 …every rational being, exists as an end in himself and not merely as a means to be arbitrarily used by this or that will…Beings whose existence depends not on our will but on nature have, nevertheless, if they are not rational beings, only a relative value as means and are therefore called things. On the other hand, rational beings are called persons inasmuch as their nature already marks them out as ends in themselves. (Kant [1785] 1998: [Ak 4: 428])
