How Does Language Map onto the World? Yes. That is like saying phenomenal phenomenon. In terms of Kantian lingo anyway.
In science phenomenon is just something we experience and then try and understand.
Language is also a nuanced term. If we are talking about how language is learned it is fair to say spacial and temporal position matters just as much as, if not more so, than categorising similar elements/ideas/experiences.Furthermore what we experience has emotional context always - be this through needs, wants or questions.
The World is essentially our language NOT some ‘experience of’ The World. Consciousness is ‘experience of’, as in experience of some ‘thing’. Verbalising/labelling the ‘thing’ (phenomenon) is another step. A table is a table because you understand it as such not because it is a table. A table to an ant is not … maybe some creatures other tha humans grasp the purpose of a table BUT that said it is likely only a human item not a universal item as it serves a human function not a universal one.
Other items, such as trees, will likely be ‘understood’ by other animals in roughly the same manner, but by something like an ant … no way.
