SOCRATES: Then let us next take his two brothers, Poseidon and Pluto, whether the latter is called by that or by his other name. HERMOGENES: By all means. SOCRATES: Poseidon is Posidesmos, the chain of the feet; the original inventor of the name had been stopped by the watery element in his walks, and not allowed to go on, and therefore he called the ruler of this element Poseidon; the epsilon was probably inserted as an ornament. Yet, perhaps, not so; but the name may have been originally written with a double lamda and not with a sigma, meaning that the God knew many things (Polla eidos). And perhaps also he being the shaker of the earth, has been named from shaking (seiein), and then pi and delta have been added. Pluto gives wealth (Ploutos), and his name means the giver of wealth, which comes out of the earth beneath. People in general appear to imagine that the term Hades is connected with the invisible (aeides) and so they are led by their fears to call the God Pluto instead. HERMOGENES: And what is the true derivation? SOCRATES: In spite of the mistakes which are made about the power of this deity, and the foolish fears which people have of him, such as the fear of always being with him after death, and of the soul denuded of the body going to him (compare Rep.), my belief is that all is quite consistent, and that the office and name of the God really correspond. HERMOGENES: Why, how is that? SOCRATES: I will tell you my own opinion; but first, I should like to ask you which chain does any animal feel to be the stronger? and which confines him more to the same spot,—desire or necessity? HERMOGENES: Desire, Socrates, is stronger far. SOCRATES: And do you not think that many a one would escape from Hades, if he did not bind those who depart to him by the strongest of chains? HERMOGENES: Assuredly they would. SOCRATES: And if by the greatest of chains, then by some desire, as I should certainly infer, and not by necessity? HERMOGENES: That is clear. SOCRATES: And there are many desires? HERMOGENES: Yes. SOCRATES: And therefore by the greatest desire, if the chain is to be the greatest? HERMOGENES: Yes. SOCRATES: And is any desire stronger than the thought that you will be made better by associating with another? HERMOGENES: Certainly not.
