“It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till. What weather they shall have is not ours to rule.”
― J.R.R. Tolkien, The Return of the King

“I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.”
― Isaac Asimov, Roving Mind

“When you light a candle, you also cast a shadow.”
― Ursula K. Le Guin

“Faithless is he that says farewell when the road darkens.”
― J.R.R. Tolkien, The Fellowship of the Ring
