First of all, sorry for bad english. I found this post from browsing google because of curiosity and suddenly stumbled upon this post. I think I might have the same question albeit with a bit difference in which i wonder if all knowledge is based on faith. I mean how can we so sure about our sense? Have you ever done empirical test to validate your senses? This become even more weird when we include subjective experience. I don’t know. Maybe it was just that I found people’s answers to these questions interesting.
