Plato dramatically puts the detachment of the philosopher from his time this way: to philosophize is to prepare to die.
Plato worried that philosophical writing would take the place of living conversations for which, in philosophy, there is no substitute.
(As Plato:) There is nothing superstitious about forcing bad consequences for the hubris of paternalistic utopianism. Humanity should never be frozen into a vision of the best. A creative society must be willing to tolerate some degree of instability because creativity is inherently unstable.
