Summary In the attempt to understand science, definition is not much of a help. Due to the ever growing complexity of science, no unique and universally valid set of defining criteria is available. Hence, certain distinctions are resorted to: science is both a body of tested knowledge and a method of inquiry. The latter, in turn, consists of two phases: discovery and confirmation. The writer argues that it is mainly in respect of its method that science can best be characterized (...) and distinguished from other types of inquiry. (shrink)

I like to say there is no scientific method as such, but rather only the free and utmost use of intelligence.P.W. BridgmanIt is generally believed—see, for example, Lakatos, Dorling, Koertge, Gellner, and Finnocchiaro—that Feyerabend is committed to the view that science is an essentially irrational enterprise. In this paper, I argue initially that this is so only if Feyerabend is saddled with an unreasonable notion of rationality. Next, I point out, first, that there is a reasonable notion of rationality which (...) is compatible with Feyerabend's non-method ‘anything goes’; and, second, that unless coupled with some form of rationalism this non-method is obviously and trivially false.

Inference is a process by which appropriate belief states get connected. Belief states are biological states in the sense that they are reentrant loops ; their intrinsic feature is recognition. In inference or reasoning the transition process between belief states is regulated by the rule of concept usage, involved in the belief state, in natural language. Like belief states experiential states are also biological states whose extrinsic feature is recognition, such that, one can have an, say, X-type experience without recognizing (...) it as an experience of X. One can, however, also have an experience of an X; in the latter case, one not only has an X-type experience but also recognizes an X as an X. In some cases the transition from X-type experience to believing an X to be there instantiates a quasi-inferential pattern. In all such cases the transition process is regulated by the rule of X usage. In such quasi-inferential transition additional belief states are involved. Such states assert that there are no countervailing factors and there are additional factors conducive to the conclusion. Such belief states are expressed non-propositionally in the language of thought. Propositions are a necessary part of such quasi-inference for they give content to thoughts to which one can assign 'falsity' and defeasible reasoning requires us to assign 'falsity' to our thoughts. Propositions implicated in the quasi-inferences from experience types to belief states are the evidential reasons for the conclusion and they can only be accepted as provisionally true and have to be revised in the light of further information.
