Our language is constantly evolving and mutating but we seem to be getting further away from understanding the linguistic sources.
Our ancestors had a much deeper understanding of the meaning and significance of words, often intentionally using them as allergorical references, fully expecting each other to be able to identify the reference or sub-text and using language almost playfully.
As a race we may be more scientifically advanced but on an individual level we seemed terribly dumbed-down by comparison.

Great topic josepp.
