This collection contains studies on justice, juridical reasoning and argumenta tion which contributed to my ideas on the new rhetoric. My reflections on justice, from 1944 to the present day, have given rise to various studies. The ftrst of these was published in English as The Idea of Justice and the Problem of Argument (Routledge & Kegan Paul, London, 1963). The others, of which several are out of print or have never previously been published, are reunited in the present volume. As justice is, for me, the prime example of a "confused notion", of a notion which, like many philosophical concepts, cannot be reduced to clarity without being distorted, one cannot treat it without recourse to the methods of reasoning analyzed by the new rhetoric. In actuality, these methods have long been put into practice by jurists. Legal reasoning is fertile ground for the study of argumentation: it is to the new rhetoric what mathematics is to formal logic and to the theory of demonstrative proof. It is important, then, that philosophers should not limit their methodologi cal studies to mathematics and the natural sciences. They must not neglect law in the search for practical reason. I hope that these essays lead to be a better understanding of how law can enrich philosophical thought. CH. P.

This is the first book to bring together distinguished jurisprudential theorists, as well as up-and-coming scholars, to critically assess the nature of legal reasoning. The volume is divided into 3 parts: The first part, General Jurisprudence and Legal Reasoning, addresses issues at the intersection of general jurisprudence - those pertaining to the nature of law itself - and legal reasoning. The second part, Rules and Reasons, addresses two concepts central to two prominent types of theory of legal reasoning. The essays in the third and final part, Doctrine and Practice, delve into the mechanics of legal practice and doctrine, from a legal reasoning perspective.

Essays on the Doctrinal Study of Law is a summary of the author’s 40 years of research in the fields of civil law and the philosophy of law. The main focus is on the two main tasks in the doctrinal study of law: the interpretation and systematisation of legal norms. In this regard, Professor Aarnio deals with the theory of argumentation as well as with its foundations - i.e., with the ontology, epistemology and methodology of legal thinking - and develops the ideas that were first presented in The Rational as Reasonable (Kluwer 1987) in all of these dimensions. The work includes an updated discussion on the writings of Robert Alexy, Jûrgen Habermas, Ronald Dworkin and Alf Ross. A focal point of view concerns the distinction between positivism and non-positivism, in which the core of the criticism focuses on Scandinavian realism.

In Section 1, I outline the history of natural law theory, covering Plato, Aristotle, the Stoics and Aquinas. In Section 2, I explore two alternative traditions of natural law, and explain why these constitute rivals to the Aristotelian tradition. In Section 3, I go on to elaborate a via negativa along which natural law norms can be discovered. On this basis, I unpack what I call three 'experiments in being', each of which illustrates the cogency of this method. In Section 4, I investigate and rebut two seminal challenges to natural law methodology, namely, the fact/value distinction in metaethics and Darwinian evolutionary biology. In Section 5, I then outline and criticise the 'new' natural law theory, which is an attempt to revise natural law thought in light of the two challenges above. I conclude, in Section 6, with a summary and some reflections on the prospects for natural law theory.
