Solipsism is one of the philosophical thesis or ideas that has generally been regarded as highly implausible, or even crazy. The view that the world is “my world” in the sense that nothing exists independently of my mind, thought, and/or experience is, understandably, frowned up as a genuine philosophical position. For this reason, solipsism might be regarded as an example of a philosophical position that does not “matter” at all. It does not seem to play any role in our serious attempts to understand the world and ourselves. However, by arguing that solipsism does matter, after all, Why Solipsism Matters more generally demonstrates that philosophy, even when dealing with highly counterintuitive and “crazy” ideas, may matter in surprising, unexpected ways. It will be shown that the challenge of solipsism should make us rethink fundamental assumptions concerning subjectivity, objectivity, realism vs. idealism, relativism, as well as key topics such as ethical responsibility – that is, our ethical relations to other human beings – and death and mortality. Why Solipsism Matters is not only an historical review of the origins and development of the concept of solipsism and a exploration of some of its key philosophers (Kant and Wittgenstein to name but a few) but it develops an entirely new account of the idea. One which takes seriously the global, socially networked world in which we live in which the very real ramifications of solipsism - including narcissism - can be felt.

Solipsism indicates an epistemological position that denies the existence of ‘others’ by asserting that the ‘self’ is the only thing that can be known to exist. For sophist philosophers, the belief that “we can not know anything, and even if we do so, we cannot communicate it” is central to this theory. However, until now there has been little academic scholarship that has tried to provide answers to the pressing issues raised by solipsism. In Solipsist Ontology: Physical Things and Personal Perceptual Space, Ural aims to redefine solipsism by analyzing and elaborating on traditional philosophical problems, such as empiricism and rationalism, as well as discussing problems of language, communication, and meaning. Ural reveals where solipsism has been previously ignored, pseudo-problems have arisen that disguise the sources of the problems with prejudices that concern the philosophical problems in question. Notably, many current, as well as traditional problems of ontology, epistemology, and language are bound up in discourses of solipsism. Ural argues that discarding solipsism as a philosophical discourse hinders new interpretations of traditional philosophical thought. This book offers a fresh perspective to solipsism by defining it in relation to concepts such as ‘physical things,’ ‘personal perceptual space’ and ‘identity.’ Importantly, Ural proposes that an understanding of ‘identity’ is not necessary in order to redefine solipsism. By building a logical system that fashions communication and solipsism as interrelated, it is possible to reject ‘identity’ as a useless concept and thus overcome the classic solipsist dilemma of “we are not able to communicate.” This original piece of research is an important and timely contribution to the field of philosophy that will be of great interest to teachers, researchers, and students.

"The specter haunting modern philosophy is not the ghost in the machine: it is solipsism."

Rae Langton here draws together her ground-breaking and contentious work on pornography and objectification. She shows how women come to be objectified and she argues for the controversial feminist conclusions that pornography subordinates and silences women, and women have rights against pornography.

Much attention has been paid to Wittgenstein’s treatment of solipsism and to Cavell’s treatment of skepticism. But comparatively little has been made of the striking connections between the early Wittgenstein’s view on the truth of solipsism and Cavell’s view on the truth of skepticism, and how that relates to the claim that the later Wittgenstein sees privacy as a constant human possibility. This book offers close readings of representative writings by both authors and argues that an adequate understanding of solipsism and skepticism requires taking into account a set of underlying difficulties related to a disappointment with finitude which might ultimately lead to the threat of solipsism. That threat is further interpreted as a wish not to bear the burden of having to constantly negotiate and nurture the fragile connections with the world and others which are the conditions of possibility for finite beings to achieve meaning and community. By presenting Wittgenstein’s and Cavell’s responses in an order which reflects the chronology of their writings, the result is a cohesive articulation of some under-appreciated aspects of their philosophical methodologies which has the potential of reorienting our entire reading of their work.

This book examines skeptical problems originally raised by Descartes and Hume and currently discussed in philosophy of mind, philosophy of language, metaphysics, and epistemology. It answers the basic skeptical questions concerning the existence of what is now unperceived, the reality of what is perceived, and the existence of an external world. Johnstone shows how the recently proposed solutions to these skeptical problems— pragmatic, coherentist, linguistic, and new-Kantian — do not and cannot work, and how only a return to foundational investigation on the terrain of the radical skeptic is adequate to the task. His analyses make for a valuable summary of every significant argument brought against skepticism. In the course of his investigation, Johnstone probes a number of topical issues: knowledge, rationality, the nature of meaning, nonverbal thinking, the bodily nature of the thinking self, parasitism, the role of the tactile-kinesthetic body in feeling and belief, and the necessary role of free will in epistemology.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility.
