Hypothesis Quotes - page 5
Personally, I feel more irritated by a challenge to an accepted scientific theory than I do by an act of so-called "evil" or "injustice" among mankind; although I never allow my irritation to hamper my acceptance of the new theory as soon as positive evidence warrants it. Thus I have reluctantly exchanged the old nebular for the planetesimal hypothesis, and am beginning to accept the main points of relativity despite a profound intellectual distaste. What is, is-and our emotions regarding the cosmos and its phenomena are of no significance whatever, being wholly subjective matters dependent on individual accidents of neural and glandular physiology and of experience and environment.
H. P. Lovecraft
The story of a theory's failure often strikes readers as sad and unsatisfying. Since science thrives on self-correction, we who practice this most challenging of human arts do not share such a feeling. We may be unhappy if a favored hypothesis loses or chagrined if theories that we proposed prove inadequate. But refutation almost always contains positive lessons that overwhelm disappointment, even when [...] no new and comprehensive theory has yet filled the void.
Stephen Jay Gould
I adopt Mr. Darwin's hypothesis, therefore, subject to the production of proof that physiological species may be produced by selective breeding; just as a physical philosopher may accept the undulatory theory of light, subject to the proof of the existence of the hypothetical ether; or as the chemist adopts the atomic theory, subject to the proof of the existence of atoms; and for exactly the same reasons, namely, that it has an immense amount of primâ facie probability: that it is the only means at present within reach of reducing the chaos of observed facts to order; and lastly, that it is the most powerful instrument of investigation which has been presented to naturalists since the invention of the natural system of classification and the commencement of the systematic study of embryology.
Thomas Henry Huxley
Only two suppositions seem to be open to us - Either each species of crocodile has been specially created, or it has arisen out of some pre-existing form by the operation of natural causes.
Choose your hypothesis; I have chosen mine. I can find no warranty for believing in the distinct creation of a score of successive species of crocodiles in the course of countless ages of time.
Thomas Henry Huxley
I believe in clear-cut positions. I think that the most arrogant position is this apparent, multidisciplinary modesty of "what I am saying now is not unconditional, it is just a hypothesis," and so on. It really is a most arrogant position. I think that the only way to be honest and expose yourself to criticism is to state clearly and dogmatically where you are. You must take the risk and have a position.
Slavoj Žižek
Ether is, in effect, a merely hypothetical entity, valuable only in so far as it explains that which by means of it we endeavor to explain - light, electricity, or universal gravitation - and only so far as these facts cannot be explained in any other way. In like manner the idea of God is also an hypothesis, valuable only in so far as it enables us to explain that which by means of it we endeavor to explain - the essence and existence of the Universe - and only so long as these cannot be explained in any other way. And since in reality we explain the Universe neither better nor worse with this idea than without it, the idea of God, the supreme petitio principii, is valueless.
Miguel de Unamuno
There never was a sounder logical maxim of scientific procedure than Ockham's razor: Entia non sunt multiplicanda praeter necessitatem. That is to say; before you try a complicated hypothesis, you should make quite sure that no simplification of it will explain the facts equally well.
Charles Sanders Peirce
Is evolution a theory, a system or a hypothesis? It is much more: it is a general condition to which all theories, all hypotheses, all systems must bow and which they must satisfy henceforward if they are to be thinkable and true. Evolution is a light illuminating all facts, a curve that all lines must follow.
Pierre Teilhard de Chardin
Whereas reasons may, and usually do, figure among the proximate causes of belief, and thus play a part in both kinds of series (cognitive and causal), it is always possible to trace back the causal series to a point where every trace of rationality vanishes ; where we are left face to face with conditions of beliefs social, physiological, and physical- which, considered in themselves, are quite a-logical in their character. /.../ on any merely naturalistic hypothesis, the rational elements in the causal series lie always on the surface. Penetrate but a short way down, and they are found no more.
Arthur Balfour
Not only is it possible to devise complete models of the economy on hypotheses other than rationality, but in fact virtually every practical theory of macroeconomics is partly so based. The price- and wage- rigidity elements of Keynesian theory are hard to fit into a rational framework, though some valiant efforts have been made. ... But if the Keynesian model is a natural target of criticism by the upholders of universal rationality, it must be added that monetarism is no better. I know of no serious derivation of the demand for money from a rational optimization. ... The use of rationality in these arguments is ritualistic, not essential.
Kenneth Arrow
There is a philosophy that says that if something is unobservable -- unobservable in principle -- it is not part of science. If there is no way to falsify or confirm a hypothesis, it belongs to the realm of metaphysical speculation, together with astrology and spiritualism. By that standard, most of the universe has no scientific reality -- it's just a figment of our imaginations.
Leonard Susskind
The only part of evolution in which any considerable interest is felt is evolution applied to man. A hypothesis in regard to the rocks and plant life does not affect the philosophy upon which one's life is built. Evolution applied to fish, birds and beasts would not materially affect man's view of his own responsibilities except as the acceptance of an unsupported hypothesis as to these would be used to support a similar hypothesis as to man. The evolution that is harmful- distinctly so - is the evolution that destroys man's family tree as taught by the Bible and makes him a descendant of the lower forms of life. This ... is a very vital matter.
William Jennings Bryan
A famous thorny issue in philosophy is the so-called infinite regress problem. For example, if we say that the properties of a diamond can be explained by the properties and arrangements of its carbon atoms, that the properties of a carbon atom can be explained by the properties and arrangements of its protons, neutrons and electrons, that the properties of a proton can be explained by the properties and arrangements of its quarks, and so on, then it seems that we're doomed to go on forever trying to explain the properties of the constituent parts. The Mathematical Universe Hypothesis offers a radical solution to this problem: at the bottom level, reality is a mathematical structure, so its parts have no intrinsic properties at all!
Max Tegmark
This implication of the Mathematical Universe Hypothesis is pretty radical, so please pause your reading for a moment to take it in and think about it. What you're aware of right at this moment feels not like a photo but like a movie clip. This movie isn't reality-it exists only in your head, as part of your brain's reality model. It contains lots of information about the actual external physical reality-as long as you aren't dreaming or hallucinating-but still constitutes only a very heavily edited version of reality, akin to the evening news on TV, mainly featuring certain highlights of patterns nearby in space and time that your brain thinks are useful for you to be aware of.
