@parados,
I've already argued that, in that every axiom upon which an argument, scientific hypothesis etc... is based is necessarily developed from an ideal as there is no empirical evidence for an axiom and all arguments are based on them even empirical arguments.
Paul Feyerabend covers this nicely in
Against method
http://plato.stanford.edu/entries/feyerabend/
Against Method explicitly drew the “epistemological anarchist” conclusion that there are no useful and exceptionless methodological rules governing the progress of science or the growth of knowledge. The history of science is so complex that if we insist on a general methodology which will not inhibit progress the only “rule” it will contain will be the useless suggestion: “anything goes”. In particular, logical empiricist methodologies and Popper's Critical Rationalism would inhibit scientific progress by enforcing restrictive conditions on new theories. The more sophisticated “methodology of scientific research programmes” developed by Lakatos either contains ungrounded value-judgements about what constitutes good science, or is reasonable only because it is epistemological anarchism in disguise. The phenomenon of incommensurability renders the standards which these “rationalists” use for comparing theories inapplicable. The book thus (understandably) had Feyerabend branded an “irrationalist”. At a time when Kuhn was downplaying the “irrationalist” implications of his own book, Feyerabend was perceived to be casting himself in the role others already saw as his for the taking. (He did not, however, commit himself to political anarchism. His political philosophy was a mixture of liberalism and social democracy).
He later said:
One of my motives for writing Against Method was to free people from the tyranny of philosophical obfuscators and abstract concepts such as “truth”, “reality”, or “objectivity”, which narrow people's vision and ways of being in the world. Formulating what I thought were my own attitude and convictions, I unfortunately ended up by introducing concepts of similar rigidity, such as “democracy”, “tradition”, or “relative truth”. Now that I am aware of it, I wonder how it happened. The urge to explain one's own ideas, not simply, not in a story, but by means of a “systematic account”, is powerful indeed. (pp. 179–80).
