I was wondering about a sentence like this:
If nature were to design a bicycle, how would it look?
Is nature missing an article? Should it be "a nature" or "the nature", or is it correct as is? Could you also explain why?
Nature, in this context, means "Mother Nature", so it's more of a proper name in this case, which never requires an article.
'Nature' can also mean "a defining trait" as a general noun, such as "Human nature". In those casees, articles are possible, such as in
I can't think of an example where one would use "a nature", with an indefinite article, except in compound words such as
in which case the article refers to the "lover" part, of course.
There are several of these words that spring to mind :)
Compare for instance
All earth's children are beautiful. Earth's atmosphere protects it. We only have one earth, we should cherish it.
Or, slightly in a different direction:
God's creation is beautiful. Many a god lived on Olympus. The god of small things.
When used without an article, we refer to the entity or idea as a personification of that idea or entity. With an article we refer to it as either a specific instantiation or physical representation of the idea.
