You’ve heard about it. You’ve read about it. You’ve watched the television documentaries. The de Havilland Comet. Two mysterious crashes in the Mediterranean near Rome. 56 people dead. The planes exploded in mid-air when their pressure cabins ruptured at the corners of the square windows. A hard lesson learned about pressurized airliners, square windows, and metal fatigue. But you haven’t heard the whole story. Find out what really happened in this first video in the series Aircrash Minority Report.

QotD: Surfing the waves of resentment as a political career

Filed under: History, Politics, Quotations — Tags: , , , , — Nicholas @ 01:00

Those who, for political reasons, keep past oppression or crime constantly before the mind of the descendants of the victims (that is to say, descendants of the victim group, not necessarily of the individual victims) help to foment and foster a deep mistrust or resentment that is no longer justified, but which can lead people in effect to cut off their noses to spite their faces.

This is to the great advantage of political entrepreneurs who surf resentment as surfers ride waves in Hawaii; and such resentment, the most damaging of all emotions, can easily become a self-reinforcing loop. It is not that past oppression or crime should be forgotten, much less denied, but that past achievements and change for the better must also be recognised, lest oppression and crime come to occupy minds entirely and distort decisions.

It is the same with injustice. It is important to oppose injustice, but just as important not to see it everywhere. To ascribe everything that you think undesirable to injustice may blind you to its real causes.
