Hypothesis Quotes - page 4
In science, conjecture drives both experiment and theory for it is only by forming conjectures (hypotheses) that we can make the direction of our experiments and theories informed. If such and such is true, then I should be able to do this experiment and look for this particular result or I should be able to find this theoretical formulation. Conversely, experiment and theory drive conjecture. One makes a startling observation or has a sudden insight and begins to speculate on its significance and implications and to draw possible conclusions.

In conclusion, it appears to me that nothing can be more improving to a young naturalist, than a journey in distant countries. It both sharpens, and partly likewise allays that want and craving, which, as Sir J. Herschel remarks, a man experiences although every corporeal sense is fully satisfied. The excitement from the novelty of objects, and the chance of success, stimulate him to increased activity. Moreover as a number of isolated facts soon become uninteresting, the habit of comparison leads to generalization. On the other hand, as the traveller stays but a short space of time in each place, his descriptions must generally consist of mere sketches, instead of detailed observation. Hence arises, as I have found to my cost, a constant tendency to fill up the wide gaps of knowledge, by inaccurate and superficial hypotheses.
Charles Darwin
While it was long possible and sometimes tempting for physicists to deny the usefulness of the molecular hypothesis, we economists have the good luck of being some of the ‘molecules' of economic life ourselves, and of having the possibility through human contacts to study the behavior of other ‘molecules'.
Tjalling Koopmans
If by religion, we are understand sectarian dogmas, in which no two of them agree, then your exclamation on that hypothesis is just, "that this would be the best of all possible worlds, if there were no religion in it." But if the moral precepts, innate in man, and made a part of his physical constitution, as necessary for a social being, if the sublime doctrines of philanthropism and deism taught us by Jesus of Nazareth, in which all agree, constitute true religion, then, without it, this would be, as you again say, "something not fit to be named, even indeed, a hell."
Thomas Jefferson
My quotations from Newton suggest the motive which induced him to take a stand against the use of hypotheses, namely, the danger of becoming involved in disagreeable controversies. ...Newton could no more dispense with hypotheses in his own cogitations than an eagle can dispense with flight. Nor did Newton succeed in avoiding controversy.
Florian Cajori
If there was anything, anything more at all, after this crazy mix-up we call living, I could feel that there might be some point to the whole frantic business, even if I did not know and could not know the full answer while I was alive.”
"And suppose there was not? Suppose that when a man's body disintegrates, he himself disappears absolutely. I'm bound to say I find it a probable hypothesis.”
"Well- It wouldn't be cheerful knowledge, but it would be better than not knowing. You could plan your life rationally, at least. A man might even be able to get a certain amount of satisfaction in planning things better for the future, after he's gone. A vicarious pleasure in the anticipation.
Robert A. Heinlein
Our brains have evolved mainly to deal with our body and its interactions with the world it senses to be around us. Is this world real? This is a venerable philosophical issue and I do not wish to be embroiled in the finely honed squabbles to which it has led. I merely state my own working hypothesis: that there is indeed an outside world, and that it is largely independent of our observing it. We can never fully know this outside world, but we can obtain approximate information about some aspects of its properties by using our senses and our brain.
Francis Crick
The idea that a country's economic fortunes are largely determined by its success on world markets is a hypothesis, not a necessary truth; and as a practical, empirical matter, that hypothesis is flatly wrong. That is, it is simply not the case that the world's leading nations are to any important degree in economic competition with each other, or that any of their major economic problems can be attributed to failures to compete on world markets.
Paul Krugman
Central to the Smithian approach is our willingness to see critically what we observe around us. The sense of comfort that is often associated with being content with the world as it is can seriously hamper the pursuit of justice. This understanding goes strongly against a line of thought that was powerfully presented by Friedrich Nietzshe. ‘The Christian resolve to find the world ugly and bad has made the world ugly and bad', said Nietzshe. I think I can, with some effort, understand what Nietzsche meant, but it is hard for me, even with a lot of effort, to see that Nietzshe's hypothesis helps us to understand the causation or resilience of the nastiness of the world in which we live. Nor, I must insist (this I do as a thoroughly unreligious person), does it offer any obvious insight into the lives and achievements of Martin Luther King, or Mother Theresa, or Desmond Tutu, who have tried to reduce injustice in the world and have done so with non-negligible success.
Amartya Sen
It has been said, that the principle involved in the above and in similar applications is that of the equal distribution of our knowledge, or rather of our ignorance the assigning to different states of things of which we know nothing, and upon the very ground that we know nothing, equal degrees of probability. I apprehend, however, that this is an arbitrary method of procedure. Instances may occur, and one such has been adduced, in which different hypotheses lead to the same final conclusion.
George Boole
This consideration must alter the form of our proposed inquiry; for the question being thus at least partly decided, since it is ascertained that we have rays of heat which give no light, it can only become a subject of inquiry whether some of these heat-making rays may not have a power of rendering objects visible, superadded to their now already established power of heating bodies. This being the case, it is evident that the onus probandi [burden of proof] ought to lie with those who are willing to establish such an hypothesis, for it does not appear that Nature is in the habit of using one and the same mechanism with any two of our senses. Witness the vibration of air that makes sound, the effluvia that occasion smells, the particles that produce taste, the resistance or repulsive powers that affect the touch-all these are evidently suited to their respective organs of sense.
William Herschel
Should the believers in special creations consider it unfair thus to call upon them to describe how special creations take place, I reply that this is far less than they demand from the supporters of the Development Hypothesis. They are merely asked to point out a conceivable mode. On the other hand, they ask, not simply for a conceivable mode, but for the actual mode.
Herbert Spencer
That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved-who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";-for him to make a difficulty of the matter is inexcusable.
Herbert Spencer
Each form of the sacrosanct was regarded by members of the culture which gave rise to it as a revelation of the Truth; at Byzantium it was not a mere hypothesis that was sponsored by the majesty of the Byzantine style. To us, however, these forms make their appeal as forms alone - in other words, as they would be were they the work of a contemporary (and, since this actually is unthinkable, they affect us in a puzzling manner); or else as so many grandiose vestiges of a faith that has died out. We look at them from outside; they are still emotive, but they are no longer true. Thus we deprive them of what was their most vital element; for a religious civilization that regarded what it revered as a mere hypothesis is inconceivable.
André Malraux
Men without their choice derive benefits from that association; without their choice they are subjected to duties in consequence of these benefits; and without their choice they enter into a virtual obligation as binding as any that is actual. Look through the whole of life and the whole system of duties. Much the strongest moral obligations are such as were never the results of our option. I allow, that if no supreme ruler exists, wise to form, and potent to enforce, the moral law, there is no sanction to any contract, virtual or even actual, against the will of prevalent power. On that hypothesis, let any set of men be strong enough to set their duties at defiance, and they cease to be duties any longer.
Edmund Burke
