The Handbook of the Logic of Argument and Inference is an authoritative reference work in a single volume, designed for the attention of senior undergraduates, graduate students and researchers in all the leading research areas concerned with the logic of practical argument and inference.After an introductory chapter, the role of standard logics is surveyed in two chapters. These chapters can serve as a mini-course for interested readers, in deductive and inductive logic, or as a refresher.Then follow two chapters of criticism; one the internal critique and the other the empirical critique. The first deals with objections to standard logics (as theories of argument and inference) arising from the research programme in philosophical logic. The second canvasses criticisms arising from work in cognitive and experimental psychology. The next five chapters deal with developments in dialogue logic, interrogative logic, informal logic, probability logic and artificial intelligence. The last chapter surveys formal approaches to practical reasoning and anticipates possible future developments. Taken as a whole the Handbook is a single-volume indication of the present state of the logic of argument and inference at its conceptual and theoretical best. Future editions will periodically incorporate significant new developments.

The writings of Kierkegaard continue to be a fertile source for con­ temporary philosophical thought. Perhaps the most interesting of his works to a philosopher is the Concluding Unscientific Postscript to the Philosophical Fragments. The Fragments is a brief, algebraic piece in which the author attempts to put forward the central teachings of Christianity in philosophical terminology. The. work is addressed to a reader who has a philosophical bent and who may therefore be tempted to relate to Christianity via such questions as: Can the truth of Christian­ ity be established? The analysis of the Fragments establishes that this way of relating to Christianity is misguided, since Christianity and phil­ osophy are categorically different. Having done this, the author turns his attention in the Postscript to the question of how an individual human being can properly establish a relationship to Christianity. In order to become a Christian, one must first of all exist. "Nothing more than thatP' one may be tempted to think. Yet at the very core of the Postscript is the notion that to exist as an individual human being is difficult. The author goes so far as to claim that men have forgotten what it means to exist.
