A Quote by Friedrich Nietzsche
It is certainly not the least charm of a theory that it is refutable; it is precisely thereby that it attracts the more subtle minds. It seems that the hundred-times-refuted theory of the "free will" owes its persistence to this charm alone; some one is always appearing who feels himself strong enough to refute it.

It is easy to obtain confirmations, or verifications, for nearly every theory-if we look for confirmations. Confirmations should count only if they are the result of risky predictions... A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice. Every genuine test of a theory is an attempt to falsify it, or refute it.
Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory.

It's a sort of bloom on a woman. If you have it, you don't need to have anything else, and if you don't have it, it doesn't much matter what else you have. Some women, the few, have charm for all; and most have charm for one. But some have charm for none.
Charm is often despised but I can never see why. No one has it who isn't capable of genuinely liking others, at least at the actual moment of meeting and speaking. Charm is always genuine; it may be superficial but it isn't false.
The more evolutionary theory gets called an atheistic theory, the greater the risk that it will lose its place in public school biology courses in the United States. If the theory is thought of in this way, one should not be surprised if a judge at some point decides that teaching evolutionary theory violates the Constitutional principle of neutrality with respect to religion.
Creationists reject Darwin's theory of evolution on the grounds that it is "just a theory". This is a valid criticism: evolution is indeed merely "a theory", albeit one with ten billion times more credence than the theory of creationism - although, to be fair, the theory of creationism is more than just a theory. It's also a fairy story. And children love fairy stories, which is presumably why so many creationists are keen to have their whimsical gibberish taught in schools.
The 'harmonious world' theory .. will help dispel doubts in the international community about China's continued development and refute the absurd 'China threat theory'.
The scientific theorist is not to be envied. For Nature, or more precisely experiment, is an exorable and not very friendly judge of his work. It never says "yes" to a theory. In the most favorable cases it says "Maybe," and in the great majority of cases simply "No." If an experiment agrees with a theory it means for the latter "Maybe," and if it does not agree it means "No." Probably every theory will some day experience its "No" - most theories, soon after conception.
It often seems to me that's all detective work is, wiping out your false starts and beginning again." Yes, it is very true, that. And it is just what some people will not do. They conceive a certain theory, and everything has to fit into that theory. If one little fact will not fit it, they throw it aside. But it is always the facts that will not fit in that are significant.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.
'Charm' - which means the power to effect work without employing brute force - is indispensable to women. Charm is a woman's strength just as strength is a man's charm.

Success is not a matter of mastering subtle, sophisticated theory but rather of embracing common sense with uncommon levels of discipline and persistence.
There is the theory that all the living forms in the world have arisen from a single source which itself came from an inorganic form. This theory can be called the 'general theory of evolution,' and the evidence which supports this is not sufficiently strong to allow us to consider it as anything more than a working hypothesis.
