I have long believed that an experimentalist should not be unduely inhibited by theoretical untidyness. If he insists in having every last theoretical T crossed before he starts his research the chances are that he will never do a significant experiment. And the more significant and fundamental the experiment the more theoretical uncertainty may be tolerated. By contrast, the more important and difficult the experiment the more that experimental care is warranted. There is no point in attempting a half-hearted experiment with an inadequate apparatus.

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 (conjecture).

My purpose here is to denounce an idea which seems to be dangerous and false. ... Revolutionary trade unionists and orthodox communists are at one in considering everything that is purely theoretical as bourgeois. ... The culture of a socialist society would be a synthesis of theory and practice; but to synthesize is not the same as to confuse together; it is only contraries that can be synthesized. ... Marx’s principal glory is to have rescued the study of societies not only from Utopianism but also and at the same time from empiricism. ... Humanity cannot progress by importing into theoretical study the processes of blind routine and haphazard experiment by which production has so long been dominated. ... The true relation between theory and application only appears when theoretical research has been purged of all empiricism.
Simone Weil
In this very special form, feedback became part of the jargon of Group Dynamics, which has also assumed many of the characteristics of a cult in the efforts made to conserve some of the rigor of procedure with which Kurt Lewin and the experimentalist, Alex Bavelas, had attempted to imbue it. In this case, far from serving as a catalyzing, high-level theoretical tool, the term feedback has become a jargon-catchall for any kind of report back to government, management, the subjects of an experiment, subjects during an experiment, and so on. Stripped of its intellectual potential, the term knocks about the corridors of Unesco and for the most part those who use it have no idea that this bit of enjoined, Group Dynamic-recommended behavior is in any way related to the forbidding cross-disciplinary integration known as cybernetics.
Margaret Mead
Experimental science is a craft and an art, and part of the art is knowing when to end a fruitless experiment. There is a danger of becoming obsessed with a fruitless experiment even if it goes nowhere.
Martin Lewis Perl
What Mach calls a thought experiment is of course not an experiment at all. At bottom it is a grammatical investigation.
