In this paper I consider the concept of linguistic dynamism from a materialist and evolutionary perspective. The paper begins with a description of the evolved human traits that account for the variability of response within specific contexts and the degree to which such variability is effective in safeguarding the integrity of the system while allowing for emergence and uptake of adaptive behaviour. From here, the paper draws on the architecture of Systemic Functional Linguistics and the recursive mechanisms of redundancy and articulation to outline how this evolved variability of response can account for the emergence of: (i) higher orders of extension and abstraction in the language system; and (ii) an increase in the meaning potential of the system at each level of abstraction. These two processes are seen as naturally occurring and mutually reinforcing and hence as the beginnings of a materialist account of creativity in language.

在本文中，我从唯物主义和进化论的角度考虑了语言活力的概念。本文首先描述了人类进化特征，这些特征解释了特定环境中反应的可变性，以及这种可变性在保护系统完整性的同时允许适应性行为的出现和吸收方面的有效程度。从这里开始，本文借鉴了系统功能语言学的架构以及冗余和表达的递归机制，概述了这种进化的反应可变性如何解释以下情况的出现：（i）语言系统中的扩展和抽象的更高阶；(ii) 系统在每个抽象级别的潜在意义的增加。
