Theory Quotes
-
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.
-
It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.
-
Implication is thus the very texture of our web of belief, and logic is the theory that traces it.
-
The unphilosophical majority among men are the ones most helplessly dependent on their era's dominant ideas.

They know only what they have always been taught.

I can easily conceive, most Holy Father, that as soon as some people learn that in this book which I have written concerning the revolutions of the heavenly bodies, I ascribe certain motions to the Earth, they will cry out at once that I and my theory should be rejected.
-
The gospel of Jesus is not a rational concept to be explained in a theory of salvation, but a story about God’s presence in Jesus’ solidarity with the oppressed, which led to his death on the cross. What is redemptive is the faith that God snatches victory out of defeat, life out of death, and hope out of despair.
-
Kepler had to realize clearly that logical-mathematical theoretizing, no matter how lucid, could not guarantee truth by itself; that the most beautiful logical theory means nothing in natural science without comparison with the exactest experience. Without this philosophic attitude, his work would not have been possible.
-
On quantum theory I use up more brain grease than on relativity.
-
According to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature.
-
Quantum mechanics is certainly imposing. But an inner voice tells me that this is not yet the real thing. The theory says a lot, but does not bring us any closer to the secrets of the "Old One." I, at any rate, am convinced that He is not playing at dice.

-
Post-modernism ‘ironises’ out all questions of meaning. It reduces everything to the ‘been there, done that’ mentality, and shrinks the world to a theory of everything that can fit on a T-shirt. It lets us off the hook. We no longer have to be good, just good enough. It lowers the existential bar, and moves the metaphysical goal posts closer, or gets rid of them entirely.
-
Unfortunately for the good sense of mankind, the fact of their fallibility is far from carrying the weight in their practical judgement, which is always allowed to it in theory; for while every one well knows himself to be fallible, few think it necessary to take any precautions against their own fallibility.
-
I am just fascinated by music and I want to know how to identify all the things I love about it; to me music theory is like learning another language and then being able to explain how much you love something more clearly.

In the theory of psycho-analysis we have no hesitation in assuming that the course taken by mental events is automatically regulated by the pleasure principle. We believe, that is to say, that the course of those events is invariably set in motion by an unpleasurable tension, and that it takes a direction such that its final outcome coincides with a lowering of that tension that is, with an avoidance of unpleasure or a production of pleasure.
