Comparisons are the bedrock of all human thinking no matter where it is done on this earth in every culture. We compare things with one another and with themselves through memory to know if they are what we are looking for. We need memory and time to do that regardless of how brief and spontaneous a comparison may be. Thus thought is a dynamic process in its minutest form and needs time to be connected and unfolded to draw meaning as we compare it to other thoughts.
