„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.“

„The world in which we live can be understood as a result of muddle and accident; but if it is the outcome of a deliberate purpose, the purpose must have been that of a fiend. For my part, I find accident a less painful and more plausible hypothesis.“

—  Bertrand Russell logician, one of the first analytic philosophers and political activist 1872 - 1970
Context: It is only when we think abstractly that we have such a high opinion of man. Of men in the concrete, most of us think the vast majority very bad. Civilized states spend more than half their revenue on killing each other's citizens. Consider the long history of the activities inspired by moral fervour: human sacrifices, persecutions of heretics, witch-hunts, pogroms leading up to wholesale extermination by poison gases … Are these abominations, and the ethical doctrines by which they are prompted, really evidence of an intelligent Creator? And can we really wish that the men who practised them should live for ever? The world in which we live can be understood as a result of muddle and accident; but if it is the outcome of a deliberate purpose, the purpose must have been that of a fiend. For my part, I find accident a less painful and more plausible hypothesis. Essay Do We Survive Death? (1936)

„This tends to confirm the hypothesis that all are composed of stars more or less remote.“

—  William Herschel German-born British astronomer, technical expert, and composer 1738 - 1822
Context: Nebulæ can be selected so that an insensible gradation shall take place from a coarse cluster like the Pleiades down to a milky nebulosity like that in Orion, every intermediate step being represented. This tends to confirm the hypothesis that all are composed of stars more or less remote. Ch.4 "Life and Works"

„All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system.“

—  Ludwig Wittgenstein Austrian-British philosopher 1889 - 1951
Context: 105. All testing, all confirmation and disconfirmation of a hypothesis takes place already within a system. And this system is not a more or less arbitrary and doubtful point of departure for all our arguments; no it belongs to the essence of what we call an argument. The system is not so much the point of departure, as the element in which our arguments have their life.

„The hypothesis of God is a peculiar one, in that it supposes an infinitely incomprehensible object, although every hypothesis, as such, supposes its object to be truly conceived in the hypothesis.“

—  Charles Sanders Peirce American philosopher, logician, mathematician, and scientist 1839 - 1914
Context: The hypothesis of God is a peculiar one, in that it supposes an infinitely incomprehensible object, although every hypothesis, as such, supposes its object to be truly conceived in the hypothesis. This leaves the hypothesis but one way of understanding itself; namely, as vague yet as true so far as it is definite, and as continually tending to define itself more and more, and without limit. The hypothesis, being thus itself inevitably subject to the law of growth, appears in its vagueness to represent God as so, albeit this is directly contradicted in the hypothesis from its very first phase. But this apparent attribution of growth to God, since it is ineradicable from the hypothesis, cannot, according to the hypothesis, be flatly false. Its implications concerning the Universes will be maintained in the hypothesis, while its implications concerning God will be partly disavowed, and yet held to be less false than their denial would be. Thus the hypothesis will lead to our thinking of features of each Universe as purposed; and this will stand or fall with the hypothesis. Yet a purpose essentially involves growth, and so cannot be attributed to God. Still it will, according to the hypothesis, be less false to speak so than to represent God as purposeless. II
