>Aren’t “concepts” encoded in how language is used, at least to some degree?

Good point and I think this shows up to the extent different languages might affect how we express particular concepts.

However I think it is more accurate to say that language solidifies and gives form to how we express concepts and the “concepts” themselves are independent of languages. Only our “expression” of these “concepts” depends on language.

For anyone interested in art and art history, this distinction was the central focus of the French surrealist painter Rene Magritte.
