The author, known for his achievements in legal philosophy and methodology, has polished and refined this series of Lectures on the paradigms of legal thinking for over two decades. In their present form they introduce the reader to reasoning in law by leading him through the possibilities, boundaries and traps of assuming personal responsibility and impersonal pattern adoption that have arisen in the history of human thought and in the various legal cultures. The author seeks to disclose the actual processes hidden by the veil of patterns followed in thinking, processes that we encounter both in our conceptual-logical quests for certainties and in the undertaking of fertilising ambiguity. When trying to identify definitions lurking behind the human construct of facts, notions, logic and thinking, or behind the practice of giving meanings, he discovers tradition in our presuppositions, and the world-view and moral stance in our tacit agreements. Recognising the importance of the role communication plays in shaping society, he describes our existence and institutions as self-regulating processes. Since law is a wholly social venture, we not only take part in its oeuvre with our entire personality but are collectively responsible for its future.
