i see. however, your use of the word "memory" implies something from the past. my reference to "a point on a circle" was meant to imply that the present can never be fully realized because it can only exist in the past. the neurons in the brain don't transmit information at light speed, or infinite speed. there is a delay. so any perception as the result of any stimulus to the senses is already in the past. why question the validity of memory and assume perception through the senses to be true?

sorry for any spelling or grammatical errors, i am really high right now. as if that means anything.
