Andrzej Sapkowski said this quote
“ You've a right to believe that we're governed by Nature and the hidden Force within her. You can think that the gods, including my Melitele, are merely a personification of this power invented for simpletons so they can understand it better, accept its existence. According to you, that power is blind. But for me, Geralt, faith allows you to expect what my goddess personifies from nature: order, law, goodness. And hope. ”
