“Some things dwell in our minds that should never be afforded egress. You have to learn such, your mind is naïve and insipid. (Fifth Shadowlord)”

“The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then — to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn.”

“You will have to forgive me, Major Woodruffe. I am new to marriage, and perhaps more given to jealousy than some of the more experienced husbands that you know. It is possible that you seek only friendship with my wife. If, however, you entertain any other--"-Sebastian to Woodruffe"I assure you that such a thing is the furthest thing from my mind."-Woodruffe to Sebastian"Come now, Major. We are both men. Such ideas are never far from our minds at all. But if you do anything that causes me to think that your mind dwells long on that particular idea, I will thrash you, I will ruin you, and I will probably kill you.-Sebastian to Woodruffe”

“The problem with any philosophical consideration is that once you open a door in your mind, you can never close it. Once you learn something, you can never convince your mind that you didn't learn it. If you learn the world is round, you can never fit in with a world that thinks it's flat.”

“some things you will think of yourself,...some things God will put into your mind”

“Reading words puts them in your mind. You never forget. Even when you don't get a chance to dwell on the music, you can hear it in your head.”
