One of Plato's many profound insights when he has Socrates draw an implication from his definition of "love" (eros or desire), namely the observation that "Given our agreement that the aim of love is the permanent possession of goodness for oneself, it necessarily follows that we desire immortality along with goodness, and consequently the aim of love has to be immortality as well" (207a). He then links all human (and even animal) acts of creativity and procreativity to this desire for immortality, since they are attempts to create something that will outlive our own mortality, a second-hand immortality.
So how do these ancient insights illuminate the contemporary world? Well, if what we all ultimately desire is immortality, and the permanent possession of good things for oneself, and if money can now buy the technology to make these goals achievable, then we can expect the super-rich to spend their fortunes achieving the goal of immortality, which has, until now, seemed impossible and unattainable. It is not enough for them to possess all good things for themselves but to possess them forever. Immortality will not be for everyone but only for the elite few, who, by attaining immortality, will cease to be human.
