Bøger af Alvin (Professor of Philosophy Plantinga

Collecting the articles on the metaphysics of modality, this book chronicles Plantinga's thought from the late 1960's. It covers fundamental issues in metaphysics: what is the nature of abstract objects like possible worlds, properties, propositions, and such phenomena? Are there possible but non-actual objects?

Describes the notion of warrant as that which distinguishes knowledge from true belief. This volume examines warrant's role in theistic belief, tackling the questions of whether it is rational, reasonable, justifiable, and warranted to accept Christian belief and whether there is something epistemically unacceptable in doing so.

The aim of this study is to explore and defend the notion of modality "de re", the idea that objects have both essential and accidental properties. The argument is developed by means of the notion of possible worlds and ranges over such problems as the nature of essence and the problem of evil.
