Beyond Culture

His biggest claim is that culture itself is an extension of man. Extensions also exist in their own evolutionary realm, as well. That is, they evolve on their own and do not directly influence human evolution.

The 'transference' of 'extension transference' is a term he coined to describe when people regard a symbol to actually be its referent. The clearest example of this would be language; like when people do not realize that words are merely symbolic to their referents. 

For example, there is nothing inherently watery about the physical object water, at least in terms of the symbolic acoustic properties that are produced when someone utters water. Evidence for this would be the fact that across languages there are thousands of unique words that all refer to water. 

Culture, as an extension, is also a good example; extension transference of culture happens naturally when people are unaware of the extent to which culture shapes how they perceive time and space, or that culture shapes their perception of them at all. {Wikipedia]
