DEFINING REALITY

摘要

What DO we actually mean by reality? A straightforward answer is that it means everything that appears to our five senses -everything that we can see, smell, touch and , so forth. Yet this answer ignores such problematic entities as electrons, the recession and the number 5, which we cannot sense but which are very real. It also ignores phantom limbs and illusory smells. Both can appear vividly real, but we would like to say that these are not part of reality.
