Just over a century ago, George Santayana wrote about a growing illiberal trend among those who claim to be politically liberal. To my mind this is what Brexit is all about - finding some way to reverse the trend Santayana describes so elegantly.
Liberalism had been supposed to advocate liberty; but what the advanced parties that still call themselves liberal now advocate is control, control over property, trade, wages, hours of work, meat and drink, amusements, and in a truly advanced country like France control over education and religion; and it is only on the subject of marriage (if we ignore eugenics) that liberalism is growing more and more liberal.
Those who speak most of progress measure it by quantity and not by quality; how many people read and write, or how many people there are, or what is the annual value of their trade; whereas true progress would rather lie in reading or writing fewer and better things, and being fewer and better men, and enjoying life more.
But the philanthropists are now preparing an absolute subjection of the individual, in soul and body, to the instincts of the majority—the most cruel and unprogressive of masters; and I am not sure that the liberal maxim, "the greatest happiness of the greatest number," has not lost whatever was just or generous in its intent and come to mean the greatest idleness of the largest possible population.
