The nature of language is the nature of human thought and human action, for language is no more nor less than the tool of both of these aspects of human nature.

They【M1】______ are the channels, the medium for the expression or communication of【M2】______ that which lay outside of themselves. Plato has made clear to us how【M3】______ easy it is to deceive ourselves with words, to labor under an impression that just because we can utter a sound we also necessarily know that we are talking about Words may be empty vessels and pour out【M4】______ no more than hollow sounds. We find it simple to define some words and extremely difficult to define others words. The reason is that the【M5】______ definition of a word is the experience of records. Hence the definiteness【M6】______ of a definition of a word is in proportion at the vividness of the【M7】______ experience, its meaning. We readily define chair because of our frequent experience with the object which the sound is a symbol.【M8】______ We define it in terms of our experience like an object to sit ia But a【M9】______ definition of terms like 'truth', or 'virtue', or 'honesty', or 'beauty' is a most severe trial because of the haziness or complete lack for【M10】______ experiences of this nature.
