Not so clear, because you see, that is another question. This is why we need to define things very explicitly and then accept the implications of those definitions or we’ll never get anywhere.

Now that you accepted that there is a paradox in the original question (“is there life after death?”) you reformulated it in a way the paradox is no longer present and your meaning is less ambiguous:

“Is there something not physical that continues to exists even after the physical body no longer does?”

And that is a very interesting question, but first we have to acknowledge that it is a different question and because you asked it in a non paradoxical way it opens up avenues for exploration unavailable to the original question. I would personally start simply by asking “is there something not physical, ie. a soul, “in” a being?” That is in itself is own can of worms because even if there are “souls” they might “die” when the body does so it is not as clear cut as one might initially think, but at least is a start. I’m sure there are other approaches, but at least we should all agree: it is a different question.

My point is only unparadoxical questions can have a shot at being answered. Most of the “great questions” are paradoxes; “what came before the beginning?” sounds very profound but it will never lead anywhere, as centuries pondering it have already proven.

If we take the following questions:

P: "Is there life after death?"

Q: "Is X the same as not-X?"

Then you could argue that question P (and all "metaphysical" questions) amounts to or really has the structure of something like question Q, and that it's therefore paradoxical, trivial, or uninteresting because the answer is obviously "no" ("by definition", as you point out).

I would disagree for the following reasons:

First, if you interrogate people who ask question P what they mean by it, you're likely to find out that they're not asking anything like question Q, but rather something like the following question:

R: "Can one continue to exist in some form after your physical body stops functioning?"

Now, it's true that question P and R are different on the surface, but when most people ask P what they mean by that question is R. So underneath the surface, at the meaning level, they intend to ask R. Question R is not paradoxical, trivial, or uninteresting, and it has no obvious answer that could be arrived at "by definition".

Second, I believe even trivial-seeming questions and paradoxes are frequently much deeper and more interesting than they appear. Careful study and analysis of them could yield profound insights and areas of future research. Witness all the progress in logic from studying paradoxes and other "trivial" corner cases (like the Liar's Paradox[1], Russell's Paradox[2], etc). From such study you get things like Paraconsistent logics[3] and dialetheism,[4] which can fruitfully deal with contradictions.

Third, even things that are "true by definition" can be useful and interesting. Wittgenstein argued that all logical truths are tautologies. Well, if so, they're still worthy of study and have proven to be interesting and useful.

Finally, I am not convinced that all, most, or even many "metaphysical" questions can be charitably reduced to paradoxes, nor that they are trivially answerable "by definition".

It seems to me you are more interested in the question than in the answer. You agree with me, and then spend two paragraphs justifying why you don't want to agree with me because somehow asking the wrong question still has value. It may have historical value, poetical value, emotional value, and that of course is valuable. But as to the question itself, when everyone means something else either the question is malformed or the language is useless.

And it is not so obvious what they actually mean as everyone interprets it in a different way. Some people mean still existing in this "plane", some in some other reality, some mean to be reborn, some mean to trascend, some to reincarnate, some a mix of two, or of all.

If we keep pretending the question is right when it obviously lacks meaning and all the information necessary to be able to answer it we are never gonna find out.

But again, that is what some people want, for some things to always remain a mystery, so they ask paradoxical questions.
