[filed under theme 9. Objects / D. Essence of Objects / 5. Essence as Kind ]

Full Idea

If anyone thinks that a man, a horse, an animal, a plant, are distinguished by real essences made by nature, he must think nature to be very liberal, making one for body, another for an animal, and another for a horse, all bestowed upon Bucephalus.

Clarification

Bucephalus was the horse of Alexander the Great

Gist of Idea

If every sort has its real essence, one horse, being many sorts, will have many essences

A Reaction

This is a powerful argument in favour of individual essences, and strongly against kind essences. Locke at his best, I would say.
