Feyerabend: a students perspective
Posted by El Sordo on January 18th, 2008Feyerabend was once labelled the ‘greatest enemy of science’ a title that in his later life he took pride in (he was an iconoclast by nature), but which midway through his career threw him into an enormous depression. The roots of his depression and the crass insults he had to suffer for daring to challenge the orthodox view of science were based substantially upon the misunderstanding of his work. One of the ‘problems’ with his writings is the speed with which he moves from clear point to reductio- thus without a careful reading his supporters and detractors often (myself included) end up reading the reductio as though it were his point of view. Consequently since his death with the major retrospective his work is enjoying – one philosopher going so far as to say that minus the iconoclasms he has been wholly rehabilitated – there has been a scramble to make sense of all of his work in its complexity. Subsequently a great deal of focus has been attached to the interpretations of his best students (themselves now noteworthy academics). What follows are some thoughts of Gonzalo Munevar – a one time student of Feyerabends – and now a Proffessor in his own right.
What are Feyerabends greatest contributions?
- Contrary to being an enemy of science Feyerabend showed how complex and humane science is and ought to be. Of his many contributions, perhaps the most important is that there is no method or rule that can capture science completely. The most excellent idea about the nature of science has to allow exceptions. When we look at the history of science, we discover not only that the great scientists violated the methods proposed by the empiricists, but that they had to violate them, otherwise they would not have secured the great successes through which we know them today.
- Until Feyerabend and Kuhn it was supposed that scientific rationality adhered to certain methodological rules. That science was a shining beacon of rationality. Those rules were inductive. The philosophical problem was that even though we “knew” that such scientific method produced knowledge, we could not prove it. Karl Popper argued that the problem came from thinking erroneously that induction was the method of science. We just needed to realize that science was based instead on the method of trial and error. But Feyerabend’s analysis of the history of science demonstrated that adherence to all proposed methods, from Francis Bacon’s to Popper’s, would impede the progress of science. To progress, then, science needs to act against method from time to time.
- The reason is very simple. All varieties of empiricism assume that experience determines the worth of our scientific ideas. This assumption is presumably justified because through experience scientists learn directly what is written on the book of nature. For example, if all observers see a stone fall vertically, the vertical motion of the stone is an immediate or direct truth given by observation – an immediate truth with which our most profound hypotheses about the world must agree. If a hypothesis implies that the stone does not fall vertically, our observations, our experience will then refute it. Unfortunately for empiricism, as Feyerabend reminds us, the Copernican hypothesis claims that the earth rotates on its axis to give us the day-night cycle, and this claim is refuted by the vertical fall of the stone.
- Munevar goes on to explain why this isnt a problem in the end for Galileo. We rejoin it after the explanation.
- These considerations do not imply that scientific hypotheses or theories always defeat the verdict of experience, but they do imply that such victories by theory are possible. This result implies in turn that all empiricist methodological rules must have exceptions. The reason is that such rules assign a higher priority to experience (over theory).
- Feyerabend rescued Galileo from the preposterous role of being the first and greatest hero of empiricism. By doing so, he allowed us to understand science very differently
What were Feyerabends errors?
- He erred in his proposal that all traditions or ideologies should have equal standing. But eventually he realized that, as Marguerite von Brentano had argued, the Nazis and the Quakers would then have equal access to pursue their goals, even though one of the Nazis’ main goals was to exterminate other cultures.
- He also acknowledged, though reluctantly, my criticism to the effect that a society has the obligation to teach its young the skills and the views they need to survive, and that in a world that depends on science that is what students will have to learn, not astrology or voodoo. He thus came to see that there were drastic limitations to his notion of the separation of science and society.
What influence did John Stuart Mill have?
John Stuart Mills essay On Liberty was a great influence to Feyerabend, Munevar explains how so, and why it is essential we see Feyerabend as part of this libertarian tradition (the better to understand his conclusions).
- Feyerabend points out that we are often unable to even discover important evidence against our favorite theories unless we consider seriously alternative theories that can propose and make sense of counter-evidence… No matter how certain we may be of a theory, a scientist who fails to accept it and develops instead a different theory is doing science a favor. For as Feyerabend says, “We need a dream-world in order to discover the features of the real world we think we inhabit (and which may actually just be another dream-world).”
- Feyerabend also acts against the important tradition of Plato and Descartes, whose obsession it was to discover the correct path to unique truth. Mill was the first important philosopher who rebelled against the goal itself. In his essay On Liberty, Mill argued that it does not favor society to force its members to accept the official point of view – no matter how certain it seems to be. By allowing the development of different points of view society profits, for if the official point of view is false, we gain the opportunity to replace with another that might be at least partially true. And if the official point of view turns out to be true anyway, comparing it with alternative points of view allow us to understand it better. Feyerabend’s accomplishment in this area comes from extending Mill’s philosophy to science.
- Feyerabend’s ironic sense of humor led him to proclaim anarchy in the philosophy of science and to suggest that “anything goes.” But he never offered anarchy as a sort of anti-method method. Anarchy is the description that a traditional rationalist would give to the way science should be done according to Feyerabend, and particularly the description that rationalist would give of pluralism. It is that rationalist who finds it obvious that rationality consists in behaving in accordance with the rules of the method of empiricism. And it is that rationalist who recoils in horror at the “anything goes” attitude in science a la Feyerabend.
