These phenomenological studies on the philosophy of the image review contemporary image theory while defending the fundamental insight that images alone make the artificial presence of things possible.

In this book I address a dichotomy that is as central as any in ontology - that between ordinary objects or substances and the various attributes (Le. , properties, kinds, and relations) we associate with them. My aim is to arrive at the correct philosophical account of each member of the dichotomy. What I shall argue is that the various attempts to understand substances or attri butes in reductive terms fail. Talk about attributes, I shall try to show, is just that - talk about attributes; and, likewise, talk about substances is just tha- talk about substances. The result is what many will find a strange combina tion of views - a Platonistic theory of attributes, where attributes are univer sals or multiply exemplifiable entities whose existence is independent of "the world of flux", and an Aristotelian theory of substance, where substances are basic unities not reducible to metaphysically more fundamental kinds of things. Part One is concerned with the ontology of attributes. After distinguishing three different patterns of metaphysical thinking about attributes, I examine, in turn, the phenomena of predication, resemblance, and higher order quanti fication. I argue that none of these phenomena by itself is sufficient to establish the inescapability of a Platonistic interpretation of attributes. Then, I discuss the phenomenon of abstract reference as it is exhibited in the use of abstract singular terms.

The Ideal of Rationality presents an evaluation of all the main varieties of rationalism, in clear and jargon-free language. Different notions of rationality - such as means-end, conception, hedonism, and the evil-avoidance view - are examined and rejected, in favor of the theory that to act rationally is to 'act for the best', a theory Nathanson characterizes as "critical pluralism". Among present-day thinkers whose ideas are scrutinized are Richard Brandt, Bernard Gert, Gilbert Harman, John Kekes, Robert Nozick, Karl Popper, and John Rawls.

This book, combining integratively-revised previously-published papers with entirely new chapters, challenges and treats some major problems in Kant’s philosophy not by means of new interpretations but by suggesting some variations on Kantian themes. Such variations are, in fact, reconstructions made according to Kantian ideas and principles and yet cannot be extracted as such directly from his writings. The book also analyses Kant's philosophy from a new metaphysical angle, based on the original metaphysics of the author, called panenmentalism. It reconstructs some missing links in Kant's philosophy, such as the idea of teleological time, which is vital for Kant's moral theory. Although these variations cannot be found literally in Kant’s works, they can be legitimately explicated, developed, and implied from them. Such is the case because these variations are strictly compatible with the details of the texts and the texts as wholes, and because they are systematically integrated. Their coherence supports their validation. The target audiences are graduate and PhD students as well as specialist researchers of Kant's philosophy.

Sixty years after its first edition, there is an increasing consensus among scholars that the work posthumously published as Philosophical Investigations represents something that is far from a complete picture of Wittgenstein’s second book project. G.H. von Wright’s seminal research on the Nachlass was an important contribution in this direction, showing that the Wittgenstein papers can reveal much more than the source of specific remarks. This book specifically explores Wittgenstein’s Philosophical Investigations from the different angles of its originary conceptions, including the mathematical texts, shedding new light on fundamental issues in twentieth century and contemporary philosophy. Leading authorities in the field focus on newly published or hitherto unpublished sources for the interpretation of Wittgenstein’s later work and a Wittgenstein typescript, translated for the first time into English, is included as an appendix.
