Edward Sapir Quote
It would be naïve to imagine that any analysis of experience is dependent on pattern expressed in language. Any concept, whether or not it forms part of the system of grammatical categories, can be conveyed in any language. If a notion is lacking in a given series, it implies a different configuration and not a lack of expressive power.
