What do you mean? he said.

I mean to say that there do exist natures gifted with those opposite qualities.

And where do you find them?

Many animals, I replied, furnish examples of them; our friend the dog is a very good one: you know that well-bred dogs are perfectly gentle to their familiars and acquaintances, and the reverse to strangers.

Yes, I know.

Then there is nothing impossible or out of the order of nature in our finding a guardian who has a similar combination of qualities?

Certainly not.

Would not he who is fitted to be a guardian, besides the spirited nature, need to have the qualities of a philosopher?
