[It includes] Grammar [which] is "the science of speaking and writing correctly-the starting point of all liberal studies."

Grammar and logic free language from being at the mercy of the tone of voice. Grammar protects us against misunderstanding the sound of an uttered name; logic protects us against what we say have double meaning.

Water is two parts hydrogen and one part oxygen. What if someone says, “Well, that’s not how I choose to think about water.”? All we can do is appeal to scientific values.

Let the Spirit be lacking, and there may be wisdom of words, but not the wisdom of God; the powers of oratory, but not the power of God; the demonstration of argument and the logic of the schools, but not the demonstration of the Holy Spirit, the all-convincing logic of His lightning flash, such as convinced Saul before the Damascus gate. When the Spirit was outpoured the disciples were all filled with power from on high, the most unlettered tongue could silence gainsayers, and with its new fire burn its way through obstacles as flames fanned by mighty winds sweep through forests.

What sets imperialism of the capitalist sort apart from other conceptions of empire is that it is the capitalist logic that typically dominates, though ... there are times in which the territorial logic comes to the fore.

And what does endless capital accumulation imply for the territorial logics of power?

Poets do not go mad; but chess-players do. Mathematicians go mad, and cashiers; but creative artists very seldom. I am not, as will be seen, in any sense attacking logic: I only say that this danger does lie in logic, not in imagination.

The main condition is that the spiritual ear should be open to overhear and patiently take in, and the will ready to obey that testimony which, I believe, God bears in every human heart, however dull, to those great truths which the Bible reveals.

How do you get from, "We do not know whether this is protectable human life," to "Therefore, we will not protect it?" Wouldn't the logic just as likely (some would say far more likely) be, "Since we do not know whether this is protectable human life, therefore we will protect it?" Why does the judicial uncertainty about the humanity of the unborn lead to unbridled license to destroy it?

It is probably true that almost all atheists stand for the values of reason and freethought. I will attempt to put these values in more substantial terms.

When I began my career as a cosmologist some twenty years ago, I was a convinced atheist. I never in my wildest dreams imagined that one day I would be writing a book purporting to show that the central claims of Judeo-Christian theology are in fact true, that these claims are straightforward deductions of the laws of physics as we now understand them. I have been forced into these conclusions by the inexorable logic of my own special branch of physics.

My father was very political. But he told me, "Be very careful when you get into politics, because there's no black and white. There's an in-between in everything. So look at that side, don't take one point, because then you are negating half of the other people. Try to find the logic on a problem, something that you believe, and take the position that you believe, but be very careful about it." So I was very well trained in that aspect.

I'm pure geek, pure logic.

I've already written a section in the annual report for next year explaining why I think in one case that the figures on our balance sheet as calculated are wrong. But it's the standard way of doing it. It's holy writ. The SEC wants us to do it that way, and we'll do it that way, and I'll explain why I think it's wrong and shareholders can read it and see whether they agree with my logic or don't.

Forever I shall be a stranger to myself. In psychology as in logic, there are truths but no truth.

People who are unable to use their hands skillfully for all kinds of work, will not become good thinkers and will behave awkwardly in life. It is not the head alone, but the whole human being that is a logician. Activities demanding manual and bodily skill, such as knitting, leads to the enhancement of the faculty of judgment. This faculty is actually developed least of all by exercises in logic.

When money, instead of man, is at the center of the system, when money becomes an idol, men and women are reduced to simple instruments of a social and economic system, which is characterized, better yet dominated, by profound inequalities. So we discard whatever is not useful to this logic; it is this attitude that discards children and older people, and is now affecting the young.

I'm a logic monster, if things don't make sense I gotta make sense of them.

Writing is more than just the making of a series of comprehensible statements: it is the gathering in of connotations; the harvesting of them, like blackberries in a good season, ripe and heavy, snatched from among the thorns of logic.

In life, particularly in public life, psychology is more powerful than logic.

I perceive the world in fragments. It is somewhat like being on a very fast train and getting glimpses of things in strange scales as you pass by. A person can be very, very tiny. And a billboard can make a person very large. You see the corner of a house or you see a bird fly by, and it's all fragmented. Somehow, in painting I try to make some logic out of the world that has been given to me in chaos. I have a very pretentious idea that I want to make life, I want to make sense out of it. The fact that I am doomed to failure - that doesn't deter me in the least.

Anything that contradicts experience and logic should be abandoned.

I still partially suffer from the delusion that if you explain things logically and systematically, most people will abandon their emotional prejudices and respond to logic. But I don't suffer from that delusion as wholeheartedly as I did in the past. So if there's a fundamental difference, it's that I've accepted the fact that most imbeciles will never 'get' me and I shouldn't allow myself to get so upset about it.

I got out of the elevator and confronted Mr. Wexler. “Killing is wrong.” “We kill chickens,” Mr. Wexler said. “We kill cows. We kill trees. So big deal, we kill some drug dealers.” It was hard to argue with that kind of logic because I like cows and chickens and trees much better than drug dealers.

My brother used to say that when you deal with women, it's difficult to remove emotions from an argument. I never really knew what he meant.

Once there was Louis Armstrong blowing his beautiful top in the muds of New Orleans; before him the mad musicians who had paraded on official days and broke up their Sousa marches into ragtime. Then there was swing, and Roy Eldridge, vigorous and virile, blasting the horn for everything it had in waves of power and logic and subtlety - leaning into it with glittering eyes and a lovely smile and sending it out broadcast to rock the jazz world.

My Father taught me how to be a man – and not by instilling in me a sense of machismo or an agenda of dominance. He taught me that a real man doesn’t take, he gives; he doesn’t use force, he uses logic; doesn’t play the role of trouble-maker, but rather, trouble-shooter; and most importantly, a real man is defined by what’s in his heart, not his pants.
