Ἐγὼ διδαχθεὶς ἐν κακοῖς ἐπίσταμαι πολλοὺς καθαρμούς, καὶ λέγειν ὅπου δίκη σιγᾶν θ᾽ ὁμοίως. - Aeschylus

És fàcil, per al qui es troba lliure de penes, donar consell i fer avertiments als qui pateixen.

Ah state of mortal man! in time of weal,
A line, a shadow! and if ill fate fall,
One wet sponge-sweep wipes all our trace away.

Marvels, the Earth breeds many marvels,
terrible marvels overwhelm us.
The heaving arms of the sea embrace and swarm
with savage life. And high in the no man's land of night
torches hang like swords.
