《公孙龙子·名实论》
以彼名称呼彼物而无彼物与之相应，则彼名不适用于彼物；以此名称呼此物而无此物以之相应，则此名不适用于此物。
谓彼而彼不唯乎彼，则彼谓不行；谓此而此不唯乎此，则此谓不行。
Calling something by that name without anything to correspond to it, then that name does not apply to that thing; calling this thing by this name without anything to correspond to it, then this name does not apply to this thing.
