Fyodor Dostoevsky,
The Brothers Karamazov — Part IV, Book X, Chapter 6
(1880)

"It's possible for one who doesn't believe in God to love mankind, don't you think so? Voltaire didn't believe in God and loved mankind?" ("I am at it again," he thought to himself.) "Voltaire believed in God, though not very much, I think, and I don't think he loved mankind very much either," said Alyosha quietly, gently, and quite naturally, as though he were talking to someone of his own age, or even older. ”
