„Men follow their sentiments and their self-interest, but it pleases them to imagine that they follow reason. And so they look for, and always find, some theory which, a posteriori, makes their actions appear to be logical. If that theory could be demolished scientifically, the only result would be that another theory would be substituted for the first one, and for the same purpose.“
— Vilfredo Pareto, livro Manual of Political Economy
Manual of Political Economy, page 95.
„For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.“

„It is man's highest interest not to violate, or attempt to violate, the rules which Infinite Wisdom has laid down.“
— Thomas Jackson Confederate general 1824 - 1863
Misattributed, Context: It is man's highest interest not to violate, or attempt to violate, the rules which Infinite Wisdom has laid down. The means by which men are to attain great elevation may be classed in three divisions — physical, mental, and moral. Whatever relates to health, belongs to the first; whatever relates to the improvement of the mind, belongs to the second. The formation of good manners and virtuous habits constitutes the third.
„The Steady State theory was what Karl Popper would call a good scientific theory: it made definite predictions, which could be tested by observation, and possibly falsified. Unfortunately for the theory, they were falsified.“

„We look upon economic theory as a sequence of conceptual models that seek to express in simplified form different aspects of an always more complicated reality.“

„The first task of administrative theory is to develop a set of concepts that will permit the description, in terms relevant to the theory, of administrative situations. These concepts, to be scientifically useful, must be operational; that is, their meanings must correspond to empirically observable facts or situations.“

Unended Quest: An Intellectual Autobiography (1976), Unsourced variant: Evolution is not a fact. Evolution doesn't even qualify as a theory or as a hypothesis. It is a metaphysical research program, and it is not really testable science. Popper later retracted his criticisms: I have changed my mind about the testability and logical status of the theory of natural selection; and I am glad to have an opportunity to make a recantation. :* "Natural selection and the emergence of mind" dialectica http://www.dialectica.ch/ Vol. 32 (1978), p. 339-355; republished in Evolutionary Epistemology, Rationality, and the Sociology of Knowledge (1987) edited by Gerard Radnitzky and W.

„People cited violation of the First Amendment when a New Jersey schoolteacher asserted that evolution and the Big Bang are not scientific and that Noah's ark carried dinosaurs. This case is not about the need to separate church and state; it's about the need to separate ignorant, scientifically illiterate people from the ranks of teachers.“

„I claim that the success of current scientific theories is no miracle. It is not even surprising to the scientific (Darwinist) mind. For any scientific theory is born into a life of fierce competition, a jungle red in tooth and claw. Only the successful theories survive—the ones which in fact latched onto the actual regularities in nature.“
