"This reining-in of the imagination which I am recommending will also forbid us to summon up the memory of past misfortune, to paint a dark picture of the injustice or harm that has been done us, the losses we have sustained, the insults, slights and annoyances to which we have been exposed: for to do that is to rouse into fresh life all those hateful passions long laid asleep—the anger and resentment which disturb and pollute our nature. In an excellent parable, Proclus, the Neoplatonist, points out how in every town the mob dwells side by side with those who are rich and distinguished: so, too, in every man, be he never so noble and dignified, there is, in the depth of his nature, a mob of low and vulgar desires which constitute him an animal. It will not do to let this mob revolt or even so much as peep forth from its hiding-place; it is hideous of mien, and its rebel leaders are those flights of imagination which I have been describing."
