没有比较就没有鉴别,也就没有优劣之分。做个实验可说明这个道理。把三个玻璃杯装满清水,然后向第一个杯里放入少量食盐,向第二个杯里放几滴食用油,第三个杯子保持原样。把它们放在阳光下观察就会发现:第一个杯子里的盐溶化后,看上去与装着清水的杯子似乎没有什么两样,只有品尝时才能辨别出两者的不同:一杯是咸的,一杯是淡的。而滴进油的水杯则不然,油花浮在水面上,一眼就能把它与清水区别开来。但是,当你把漂在水面上的油花拨开,剩下 There is no comparison without discrimination, there is no advantage or bad points. To be an experiment to illustrate this truth. Put the three glasses full of water, then put a small amount of salt into the first cup and a few drops of cooking oil into the second cup, leaving the third cup intact. When you look at them in the sun, you see that the salt in the first cup does not seem to be the same as a cup filled with fresh water, and the distinction between the two is only discernible: one is salty, one is cup It is light.
