Knut Hamsun said this quote
“ God help me, how Tolstoy sweats over drying up people's sources of life, of wild and joyful life, drying them up and making the world fat with the love of God and everyman. ... But the man is old, after all, his fountains of life run dry, without a trace remaining of human affections. ... Only someone who has become slow and watertight with old age, satiated and hardened with pleasure, will go to youth and say, Renounce! ... And yet the youth renounces nothing, but sins royally for forty years. Such is the course of nature! ”
