Maxim Gorky said this quote

This is the way it ought to be! said the Little Russian, returning. Because, mark you, mother dear, a new heart is coming into existence, a new heart is growing up in life. All hearts are smitten in the conflict of interests, all are consumed with a blind greed, eaten up with envy, stricken, wounded, and dripping with filth, falsehood, and cowardice. All people are sick; they are afraid to live; they wander about as in a mist. Everyone feels only his own toothache. But lo, and behold! Here is a Man coming and illuminating life with the light of reason, and he shouts: 'Oh, ho! you straying roaches! It's time, high time, for you to understand that all your interests are one, that everyone has the need to live, everyone has the desire to grow!' The Man who shouts this is alone, and therefore he cries aloud; he needs comrades, he feels dreary in his loneliness, dreary and cold. And at his call the stanch hearts unite into one great, strong heart, deep and sensitive as a silver bell not yet cast. And hark! This bell rings forth the message: 'Men of all countries, unite into one family! Love is the mother of life, not hate!' My brothers! I hear this message sounding through the world!
