Jealousy is the theory that some other fellow has just as little taste.
The worst censors are those prohibiting criticism of the theory of evolution in the classroom.
One of the most striking and fundamental things about probability theory is that it leads to an understanding of the otherwise strange fact that events which are individually capricious and unpredictable can, when treated en masse, lead to very stable average performances.
Contrary to conventional military and game theory, the most effective offense is sometimes a direct attack against your political opponent's greatest strength - not his weaknesses - to place him immediately on the defensive.
No theory is too false, no fable too absurd, no superstition too degrading for acceptance when it has become embedded in common belief. Men will submit themselves to torture and to death, mothers will immolate [burn] their children at the bidding of beliefs they thus accept.
The purpose of economic theory is to make those who are comfortable FEEL comfortable.
Frankly, these days, without a theory to go with it, I can't see a painting.
I am afraid that I do not hold with the theory of 'global warming' - there will always be climate change. . . . Big thing here is - do we know what we are doing that is bringing about climate change? At present the answer to this is NO.
I accept that climate change is a challenge, I accept the broad theory about global warming. I am sceptical about a lot of the more gloomy predictions.
There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.
For let us not underestimate the Christian: the Christian, false to the point of innocence, is far above the ape-regarding Christians, a well known theory of descent becomes a mere compliment.
The more we learn about life, the less plausible is any evolutionary theory that relies on blind, undirected, piece-by-piece change.
But just in proportion as this process of extermination has acted on an enormous scale, so must the number of intermediate varieties, which have formerly existed, be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and serious objection which can be urged against the theory. The explanation lies, as I believe, in the extreme imperfection of the geological record.
I am not at all convinced that human emissions of CO2 are adding to global warming. . . . I remain to be convinced about the theory of anthropogenic global warming.
Our theory is, if you need the user to tell you what you're selling, then you don't know what you're selling, and it's probably not going to be a good experience.
Experience by itself teaches nothing. . . Without theory, experience has no meaning. Without theory, one has no questions to ask. Hence, without theory, there is no learning.
I have a theory that you can make any sentence seem profound by writing the name of a dead philosopher at the end of it.
Playing music is not really susceptible to theory much. Circumstances affect it so much.
A professor must have a theory as a dog must have fleas.
Just read the farm relief bill. It's just a political version of Einstein's last theory. If a farmer could understand it, he certainly would know more than to farm. He would be a professor at Harvard.
