5. What things have proper names, and why.
Besides persons, countries also, cities, rivers, mountains, and other
the like distinctions of place have usually found peculiar names, and that for the same reason; they being such as
men have often an occasion to mark particularly, and, as it were, set before others in their discourses with them.
And I doubt not but, if we had reason to mention particular horses as often as we have to mention particular men,
we should have proper names for the one, as familiar as for the other, and Bucephalus would be a word as much
in use as Alexander. And therefore we see that, amongst jockeys, horses have their proper names to be known and
distinguished by, as commonly as their servants: because, amongst them, there is often occasion to mention this or
that particular horse when he is out of sight.
