Discovery practices in natural sciences: from analogy to preduction

In this paper I face up to Charles Peirce's view that deduction can never originate any idea whatsoever. According to him new ideas come to science only by means of abduction. I affirm on my side that deductive reasoning can be extended to the context of discovery in mathematical physics. Thus a new form of discovery becomes recognizable. I call it preduction and I claim that it is the way by which many factual hypotheses, theoretical laws and theoretical models are anticipated in physics. I

The fallibility of abductive inferences was already recognized by Peirce himself. The fallibility of preductive inferences follows directly from the fact that the available background, on which the preductive way of reasoning grounds, can be not true. Since moreover many other creativity practices, like induction, analogy and serendipity, are worthy to be taken into consideration in the methodology of natural sciences, it becomes reasonable to assume the existence of a plurality of fallible strategies in scientific discovery.
