“Every age has its peculiar folly; some scheme, project, or phantasy into which it plunges, spurred on either by the love of gain, the necessity of excitement, or the mere force of imitation. Failing in these, it has some madness to which it is goaded by political or religious causes, or both combined.” - Charles Mackay [Extraordinary Popular Delusions and the Madness of Crowds, “The Crusades.”]
“I can’t stand up and praise or blame anything relating to human actions and human concerns, on a simple view of the object, as it stands stripped of every relation, in all the nakedness and solitude of metaphysical abstraction. Some gentlemen count circumstances as nothing, but in fact they are what give to every political principle its distinguishing colour and discriminating effect. The circumstances are what make every civil and political scheme beneficial or harmful to mankind.” - Edmund Burke [Reflections on the Revolution in France]
