“Facts do not "speak for themselves." They speak for or against competing theories. Facts divorced from theory or visions are mere isolated curiosities.”

“Even though it is, properly speaking, a postprediction, in the sense that the experiment was made before the theory, the fact that gravity is a consequence of string theory, to me, is one of the greatest theoretical insights ever.”

“Public administration is a process or a theory, not merely an accumulation of detailed facts. It is Verwaltungslehre.”

Marshall E. Dimock (1903–1991) American writer

The object of administrative study should be to discover, first, what government can properly and successfully do, and secondly, how it can do these proper things with the utmost possible efficiency and at the least possible cost both of money and of energy.

“Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts do not go away while scientists debate rival theories for explaining them. Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air pending the outcome. And human beings evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other, yet to be discovered. […] Evolutionists make no claim for perpetual truth, though creationists often do (and then attack us for a style of argument that they themselves favor). In science, “fact” can only mean “confirmed to such a degree that it would be perverse to withhold provisional assent.””

Stephen Jay Gould book Hen's Teeth and Horse's Toes

I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms.

“No matter which comes first, the facts or the theory, the question to be addressed is the extent to which the theory is borne out by the facts. The strongest possible claim would be that the theory can be logically derived from the facts. That is, given the facts, the theory can be proven as a consequence of them. This strong claim cannot be substantiated.”

“Even facts become fictions without adequate ways of seeing "the facts". We do not need theories so much as the experience that is the source of the theory.”

Ronald David Laing book The Politics of Experience

Ch. 1 : Experience as evidence http://www.marxists.org/reference/subject/philosophy/works/en/laing.htm
The Politics of Experience (1967)
Context: Even facts become fictions without adequate ways of seeing "the facts". We do not need theories so much as the experience that is the source of the theory. We are not satisfied with faith, in the sense of an implausible hypothesis irrationally held: we demand to experience the "evidence".
We can see other people's behaviour, but not their experience. This has led some people to insist that psychology has nothing to do with the other person's experience, but only with his behaviour.
The other person's behaviour is an experience of mine. My behaviour is an experience of the other. The task of social phenomenology is to relate my experience of the other's behaviour to the other's experience of my behaviour. Its study is the relation between experience and experience: its true field is inter-experience.
