It would seem that liberalism is not a new phenomenon. Here are two quotes from the book I’m reading currently, The Idiot by Fyodor Dostoyevsky, published in 1869, which sound like the Democratic convention:
“I can but thank you,” he said, in a tone too respectful to be sincere, “for your kindness in letting me speak, for I have often noticed that our Liberals never allow other people to have an opinion of their own, and immediately answer their opponents with abuse, if they do not have recourse to arguments of a still more unpleasant nature.”
“My Russian liberal goes so far as to reject Russia; that is, he hates and strikes his own mother. Every misfortune and mishap of the mother-country fills him with mirth, and even with ecstasy. He hates the national customs, Russian history, and everything. If he has a justification, it is that he does not know what he is doing, and believes that his hatred of Russia is the grandest and most profitable kind of liberalism.”
