“I stand four-square for reason, and object to what seems to me to be irrationality, whatever the source. If you are on my side in this, I must warn you that the army of the night has the advantage of overwhelming numbers, and, by its very nature, is immune to reason, so that it is entirely unlikely that you and I can win out. We will always remain a tiny and probably hopeless minority, but let us never tire of presenting our view, and of fighting the good fight for the right.”

“We would grow tired of it, Grandpa, if it were beautiful all the time. A little change from night to night is good for us.''For you, because you're young, Wanda. You have many, many evenings ahead of you. I don't. I want more good ones.”

“Do you know what it is to play a part? To split your personality deliberately for twenty-four hours a day? Even when with friends? Even when alone, so that you will never forget inadvertently? To be a dilettante? To be eternally amused? To be of no account? To be so effete and faintly ridiculous that you have convinced all who know you of your own worthlessness? All so that your life may be safe even though it means it has become barely worth living. But even so, once in a while I can fight them.”

“There is nothing your knife handlers can do in the way of rioting and demonstrating that will have any permanent effect as long as, in the extremity, there is an army equipped with kinetic, chemical, and neurological weapons that is willing to use them against your people. You can get all the downtrodden and even all the respectables on your side, but you must somehow win over the security forces and the Imperial army or at least seriously weaken their loyalty to the rulers.”

“We now know the basic rules governing the universe, together with the gravitational interrelationships of its gross components, as shown in the theory of relativity worked out between 1905 and 1916. We also know the basic rules governing the subatomic particles and their interrelationships, since these are very neatly described by the quantum theory worked out between 1900 and 1930. What's more, we have found that the galaxies and clusters of galaxies are the basic units of the physical universe, as discovered between 1920 and 1930....The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong...My answer to him was, when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together.The basic trouble, you see, is that people think that 'right' and 'wrong' are absolute; that everything that isn't perfectly and completely right is totally and equally wrong.However, I don't think that's so. It seems to me that right and wrong are fuzzy concepts, and I will devote this essay to an explanation of why I think so.When my friend the English literature expert tells me that in every century scientists think they have worked out the universe and are always wrong, what I want to know is how wrong are they? Are they always wrong to the same degree?”

“Fighting and scars are part of a trader's overhead. But fighting is only useful when there's money at the end, and if I can get it without, so much the sweeter.”

“I prefer rationalism to atheism. The question of God and other objects-of-faith are outside reason and play no part in rationalism, thus you don't have to waste your time in either attacking or defending.”
