# Symbiosism

Symbiosism is a philosophy about the mind and man's place in nature. It is a Darwinian theory, which considers language an organism residing in the human brain and claims that language is a memetic life form. Symbiosism is defined by the Leiden school.

## Overview

Memes are meanings, i.e. iso-functional neuroanatomical constructs corresponding to signs in the sense of Ferdinand de Saussure. Meanings thrive, replicate incessantly and constitute the essence of language. An essential characteristic of memes is that linguistic meanings have the nature of nonconstructible sets in the mathematical sense and do not abide by constraints governing Aristotelian logic, such as the principle of the excluded middle. The Leiden conception of the meme contrasts with the Oxford definition as a unit of imitation, a behavioral notion that in Leiden is captured by the term meme. The fecundity of memes as replicators and their fidelity of replication are limited, more so in pre-linguistic contexts.
Language is a mutualist symbiont and enters into a mutually beneficial relationship with its hominid host. Humans propagate language, whilst language furnishes the conceptual universe that guides and shapes the thinking of the hominid host. Language enhances the Darwinian fitness of the human species. Yet individual grammatical and lexical meanings and configurations of memes mediated by language may be either beneficial or deleterious to the biological host. The symbiosis is rendered more complex than just simple mutualism, both by the physiological discrepancy between language as an overall condition and the nature of individual ideas conveyed through language, as well as by the ecological difference between vertically and horizontally transmitted memes. The symbiotic theory of language propounded by George van Driem grew out of the Leiden school of language evolution, fathered by Frederik Kortlandt.
