Dumping my faves as wall of text, sorry. Some of these are attributed to the author instead of the character.
“It's like everyone tells a story about themselves inside their own head. Always. All the time. That story makes you what you are. We build ourselves out of that story.” ― Patrick Rothfuss, The Name of the Wind
“Perhaps the greatest faculty our minds possess is the ability to cope with pain. Classic thinking teaches us of the four doors of the mind, which everyone moves through according to their need.
First is the door of sleep. Sleep offers us a retreat from the world and all its pain. Sleep marks passing time, giving us distance from the things that have hurt us. When a person is wounded they will often fall unconscious. Similarly, someone who hears traumatic news will often swoon or faint. This is the mind's way of protecting itself from pain by stepping through the first door.
Second is the door of forgetting. Some wounds are too deep to heal, or too deep to heal quickly. In addition, many memories are simply painful, and there is no healing to be done. The saying 'time heals all wounds' is false. Time heals most wounds. The rest are hidden behind this door.
Third is the door of madness. There are times when the mind is dealt such a blow it hides itself in insanity. While this may not seem beneficial, it is. There are times when reality is nothing but pain, and to escape that pain the mind must leave reality behind.
Last is the door of death. The final resort. Nothing can hurt us after we are dead, or so we have been told.” ― Patrick Rothfuss, The Name of the Wind
“We understand how dangerous a mask can be. We all become what we pretend to be.” ― Patrick Rothfuss, The Name of the Wind
“Frodo: I can't do this, Sam. Sam: I know. It's all wrong. By rights we shouldn't even be here. But we are. It's like in the great stories, Mr. Frodo. The ones that really mattered. Full of darkness and danger, they were. And sometimes you didn't want to know the end. Because how could the end be happy? How could the world go back to the way it was when so much bad had happened? But in the end, it's only a passing thing, this shadow. Even darkness must pass. A new day will come. And when the sun shines it will shine out the clearer. Those were the stories that stayed with you. That meant something, even if you were too small to understand why. But I think, Mr. Frodo, I do understand. I know now. Folk in those stories had lots of chances of turning back, only they didn't. They kept going. Because they were holding on to something. Frodo: What are we holding onto, Sam? Sam: That there's some good in this world, Mr. Frodo... and it's worth fighting for.” ― J.R.R. Tolkien, The Two Towers
"We do have a lot in common. The same earth, the same air, the same sky. Maybe if we started looking at what's the same instead of always looking at what's different... well, who knows?" -Meowth
"I see now that the circumstances of one's birth are irrelevant; it is what you do with the gift of life that determines who you are." -Mewtwo
"My faith in the gods is this: they are indifferent to my suffering" -Tomlos
"There is no struggle too vast, no odds too overwhelming, for even should we fail — should we fall — we will know that we have lived." ― Anomander Rake
"I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was chasing after wind. For in much wisdom is much grief and he that increaseth knowledge increaseth sorrow." - Al Mualim
"Why do our instincts insist on violence? I have studied the interactions between different species. The innate desire to survive seems to demand the death of the other. Why can they not stand hand in hand? So many believe the world was created through the works of a divine power - but I see only the designs of a madman, bent on celebrating death, destruction, and desperation." - Altaïr Ibn-La' Ahad
"God is dead. God remains dead. And we have killed him. Yet his shadow still looms. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives: who will wipe this blood off us? What water is there for us to clean ourselves? What festivals of atonement, what sacred games shall we have to invent? Is not the greatness of this deed too great for us? Must we ourselves not become gods simply to appear worthy of it?" —Nietzsche
"You guys, having some satanic guitar pick isn't gonna make your rock any better... because Satan's not in a guitar pick, he's inside all of us. In herein your hearts. He's what makes us not want to go to work, or exercise, or tell the truth. He's what makes us want to party and have sex with each other all night long. He's that little voice in your mind that says "Fuck you" to the people you hate." - Open Mic Night Guy from "Tenacious D in The Pick of Destiny"
"'Modest relevance,' the demon said. 'I would tell you a tale, brother. Early in the clan's history, many centuries past, there arose, like a breath of gas from the deep, a new cult. Chosen as its representative god was the most remote, most distant of gods among the pantheon. A god that was, in truth, indifferent to the clans of my kind. A god that spoke naught to any mortal, that intervened never in mortal affairs. Morbid. The leaders of the cult proclaimed themselves the voice of that god. They wrote down laws, prohibitions, ascribances, propitiations, blasphemies, punishments for nonconformity, for dispute and derivations. This was but a rumor, said details maintained in vague fugue, until such time as the cult achieved domination and with domination, absolute power.' 'Terrible enforcement, terrible crimes committed in the name of the silent god. Leaders came and went, each further twisting words already twisted by mundane ambition and the zeal for unity. Entire pools were poisoned. Others drained and the slits seeded with salt. Eggs were crushed. Mothers dismembered. And our people were plunged into a paradise of fear, the laws were made manifest and spilled blood the tears of necessity. False regret with a chilling gleam in the center eye. No relief awaited and each generation suffered more than the last.' L'oric studied the demon at his side. 'What happened?' 'Seven great warriors from seven clans set out to find the Silent God, set out to see for themselves if this god had indeed blessed all that had come to pass in its name' 'And did they find the silent god?' 'Yes, and too, they found the reason for its silence. The god was dead. It had died with the first drop of blood spilled in its name.'" - Exchange between L'oric and Greyfrog
"Yes - it tells us that you participate in the mass cultural delusion that the sun's apparent position relative to arbitrarily defined constellations at the time of your birth somehow affects your personality." - Sheldon Cooper on astrology “Sometimes the prize is not worth the costs. The means by which we achieve victory are as important as the victory itself.” -Dalinar Kholin
“Just because I do not accept the teachings of the devotaries does not mean I've discarded a belief in right and wrong." "But the Almighty determines what is right!" "Must someone, some unseen thing, declare what is right for it to be right? I believe that my own morality -- which answers only to my heart -- is more sure and true than the morality of those who do right only because they fear retribution.” -Exchange between Jasnah Kholin and Shallan Davar
“Hindsight, I think, is a useless tool. We, each of us, are at a place in our lives because of innumerable circumstances, and we, each of us, have a responsibility (if we do not like where we are) to move along life's road, to find a better path if this one does not suit, or to walk happily along this one if it is indeed our life's way. Changing even the bad things that have gone before would fundamentally change who we are, and whether or not that would be a good thing, I believe, it is impossible to predict. So I take my past experiences... and try to regret nothing.” -Drizzt Do'urden
“Station is the paradox of the world of my people, the limitation of our power within the hunger for power. It is gained through treachery and invites treachery against those who gain it. Those most powerful in Menzoberranzan spend their days watching over their shoulders, defending against the daggers that would find their backs. Their deaths usually come from the front." -Drizzt Do'Urden”
“Loss of empathy might well be the most enduring and deep-cutting scar of all, the silent blade of an unseen enemy, tearing at our hearts and stealing more than our strength” - Drizzt Do'Urden
