How can you specify an order for quote marks in LaTeX?

I have a segment where the original text uses two different quote marks next to each other like "''" to show speech within a quote. I need to recreate this in LaTeX.

subsection{35}
This from Plato: `` `To the man who has true grandeur of mind, and who contemplates all time and all being, can human life appear a great matter?' `Impossible,' says the other. `Can then such a one count death a thing of dread?' `No, indeed.' ''

That is approximately what I’m trying to do. The problem is the spaces between the quotes at the start and end are not supposed to be there but without them the quote marks are in the wrong order. It is supposed to be "''" but without spaces it is "'"'. How can I make LaTeX understand which pair of characters forms a double quote and which one is the single when there are 3 quote characters in a row?

This from Plato: enquote{enquote{To the man who has true grandeur
of mind, and who contemplates all time and all being, can human life
appear a great matter?} enquote{Impossible,} says the other.
enquote{Can then such a one count death a thing of
dread?} enquote{No, indeed.}}
