And there are other possibilities, like "naturalist," but that also has problems of confusion, because Darwin would have thought naturalist -- "Naturalist" means, of course, as opposed to "supernaturalist" -- and it is used sometimes -- Darwin would have been confused by the other sense of "naturalist," which he was, of course, and I suppose there might be others who would confuse it with "nudism".
Jsou i jiné možnosti, třeba naturalista. Tam by ale taky mohlo dojít k nedorozumění, protože Darwin by naturalistu chápal -- naturalistou samozřejmě myslím opak supernaturalisty, a občas se to takto používá. Darwina by asi mátl ten druhý význam slova naturalista, což byl samozřejmě jeho případ, a myslím, že by mohli být i tací, kteří by si to pletli s nudismem.
