One finds the truth by making a hypothesis and comparing observations with the hypothesis.
David Douglass

One must credit an hypothesis with all that has had to be discovered in order to demolish it.
Jean Rostand

Originally, in the early eighties, the drug hypothesis was among the first which occurred to scientists.
Serge Lang

Our working hypothesis is that the status of knowledge is altered as societies enter what is known as the postindustrial age and cultures enter what is known as the postmodern age.
Jean-Francois Lyotard

Probably the simplest hypothesis... is that there may be a slow process of annihilation of matter.
Arthur Eddington

Roughly speaking, this hypothesis asks whether drug use causes some of the diseases officially associated with AIDS, such as immunodeficiency and Kaposi's sarcoma.
Serge Lang

The fact that we don't keep repeating tests in the same arena is not because the probability of the hypothesis showing its falsity in other arenas goes up after it has passed tests in one arena.
Robert Nozick

The first and most important reason for its elimination is the unquestioned fact that evolution is not a science; it is a hypothesis only, a speculation.
William B. Riley

The great tragedy of science - the slaying of a beautiful hypothesis by an ugly fact.
Thomas Huxley

The greatest problem for mathematicians now is probably the Riemann Hypothesis.
Andrew Wiles

The hypothesis may be put forward, to be tested by the s subsequent investigation, that this development has been in large part a matter of the reciprocal interaction of new factual insights and knowledge on the one hand with changes in the theoretical system on the other.
Talcott Parsons

The hypothesis of surviving intelligence and personality - not only surviving but anxious and able with difficulty to communicate - is the simplest and most straightforward and the only one that fits all the facts.
Oliver Joseph Lodge

The materialistic point of view in psychology can claim, at best, only the value of an heuristic hypothesis.
Wilhelm Wundt

The only relevant test of the validity of a hypothesis is comparison of prediction with experience.
Milton Friedman

The shrewd guess, the fertile hypothesis, the courageous leap to a tentative conclusion - these are the most valuable coins of the thinker at work. But in most schools guessing is heavily penalized and is associated somehow with laziness.
Jerome Bruner

The word "belief" is a difficult thing for me. I don't believe. I must have a reason for a certain hypothesis. Either I know a thing, and then I know it - I don't need to believe it.
Carl Jung

There are two possible outcomes: if the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery.
Enrico Fermi

There is no justifiable prediction about how the hypothesis will hold up in the future; its degree of corroboration simply is a historical statement describing how severely the hypothesis has been tested in the past.
Robert Nozick

There's two possible outcomes: if the result confirms the hypothesis, then you've made a discovery. If the result is contrary to the hypothesis, then you've made a discovery.
Enrico Fermi

This, it may be said, is no more than a hypothesis... only of that force of precedent which in all times has been so strong to keep alive religious forms of which the original meaning is lost.
William Robertson Smith
