The basic question of ontology is “What exists?”. The basic question of metaontology is: are there objective answers to the basic question of ontology? Here ontological realists say yes, and ontological anti-realists say no. (Compare: The basic question of ethics is “What is right?”. The basic question of metaethics is: are there objective answers to the basic question of ethics? Here moral realists say yes, and moral anti-realists say no.) For example, the ontologist may ask: Do numbers exist? The Platonist (...) says yes, and the nominalist says no. The metaontologist may ask: is there an objective fact of the matter about whether numbers exist? The ontological realist says yes, and the ontological anti-realist says no. Likewise, the ontologist may ask: Given two distinct entities, when does a mereological sum of those entities exist? The universalist says always, while the nihilist says never. The metaontologist may ask: is there an objective fact of the matter about whether the mereological sum of two distinct entities exists? The ontological realist says yes, and the ontological anti-realist says no. Ontological realism is often traced to Quine (1948), who held that we can determine what exists by seeing which entities are endorsed by our best scientific theory of the world. In recent years, the practice of ontology has often presupposed an ever-stronger ontological realism, and strong versions of ontological realism have received explicit statements by Fine (this volume), Sider (2001; this volume), van Inwagen (1998; this volume), and others.

This paper compares Kant's transcendental idealism with three main groups of contemporary anti-realism, associated with Wittgenstein, Putnam, and Dummett, respectively. The kind of anti-realism associated with Wittgenstein has it that there is no deep sense in which our concepts are answerable to reality. Associated with Putnam is the rejection of four main ideas: theory-independent reality, the idea of a uniquely true theory, a correspondence theory of truth, and bivalence. While there are superficial similarities between both views and Kant's, I find (...) more significant differences. Dummettian anti-realism, too, clearly differs from Kant's position: Kant believes in verification-transcendent reality, and transcendental idealism is not a theory of meaning or truth. However, I argue that part of the Dummettian position is extremely useful for understanding part of Kant's position - his idealism about the appearances of things. I argue that Kant's idealism about appearances can be expressed as the rejection of experience-transcendent reality with respect to appearances. (shrink)

When Timothy Sprigge's The Vindication of Absolute Idealism appeared in 1983 it ran very much against the grain of the dominant linguistic and analytic traditions of philosophy in Britain. The very title of this work was a challenge to those who believed that Absolute Idealism fell with the critiques of Bertrand Russell and G. E. Moore at the beginning of the 20th century. Sprigge, however, saw himself as providing an underrepresented position in the philosophical spectrum rather than as advocating an (...) abandoned view. For him, idealism did not fall at any determinate point in the history of philosophy. The truth of any philosophical thesis cannot depend on what happens to be currently fashionable, but rather must stand on the soundness of philosophical argument. To this end, The Vindication of Absolute Idealism is a bold statement of his conclusions, a synthesis of panpsychism and absolute idealism, which he contends is the most satisfactory solution to the question of the nature of consciousness and the mind-body problem. Sprigge's view of consciousness remains a challenge to mainstream physicalism and a viable option that addresses pressing contemporary concerns not only in metaphysics and philosophy of mind but also in environmental ethics and animal rights.
