Slavery, you know, is nothing else than the unwilling labor of many. Therefore to get rid of slavery it is necessary that people should not wish to profit by the forced labor of others and should consider it a sin and a shame. But they go and abolish the external form of slavery and arrange so that one can no longer buy and sell slaves, and they imagine and assure themselves that slavery no longer exists, and do not see or wish to see that it does, because people still want and consider it good and right to exploit the labor of others.
You have, let us say, a promising politician, a rising artist that you wish to destroy. Dagger or bomb are archaic, clumsy and unreliable - but teach him, inoculate him with chess.
It is easy to remove the mind from harping on the lost illusion of immortality. The disciplined intellect fears nothing and craves no sugar-plum at the day's end, but is content to accept life and serve society as best it may. Personally I would not care for immortality in the least. There is nothing better than oblivion, since in oblivion there is no wish unfulfilled. We had it before we were born, yet did not complain. Shall we whine because we know it will return? It is Elysium enough for me, at any rate.
