“Levin had often noticed in arguments between even the most intelligent people that after enormous efforts, an enormous number of logical subtleties and words, the arguers would finally come to the awareness that what they had spent so long struggling to prove to each other had been known to them long, long before, from the beginning of the argument, but that they loved different things and therefore did not want to name what they loved, so as not to be challenged. He had often felt that sometimes during an argument you would understand what your opponent loves, and suddenly come to love the same thing yourself, and agree all at once, and then all reasonings would fall away as superfluous; and sometimes it was the other way round: you would finally say what you yourself love, for the sake of which you are inventing your reasonings, and if you happened to say it well and sincerely, the opponent would suddenly agree and stop arguing. That was the very thing he wanted to say.”
― Leo Tolstoy, Anna Karenina
