Theophanu

“For him that stealeth, or borroweth and returneth not, this book from its owner,
Let it change into a serpent in his hand and rend him.
Let him be struck with palsy and all his members blasted.
Let him languish in pain crying out for mercy,
Let there be no surcease to his agony till he sink in dissolution.
Let bookworms gnaw his entrails in token of the worm that dieth not.
When at last he goeth to his final punishment,
Let the flames of Hell consume him forever.
[attributed to the Monastery of San Pedro in Barcelona, Spain]”

“I meant," said Ipslore bitterly, "what is there in this world that truly makes living worthwhile?"
Death thought about it.
CATS, he said eventually. CATS ARE NICE.”

“Don't do it! Stay away from your potential. You'll mess it up, it's potential, leave it. Anyway, it's like your bank balance - you always have a lot less than you think.”
― Dylan Moran

“The only freedom which deserves the name is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it. Each is the proper guardian of his own health, whether bodily, or mental or spiritual. Mankind are greater gainers by suffering each other to live as seems good to themselves, than by compelling each to live as seems good to the rest.”
― John Stuart Mill, On Liberty
