A theory of syllogistic reasoning is proposed, derived from the medieval doctrine of 'distribution of terms'. This doctrine may or may not furnish an adequate ground for the logic of the syllogism but does appear to illuminate the psychological processes involved. Syllogistic thinking is shown to have its origins in the approach and avoidance behaviour of pre-verbal organisms and, in verbal (human) organisms, to bridge the gap between the intuitive grasp shown by most of us of the validity of simple (...) logical arguments and the failure of intuition in more complex arguments that require resort to calculation. Some difficulties are considered affecting the use of syllogisms as experimental material. These include failure on the part of the investigator to take account of the fact that a syllogism is always part of a continuing argument in which the topic of the argument is known to all parties and the possibility that subjects may find ways of appearing to solve syllogisms without actually doing so.

The essay replies to comments by Finnis, Gardner and Endicott, on my book, Law as a Moral Idea. It is questioned whether Finnis is right to suggest that governance by law is a requirement of justice. It is suggested that Hart's positivism may have rested upon an unduly private conception of morality. Gardner's suggestion that Law as a Moral Idea falsely manufactures disagreement with Hart is rejected, principally by pointing out that Gardner focuses upon only one issue, where the book (...) already acknowledges that Hart might conceivably agree, and ignores other issues where the disagreement with Hart seems indisputable. In response to Endicott, it is acknowledged that 'politics' could be understood as a moral idea comparable to the idea of 'law', but denied that this robs either thesis of interest. The nature of doctrinal reasoning and law's justificatory force is then discussed. (shrink)

This second edition has been revised to provide additional coherence to the themes examined and introduces sections on topical issues, for example the chapter on Utilitarianism now includes a discussion on law and economics.

This chapter contains sections titled: Problems of Jurisprudence The Enterprise of Legal Theory From Positivism to Natural Law Theory as Interpretation Law as Integrity Unger and the Critical Legal Studies Movement Philosophical Reconstruction of Legal Doctrine.

H.L.A. Hart’s legal positivism displaces the authority of institutions and emphasizes the independence of personal moral judgment. While such a position has an obvious appeal, we should not fail to acknowledge the extent to which values are articulated within established practices. In this essay, civility and law are offered as examples of practices that embody distinctive values and can properly be understood only by reference to such values. It is suggested that legal positivism is driven by a moral metaphysic wherein (...) abstractly conceived principles confront neutrally described facts. But values cannot, without distortion, be understood in abstraction from the practices and forms of association within which they find expression. The refusal to recognize this fact fosters moral skepticism rather than individual moral responsibility. (shrink)
