Quotes About Theory

If we try to make general inferences about the theoretical possibility of a reliable computational model of the brain, we ought indeed to come to terms with the mysteries of quantum theory.

What is particularly curious about quantum theory is that there can be actual physical effects arising from what philosophers refer to as counterfactuals-that is, things that might have happened, although they did not in fact happen.

My own view is that to understand quantum nonlocality we shall require a radical new theory. This new theory will not just be a slight modification of quantum mechanics but something as different from standard quantum mechanics as general relativity is from Newtonian gravity. It would have to be something which has a completely different conceptual framework.

Democracy is beautiful in theory; in practice it is a fallacy. You in America will see that some day. —Benito Mussolini Dictators ride to and fro upon tigers which they dare not dismount. And the tigers are getting hungry. —Winston Churchill

The purpose of the present study is to bring, so far as we are able, some "order and lucidity" into the presently uncoordinated field of anxiety theory.

Bloom identified a sequence of six learning objectives that he felt moved from lower-order to higher-order thinking: knowledge, comprehension, application, analysis, synthesis, and evaluation. However, these ideas were just a theory and were not based on research on learning. Nonetheless, they have become codified into the way many teachers are taught to think about thinking.

As Einstein said years later, talking to Sir Herbert Samuel in the grounds of Government House, Jerusalem: "If Michelson-Morley is wrong, then relativity is wrong.

If the proletariat came to power, it could draw from Bernstein's theory the following 'practical' conclusion: to go to sleep.

The modern proletarian class doesn't carry out its struggle according to a plan set out in some book or theory; the modern workers' struggle is a part of history, a part of social progress, and in the middle of history, in the middle of progress, in the middle of the fight, we learn how we must fight...

The joys of theory are the sweetest intellectual pleasures of life

Christianity is not a doctrine, not, I mean, a theory about what has happened & will happen to the human soul, but a description of something that actually takes place in human life.

I have always thought that Darwin was wrong: his theory doesn't account for all this variety of species. It hasn't the necessary multiplicity. Nowadays some people are fond of saying that at last evolution has produced a species that is able to understand the whole process which gave it birth. Now that you can't say. [Drury, Conversation with Wittgenstein, p174]

Goethe's theory of the constitution of colours of the spectrum has not proved to be an unsatisfactory theory, rather it really isn't a theory at all. Nothing can be predicted with it. It is, rather a vague schematic outline of the sort we find in James's psychology. Nor is there any experimentum crucis which could decide for or against the theory.

The object of philosophy is the logical clarification of thoughts. Philosophy is not a theory but an activity. A philosophical work consists essentially of elucidations.

In other words, to put it into Euclid, or old-fashioned plane geometry, a straight line is not the shortest distance between two points.

Freedom is a terrible gift, and the theory behind all dictatorships is that the people do no want freedom.

I like here to think of another Fred, the eminent British scientist Fred Hoyle, and his theory of the universe, in which matter is continuously being created, with the universe expanding but not dissipating. As island galaxies rush away from each other into eternity, new clouds of gas are condensing into new galaxies. As old stars die, new stars are being born. Mr. Melcher lived in this universe of continuous creation and expansion.

As anyone who has ever started with a high concept and then worked backward to find numbers to fit the theory knows, it is not unusual for the theory to make a lot of sense "in hindsight.

Broken Windows theory and the Power of Context are one and the same. They are both based on the premise that an epidemic can be reversed, can be tipped, by tinkering with the smallest details of the immediate environment. This

Broken Windows theory and the Power of Context are one and the same. They are both based on the premise that an epidemic can be reversed, can be tipped, by tinkering with the smallest details of the immediate environment.

But is the commercial theory of learning true? Daniel Anderson says that new research suggests that children actually don't like commercials as much as we thought they did because commercials don't tell stories, and stories have a particular salience and importance to young people.

This is an epidemic theory of crime. It says that crime is contagious—just as a fashion trend is contagious —that it can start with a broken window and spread to an entire community.
