“I am for "peace, retrenchment, and reform" — the watchword of the great Liberal party 30 years ago. Whosoever may abandon the cause I shall never pronounce another Shibboleth, but as long as the old flag floats in the air I shall be found a steadfast soldier in the foremost ranks”

St. 5.
The Age of Bronze (1823)
Context: While Franklin's quiet memory climbs to heaven,
Calming the lightning which he thence hath riven,
Or drawing from the no less kindled earth
Freedom and peace to that which boasts his birth;
While Washington's a watchword, such as ne'er
Shall sink while there's an echo left to air.

Context: A politics of fear and resentment and retrenchment began to appear, and that kind of politics is now on the move. It’s on the move at a pace that would have seemed unimaginable just a few years ago. I am not being alarmist, I am simply stating the facts. Look around. Strongman politics are ascendant suddenly, whereby elections and some pretense of democracy are maintained – the form of it – but those in power seek to undermine every institution or norm that gives democracy meaning. In the West, you’ve got far-right parties that oftentimes are based not just on platforms of protectionism and closed borders, but also on barely hidden racial nationalism. Many developing countries now are looking at China’s model of authoritarian control combined with mercantilist capitalism as preferable to the messiness of democracy. Who needs free speech as long as the economy is going good? The free press is under attack. Censorship and state control of media is on the rise. Social media – once seen as a mechanism to promote knowledge and understanding and solidarity – has proved to be just as effective promoting hatred and paranoia and propaganda and conspiracy theories.
