By splitting my post up you've managed to miss the entire point of what I was saying. You were also replying to a post from 3 months ago. My point was that we can know the rock continues to exist outside of our mind because this is the best explanation for the continuity of our perceptions.Do you believe or disbelieve it is there?
No, you continue to know it exists because you believe it to exist silly.
You continue to know it exists just because you continue to believe it exists, as perception hasn't anything to do with what you know exists silly.
