Many consider language as the foundational distinction between man and animal. Language is the driving force of thought and our ability to communicate with fellow human beings enables us to dream, to aspire, to excel; animals can do no such things. Animals can also communicate but only man communicates through a mechanism that is arbitrary. Language is arbitrary, in that it is the mechanism of communication which the sounds and words do not resemble what they were meant to describe. This distinctive figurative characteristic of human language coupled with the commonly held belief that language separates man from beast are sufficient reasons for us to explore the origin of languages and how language represents reality to us and whether or not it transforms reality for us. .
Language deflects, selects, and reflects reality to us through figurative language and proper language. Does either figurative or proper language more accurately represent reality? Did they both arise at the same time or does one have to precede the other? Figurative language arose first. Rousseau, in his Essay on the Origin of Languages, deals with the problem of figurative language and proper language. He claims "that the first language had to be figurative"(pg 12) and the explanation he cites as support for his claim is his previous claim that language emerged out of passions. Rousseau argues that because language grew out of passion, the first words uttered must have been triggered by a passion. He writes "as man's first motives for speaking were of the passions, his first expressions were tropes."(pg 12).
Passion and feeling, for Rousseau, preceded reason and thought. "One does not begin by reasoning, but by feeling."(pg 11) Proper language belongs to reasoning and figurative language belongs to feeling. The first expressions used by humans came from passion, from feeling, exclusive of any reasoning and thus language must be figurative before it is proper.
