Nothing is text but what is spoken of in the Bible and meant there for person and place; the rest is application; which a discreet man may do well; but it is his scripture, not the Holy Ghost's. First, in your sermons use your logic, and then your rhetoric; rhetoric without logic is like a tree with leaves and blossoms, but no root.

If pressed to supplement Tweedledee's ostensive definition of logic with a discursive definition of the same subject, I would say that logic is the systematic study of the logical truths. Pressed further, I would say that a sentence is logically true if all sentences with its grammatical structure are true. Pressed further still, I would say to read this book.

The professor husband of a friend of mine has likened children to the insane. I often think of it. He says that children live on the edge of madness, that their behavior, apparently unmotivated, shares the same dream logic as crazy people's. I see what he means, and because I've learned to be patient with children, to tease out the logic that's always somewhere there, and irrefutable once explained.

Poincaré was a vigorous opponent of the theory that all mathematics can be rewritten in terms of the most elementary notions of classical logic; something more than logic, he believed, makes mathematics what it is.

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.

Structure that really pays off is all based on emotion. I don't write down an elaborate plan. It's really done by feel. It's one area of my writing that I think I've got surer at as I've evolved. In my work you often get an abrupt shift in time, a jolt. But the emotional logic will take the reader on. I hope. I trust. After all, our memories do not work with any sequential logic.

Logic is immaturity weaving its nets of gossamer wherewith it aims to catch the behemoth of knowledge. Logic is a crutch for the cripple, but a burden for the swift of foot and a greater burden still for the wise.

Murder is a horror, but an often necessary horror, never criminal, which it is essential to tolerate in a republican State. Is it or is it not a crime? If it is not, why make laws for its punishment? And if it is, by what barbarous logic do you, to punish it, duplicate it by another crime?

It's the unlikely juxtaposition of creativity and logic which causes the wooliness and confusion around the term 'innovation'. Everybody wants to be innovative; many companies and ideas are proclaimed to be innovative and no one doubts that innovation is a money spinner. And, thus, we are all looking for the magic formula. Well, here you go: Creativity + Iterative Development = Innovation.

A nervous excitability, a chronic exaltation of the passion, in which commingle the inferior life of the individual and its exterior manifestations, a state in which sentiment, idea, and will are confounded together, where for the lack of the powerful corrective of logic, the flights of imagination know no bounds, where life and human activity are deprived of a regulator, and move outside of material and concrete factors, by the sole interior force of the soul.

What the teacher does is sweep all of the logic, order and reason onto one side and make that side very strong.

What I love about directing is finding common ground in complementary palate with wardrobe, set design, the camera department, the makeup department, et cetera. I love figuring out that synergy. To have everything work in concert is amazing, I love working with that kind of logic. Directing is a cavalcade of taste decisions - this one or that one, but I raather enjoy it and am in the process of setting up the next endeavor.

What Artistic and Scientific Experience Have in Common - Where the world ceases to be the scene of our personal hopes and wishes, where we face it as free beings admiring, asking, and observing, there we enter the realm of Art and Science. If what is seen and experienced is portrayed in the language of logic, we are engaged in science. If it is communicated through forms whose connections are not accessible to the conscious mind but are recognized intuitively as meaninful, then we are engaged in art. Common to both is the loving devotion to that which transcends personal concerns and volition.

The theatre has always been to me a place where beautiful lies are told, and playwrighting the orchestration of platitudes around a central flaw in logic or a ridiculous idea. Acting — the disguise and impersonation — is an art of deception.

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.

The only rule was that the stuff had to be funny and pretty short. To me, the quintessential Army Man joke was one of John Swartzwelder's: 'They can kill the Kennedys. Why can't they make a cup of coffee that tastes good?' It's a horrifying idea juxtaposed with something really banal-and yet there's a kind of logic to it. It's illuminating because it's kind of how Americans see things: Life's a big jumble, but somehow it leads to something I can consume. I love that.

Mankind has moved away from the heart of the world to the logic of the mind, and their belief is in the chemist, the physicist, and the mathematician. Science has proven to them that all this ancient belief in ceremony is simply ignorance.

Whenever humanity seems condemned to heaviness, I think I should fly like Perseus into a different space. I don't mean escaping into dreams or into the irrational. I mean that I have to change my approach, look at the world from a different perspective, with a different logic and with fresh methods of cognition and verification.

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.

First, those who disagree with market efficiency simply assert that it stands to common sense that greater effort to get facts and greater acumen in analyzing those facts will pay off in better performance somehow measured. (By this logic, cure for cancer must have been found by 1955).

State censorship presents itself as a bulwark between society and forces of subversion or moral corruption. To dismiss this account of its own motives by the state as insincere would be a mistake: it is a feature of the paranoid logic of the censoring mentality that virtue ... must be innocent, and therefore, unless protected, vulnerable to the wiles of vice.

So how do theists respond to arguments like this? [The Argument from Evil] They say there is a reason for evil, but it is a mystery. Well, let me tell you this: I'm actually one hundred feet tall even though I only appear to be six feet tall. You ask me for proof of this. I have a simple answer: it's a mystery. Just accept my word for it on faith. And that's just the logic theists use in their discussions of evil.

The decision-makers should communicate the customer pictures and the logic of the strategies and actions. That communication allows employees throughout the organization to implement the strategies and actions, tweaking them appropriately in response to variations in the marketplace. It also allows employees to recognize information in the marketplace that contradicts the customer pictures, either because the pictures were not entirely correct or because customers have changed.

Perhaps there really are managers who can outperform the market consistently - logic would suggest that they exist. But they are remarkably well-hidden.
