Let's consider the following inequality: people != people if we imposed different interpretations on both sides，then we certainly could conclude the first 'people' is non-equivalence to the second 'people' in semantic. Semantic of things is not reflected in the literal meaning, but is reflected in interpreter's behavior and its impact on the environment/world. my two cents. regards Peng > > What am I missing? >Received on Saturday, 3 July 2010 05:46:39 UTC
