Re: Can you really prove your existence?
Can you really prove that you exist ? I'd really like some ideas of how you could prove your own existence absolutely without any room for refutations made against your existence.
Such a proof can only be made through deduction. Descartes tried to prove his own existence deductively: he arrived at his famous cogito, ergo sum
, but he arrived at it only through a combination of deduction and induction. No proof of one's own existence so far has been able to dispense entirely with induction, so every proof is, as Hume pointed out, not provable.
Do I exist because I am typing this post right now? How would I know that? Through my senses. Are my senses infallible? Well, I can't say that, although they have been pretty reliable in the past. But past reliability is no guarantee of future reliability. Just because the sun rose in the east this morning is no guarantee that it will do so tomorrow.
I am, nevertheless, confident that I do exist, and all the usual indicia of truth that I normally rely upon confirm that conclusion. Can I convince you
that I exist? That depends on what kinds of proof you would be willing to accept.
