Terence McKenna was a psychonaut and philosopher deeply interested in the workings of consciousness. In this video he discusses the idea that the world is made of language.

A code is a rule for converting a piece of information (for example, a letter, word, phrase, or gesture) into another – usually shortened or covert – form or representation (one sign into another sign), not necessarily of the same type.

In communications and information processing, encoding is the process by which information from a source is converted into symbols to be communicated. Decoding is the reverse process, converting these code symbols back into information understandable by a receiver.
