 Stephen Mallinder
The kind of group mentality that we had lived under since the Second World War is starting to erupt, and the craving for individualism is now much stronger. It's not as taboo anymore, as it was when I was younger.

Quotes from the same author

Augustus gradually increased his powers, taking over those of the senate, the executives and the laws. The aristocracy received wealth and position in proportion to their willingness to accept slavery. The state had been transformed, and the old Roman character gone for ever. Equality among citizens was completely abandoned. All now waited on the imperial command.
 Tacitus
No one would have doubted his ability to reign had he never been emperor.
 Tacitus

For in former times, it was not by land but on shipboard that those who sought to emigrate would arrive; and the boundless and, so to speak, hostile ocean beyond us,is seldom entered by a sail from our world.
 Tacitus
Greater things are believed of those who are absent.
 Tacitus
Conspicuous by his absence.
