Halliday & Matthiessen (1999: 423):
Writing from a different orientation within cognitive semantics, Lakoff (e.g. 1988) is also very critical of what he calls "objectivist metaphysics" (metaphysical realism). He presents a detailed critique of this position, also noting the problem that arises if meanings are located in the world:
To view meaning as residing only in the relationship between symbols and external reality is to make the implicit claim that neither colour categories, nor any other secondary category, should exist as meaningful cognitive categories. Yet colour categories are real categories of the mind. They are meaningful, they are used in reason, and their meaning must be accounted for. But the mechanism of objectivist cognition cannot be changed to accommodate them without giving up on the symbolic category of meaning. But to do that is to abandon the heart of the objectivist program, (p. 132)
