" [W]e can calculate our way into regions of miraculous improbability far greater than we can imagine as plausible. Let's look at this matter of what we think is plausible. What we can imagine as plausible is a narrow band in the middle of a much broader spectrum of what is actually possible. Sometimes it is narrower than what is actually there. There is a good analogy with light. Our eyes are built to cope with a narrow band of electromagnetic frequencies (the ones we call light), somewhere in the middle of the spectrum from long radio waves at one end to short X-rays at the other. We can't see the rays outside the narrow light band, but we can do calculations about them, and we can build instruments to detect them. In the same way, we know that the scales of size and time extend in both directions far outside the realm of what we can visualize. Our minds can't cope with the large distances that astronomy deals in or with the small distances that atomic physics deals in, but we can represent those distances in mathematical symbols. Our minds can't imagine a time span as short as a picosecond, but we can do calculations about picoseconds, and we can build computers that can complete calculations within picoseconds. Our minds can't imagine a timespan as long as a million years, let alone the thousands of millions of years that geologists routinely compute. Just as our eyes can see only that narrow band of electromagnetic frequencies that natural selection equipped our ancestors to see, so our brains are built to cope with narrow bands of sizes and times. Presumably there was no need for our ancestors to cope with sizes and times outside the narrow range of everyday practicality, so our brains never evolved the capacity to imagine them. It is probably significant that our own body size of a few feet is roughly in the middle of the range of sizes we can imagine. And our own lifetime of a few decades is roughly in the middle of the range of times we can imagine. "

" The people of jewel," said Olga Ciavolga," treat their children like delicate flowers. They think they will not survive without constant protection. But there are parts of the world where young boys and girls spend weeks at a time with no company except a herd of goats. They chase away wolves. They take care of themselves, and they take care of the herd. And so, when hard times come - as they always do in the end - those children are resourceful and brave. If they have to walk from one end of the county to the other, carrying their baby brother and sisters, they will do it. If they have to hide during the day and travel at night to avoid soldiers, they will do it. They do not give up easily." The tunnel took a sharp right-hand turn and, for a moment, the old woman s voice was lost. Something dropped onto Goldie's arm, and she opened her mouth to yelp - and thought of those children carrying their baby brothers and sisters through the night - and closed her mouth and kept going. She rounded the corner in time to hear Olga Ciavolga murmur," Of course, I am not saying that it is a good thing to give children such heavy responsibility's. They must be allowed to have a childhood. But they must also be allowed to find their courage and their wisdom, and learn when to stand and when to run away. After all, if they are not permitted to climb the trees, how will they ever see the great and wonderful world that lies before them? "

" Red is such an interesting color to correlate with emotion, because it’s on both ends of the spectrum. On one end you have happiness, falling in love, infatuation with someone, passion, all that. On the other end, you’ve got obsession, jealousy, danger, fear, anger and frustration. All those emotions — spanning from intense love, intense frustration, jealousy, confusion, all of that — in my mind, all those emotions are red. You know, there’s nothing in between. There’s nothing beige about any of those feelings, it all comes back to me, and it’s red. "

" Okay, I've only just found out the final lineup for Slytherin," said Angelina, consulting a piece of parchment. " Last year's Beaters, Derrick and Bole, have left now, but it looks as though Montague's replaced them with the usual gorillas, rather than anyone who can fly particularly well. They're two blokes called Crabbe and Goyle. I don't know much about them--" " We do," said Harry and Ron together." Well they don't look bright enough to tell one end of a broom from another," said Angelina, pocketing her parchment, " but then I was always surprised Derrick and Bole managed to find their way onto the pitch without signposts." " Crabbe and Goyle are in the same mold," Harry assured her. "

" A normal existence - what could be more irrational? It's fantastic the number of things you're forced not to think about in order to go from one end of the day to the other without jumping the track! And the number of memories that have to be driven from your mind, and truths that have to be evaded! " That's why I'm afraid to leave,' I said to myself. In Paris, near Robert, I manage without too much difficulty to avoid the traps; I carefully mark them, and there are alarm bells to warn me of dangers. But alone, under an unknown sky, what would happen to me? What truths would come suddenly to blind me? What chasms would open before me? Oh yes, chasms close, truths fade out - that is sure and certain; I've seen it happen often enough before. We're like those earthworms one vainly cuts in two, or those lobsters whose legs grow back again. But the moment of false agony, the moment you'd rather die than mend yourself once again - when I think of it, I lose heart. I try to reason with myself: 'Why should anything happen to me? But why shouldn't anything happen to me?' It's never safe to go off the beaten path. It's true, I feel a little stifled here, but you get used to being stifled. And a habit is never bad, despite what they say. "
