The Supporters of Trump: A Great Mystery?

I am re-reading the Richard Pevear and Larissa Volkhonsky translation of Fyodor Dostoeyevsky’s Notes from the Underground. Suddenly, I saw the following passage, which predicted the emergence of Trump and his supporters:

Man really is stupid, phenomenally stupid. That is, he’s by no means stupid, but he’s so ungrateful that it would be hard to find the likes of him. I, for example, would not be the least bit surprised if suddenly, out of the blue, amid the universal future reasonableness, some gentleman of ignoble, or, better, of retrograde and jeering physiognomy, should emerge, set his arms akimbo, and say to us all: “Well, gentlemen, why don’t we reduce all this reasonableness to dust with one good kick, for the sole purpose of sending all these logarithms to the devil and living once more according to our own stupid will!” That would still be nothing, but what is offensive is that he’d be sure to find followers: that’s how man is arranged. And all this for the emptiest of reasons, which would seem not even worth mentioning: namely, that man, whoever he might be, has always and everywhere liked to act as he wants, and not at all as reason and profit dictate; and one sometimes even positively must (this is my [i.e. Dostoyevsky’s] idea now).
