Ahh yes this is one of my favorite quotes and one I think about a lot.

I can't help but disagree with this.

Life has been remarkably stagnant ever since I was born. The more things change, the more they stay the same. It just takes a bit of time to realize it and recognize the patterns.

Also:

Child, all the service thou hast done to Tash, I account as service done to me. . . . because we are opposites, I take to me the services which thou hast done to him. For I and he are of such different kinds that no service which is vile can be done to me, and none which is not vile can be done to him.

Therefore if any man swear by Tash and keep his oath for the oath’s sake, it is by me that he has truly sworn, though he know it not, and it is I who reward him. And if any man do a cruelty in my name, then, though he says the name Aslan, it is Tash whom he serves and by Tash his deed is accepted.

A few other good C.S. Lewis ones:

To love at all is to be vulnerable. Love anything and your heart will be wrung and possibly broken. If you want to make sure of keeping it intact you must give it to no one, not even an animal. Wrap it carefully round with hobbies and little luxuries; avoid all entanglements. Lock it up safe in the casket or coffin of your selfishness. But in that casket, safe, dark, motionless, airless, it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable. To love is to be vulnerable.

Friendship is unnecessary, like philosophy, like art.... It has no survival value; rather it is one of those things which give value to survival.

You can never get a cup of tea large enough or a book long enough to suit me.

There was a boy called Eustace Clarence Scrubb, and he almost deserved it.
