As to external things, who is there who is ignorant of the uncertainty of them? In one day vast riches have often come absolutely to nothing. Numbers of persons who have been of the highest consideration, and who have enjoyed the highest honours that the earth affords, have come into disrepute from causes which they neglected or despised. The most mighty powers and authority of kings have been overthrown, and have disappeared in a very brief moment of time.

There is an example to testify to the truth of my argument in Dionysius, who lived at Corinth, who had been tyrant of Sicily, and who, after he was expelled from his dominions, took refuge in Corinth; and though he had been so mighty a sovereign, became a schoolmaster.

There is another witness to the same point in Croesus, the king of Lydia, the wealthiest of all monarchs, who, having conceived the hope of destroying the kingdom of the Persians, not only lost all his men, but was taken prisoner, and was at the point of being burnt alive.

And there are witnesses of dreams not only among men, but also among cities, and nations, and countries; Greece is such, and the region of the barbarians, and inhabitants of continents, and islanders, and Europe and Asia, and the west, and the east; for absolutely nothing whatever has ever remained in its original condition; but everything has in every particular been subject to change.

Egypt had once the supreme authority over many nations, but now it is a slave. The Macedonians at one time were so flourishing and powerful that they had obtained the supreme dominion over the whole world; but now they pay yearly tribute, which is levied on them by their masters, to the collectors of the revenue.
