governing men, and that he wished to be sold to a man who needed a master.
Alexander the Great was captured by pirates too. He forced them to increase his ransom because he was insulted that it was so small, and spent much of his time forcing them to listen to the poetry he wrote. Which is also hilarious IMO.
Zeno was killed while he was engaged in a plot to overthrow the tyrant Nearchus. This account tells that he was captured, and that he was killed after he refused to give the names of his co-conspirators.[3][8] Before his death, Zeno is said to have asked to whisper the names into Nearchus's ear, only to bite the ear when Nearchus approached, holding on until he was killed.[3]
And the time this dialogue took place during that same meeting…
In another account of the conversation, Alexander found the philosopher looking attentively at a pile of human bones. Diogenes explained, "I am searching for the bones of your father but cannot distinguish them from those of a slave."
The argument makes less sense outside of it's context. Moore was responding to the skeptical position that we're all in a simulation. Moore argues that this skeptical argument undermines itself: all of the language, terms and concepts which form the simulation argument are based on the sensory experience that the argument would effectively dismiss. Furthermore, any argument that we're in a simulation is epistemologically on a par with the argument that we're not. Therefore we should have less confidence in the skeptical argument than the common sense conclusion that we have hands.
I disagree with Moore's first point. Hands are a social construct and are not imbued with inherent reality. They gain reality only when observed by a conscious agent.
I get rather irritated with those arguments because they only return to the start. "Here, a world". "Is it how we experience it, though, and why and how; if not, what's behind?". "Bullshit, a world". That's hardly an answer. And, personally, it feels intellectually dishonest because the question was larger than just "is there a world?".
I prefer an answer like saying that doubting the world in any form might be a mistake on its own because [reasons]. I do not agree, but at least there's explanations and communication.
Also, I think they are fighting a straw man. For instance, I doubt many things about the Universe, our knowledge, our minds, etc. Yet, I accept there are phenomena which appear to me. This has been the case since the ancient school of skepticism, and I have yet to meet a person which declares themself a skeptic and does not do this to some degree. For example, I know I'm hungry right now. I don't know if the pain is real in any other deeper level, or if it is like the pain in a dream that goes away when one wakes up, or a delusion that is felt without external stimuli, or whatever. I don't know the nature of it, yet it is an experience I must attend. I can even add that the mechanisms behind, the anatomical knowledge and such is useful, but it might be entirely wrong or be as illusory as the pain itself. The straw man is that skeptics would say: "I don't know if I'm really feeling hungry", "I don't know if I want to eat" or something like that.
Why does it matter, then? Because it changes everything. In my case, it made me go from a realist teenager to an instrumentalist adult in science. From an atheist teenager to an agnostic adult.
The discussion derives in many interesting branches too. The mere "does it matter if the world is different from what we perceive if we cannot perceive it in any other way?" is an example. Many people answer yes or no without justifying it. And, at this point, some people might be wondering why we need to justify every single belief we hold and every single thing we say, like the ones throughout my comment, and that in itself is a new good question that emerges. The possibility of having any of these conversations is also a good question, and so on...
So philosophy is not going too far, in my opinion. Some philosophers might go too far, but I really think they are rare (or misunderstood).
There is a fine - but very important - line between someone who lives in a barrel jar and jerks off in the middle of the street and someone who lives in a barrel jar and jerks off in the middle of the street for philosophical reasons.
