The evidence each of us has of our own existence is inde-feasible: it is obviously impossible both to be aware of yourself (or anything else) and not to exist.
This is interesting! It is also related with the computer simulation idea. Does it mean that "as long as something I consider as 'myself,' even it is just a simulation or something else, exists, I can be aware of myself, and I exist?"
In the dialogue called the Theaetetus, Socrates discusses the question “What is knowledge?”
This whole thing reminds me of something we've talked on my art history class. The Enlightenment theme of "Triumph of Light over Darkness" was something that marks the beginning of human's attempt to actively test and explore, and this desire of knowledge has changed human's perspective on the process of getting new knowledge. It is quite obvious and interesting that back in Plato's time, what they were discussing as "knowledge" was the things that were staying there superficially waiting for people to see (or for people to realize in a coincidence) rather than the things we need to discover using calculation or analyzation. This comment is not that philosophical but I think it is somehow related to our point of interdisciplinary study.
