A close reading of Descartes’ works, particularly his Regulae ad Directionem Ingenii, calls into question the common interpretation of Peirce’s ‘Questions Concerning Certain Faculties Claimed for Man’ and ‘Some Consequences of Four Incapacities’ as being anti-Cartesian. In particular, Descartes’ conception of intuition differs from Peirce’s, and on one plausible reading of Descartes his intuitionism actually mirrors Peirce’s inferentialism in key respects. Given these similarities between Descartes and Peirce, the dogmatic status of the anti-Cartesian interpretation of Peirce becomes evident.

After a brief sketch of the history of philosophical pragmatism generally, and of legal pragmatism specifically (section 1), this paper develops a new, neo-classical legal pragmatism: a theory of law drawing in part on Holmes, but also on ideas from the classical pragmatist tradition in philosophy. Main themes are the "pluralistic universe" of law (section 2); the evolution of legal systems (section 3); the place of logic in the law (section 4); and the relation of law and morality (section 5).

Scientific evidence and scientific values under risk and uncertainty are strictly connected from the point of view of Peirce’s pragmaticism. In addition, economy and statistics play a key role in both choosing and testing hypotheses. Hence we may show also the connection between the methodology of the economy of research and statistical frequentism, both originating from pragmaticism. The connection is drawn by the regulative principles of synechism, tychism and uberty. These principles are values that have both epistemic and non-epistemic dimension. (...) They concern both the decisions to test a hypothesis as well as inductive risk. The validity of this result stems from the values cost–benefit analysis imposes on scientific inquiry. Values associated with the economy of research are important not only in the pre-test phases of generating hypotheses but also when hypotheses are effectively tested. Peirce took these economic considerations to leave room for an interpretation of probability which is not only a frequentist and propensity-theoretic but also a conceptualist one referring to degrees of belief. We show that this leeway nonetheless agrees with the theory of the economy of scientific methods. (shrink)
