Re: All I want is a smartphone with long battery life that doesn't blow up. Is that too much to ask?
Sorry, your logic fails to meet an unpassable syntax. The only assumption or confirmation of anything I can make is that I exist. I am, and my sensory inputs give an indication that something else other than me may also exist. I can parse probabilities mathmatically and logically just fine. No contradictions there.
However, if you ask me how I know "anything", that is a longer answer.
