In the methodology of scientific research programs (MSRP) there are important features on the problem of prediction, especially regarding novel facts. In his approach, Imre Lakatos proposed three different levels on prediction: aim, process, and assessment. Chapter 5 pays attention to the characterization of prediction in the methodology of research programs. Thus, it takes into account several features: (1) its pragmatic characterization, (2) the logical perspective as a proposition, (3) the epistemological component, (4) its role in the appraisal of research (...) programs, and (5) its place as a value for scientific research. -/- The notion of “novel facts” is highly relevant in his conception, where several aspects are involved: the directions of novel facts, the different kinds of novelty, and the transition from six possible options of “novel facts” to four choices. Thereafter, the prediction of novel facts as the criterion of appraisal is considered. On the one hand, this requires analyzing the theoretical, empirical, and heuristic possibilities of appraisal; and, on the other, whether there is an overemphasis on the role of prediction in methodology of scientific research programs. As a consequence, there is an analysis of Lakatos’ criterion of appraisal in MSRP and economics. (shrink)

Although prima facie no more than a successful private detective, Sherlock Holmes is a classic exponent of scientific method and has laid down several fundamental rules of scientific discovery and truth?detection. While he rediscovered and modified well?known principles of induction, analysis and synthesis, and decision theory, he also made significant contributions to patterns of explanation, and with his ?principle of exclusion? was an ingenious innovator. This latter cornerstone of Holmes's methodology led him to an interesting modal theory of the ?improbable (...) possible? as a competitor to the famous doctrine of the ?impossible probable? put forward by Aristotle in de Arte Poetica. Holmes's scientific discipline was seasoned by warmth, understanding, and boldness. (shrink)

In The Poverty of Historicism, Popper claimed that because the growth of human knowledge cannot be predicted, the future course of human history is not foreseeable. For this reason, historicist theories like Marxism are unscientific or untrue. The aims of this article are: first, to reconstruct Poppers argument, second, to defend it against some critics, and third, to show that it is itself based a weak form of historicism.
