If we say "10,000 grains of sand are a pile of sand", then less than 10,000 grains of sand cannot be called a pile of sand. Then it is somewhat unreasonable to distinguish 9999 grains of sand from 10001 grains of sand. This has to set a variable boundary, but what is this boundary? We don't know now. Then the value of "10,000 grains of sand are a pile of sand" originally set as knowledge will be reduced.够辣。
