Mao Zedong: “As for the so-called love of humanity, there has been no such all-inclusive love since humanity was divided into classes. All the ruling classes of the past were fond of advocating it, and so were many so-called sages and wise men, but nobody has ever really practiced it, because it is impossible in class society. There will be genuine love of humanity — after classes are eliminated all over the world. Classes have split society into many antagonistic groupings; there will be love of all humanity when classes are eliminated, but not now. We cannot love enemies, we cannot love social evils, our aim is to destroy them. This is common sense; can it be that some of our writers and artists still do not understand this?”
