Meaning (significance) and nature are this book's principal topics. They seem an odd couple, like raisins and numbers, though they elide when meanings of a global sort-ideologies and religions, for example-promote ontologies that subordinate nature. Setting one against the other makes reality contentious. It signifies workmates and a coal face to miners, gluons to physicists, prayer and redemption to priests. Are there many realities, or many perspectives on one? The answer I prefer is the comprehensive naturalism anticipated by Aristotle and Spinoza: "natura naturans, natura naturata." Nature naturing is an array of mutually conditioning material processes in spacetime. Each structure or event-storm clouds forming, nature natured-is self-differentiating, self-stabilizing, and sometimes self-disassembling; each alters or transforms a pre-existing state of affairs. This surmise anticipated discoveries and analyses to which neither thinker had access, though physics and biology confirm their hypothesis beyond reasonable doubt. Hence the question this book considers: Is reality divided:nature vrs. lived experience? Or is experience, with all its meanings and values, the complex expression of natural processes?

Traditional moral theory usually has either of two emphases: virtuous moral character or principles for distributing duties and goods. Zone Morality introduces a third focus: families and businesses are systems created by the causal reciprocities of their members. These relations embody the duties and permissions of a system's moral code. Core systems satisfy basic interests and needs; we move easily among them hardly noticing that moral demands vary from system to system. Moral conflicts arise because of discord within or among systems but also because morality has three competing sites: self-assertive, self-regarding people; the moral codes of systems; and regulative principles that enhance social cohesion. Each wants authority to control the other two. Their struggles make governance fragile. A strong church or authoritarian government reduces conflict by imposing its rules, but democracy resists that solution. Procedural democracy is a default position. Its laws and equitable procedures defend people or systems having diverse interests when society fails to create a public that would govern for the common interest.

Cities are conspicuous among settlements because of their bulk and pace: Venice, Paris, or New York. Each is distinctive, but all share a social structure that mixes systems (families, businesses, and schools), their members, and a public regulator. Cities alter this structure in ways specific to themselves: orchestras play music too elaborate for a quartet; city densities promote collaborations unachievable in simpler towns. Cities, Real and Ideal avers with von Bertalanffy, Parsons, Simmel, and Wirth that a theory of social structure is empirically testable and confirmed. It proposes a version of social justice appropriate to this structure, thereby updating Marx's claim that justice is realizable without the intervention of factors additional to society's material conditions.

Philosophic attention shifted after Hegel from Kant s emphasis on sensibility to criticism and analyses of the fine arts. The arts themselves seemed as ample as nature; a disciplined science could devote as much energy to one as the other. But then the arts began to splinter because of new technologies: photography displaced figurative painting; hearing recorded music reduced the interest in learning to play it. The firm interiority that Hegel assumed was undermined by the speed, mechanization, and distractions of modern life. We inherit two problems: restore quality and conviction in the arts; cultivate the interiority the sensibility that is a condition for judgment in every domain. What is sensibility s role in experiences of every sort, but especially those provoked when art is made and enjoyed?"

Lost Souls examines the origins and consequences of the philosophic idea that mind and body are distinct. The author traces mind-body dualism from Plato, Plotinus, Augustine, and Proclus through Descartes and Kant to Nietzsche, Heidegger, Carnap, and Quine. Mind's separation from body has dominated philosophic thinking for millennia, yet most mental activities are now explained in physical terms. What are the implications if mind is material and mortal? Considering both philosophic and scientific ideas about mind, David Weissman explores our options. Rejecting the claim that the character and existence of other things are an effect of the ways we think about or perceive them, he reexamines such topics as meaning and truth, human significance, self, and society. He argues that philosophers have the rare opportunity to renew inquiry by invoking the questions that once directed them: What are we? What is our place in the world? What concerns are appropriate to being here?

Moral and social philosophers often assume that humans beings are and ought to be autonomous. This tradition of individualism, or atomism, underlies many of our assumptions about ethics and law; it provides a legitimating framework for liberal democracy and free market capitalism. In this powerful book, David Weissman argues against atomistic ontologies, affirming instead that all of reality is social. Every particular is a system created by the reciprocal causal relations of its parts, he explains. Weissman formulates an original metaphysics of nature that remains true to what is known through the empirical sciences, and he applies his hypothesis to a range of topics in psychology, morals, sociology, and politics. The author contends that systems are sometimes mutually independent, but many systems-human ones especially-are joined in higher order systems, such as families, friendships, businesses, and states, that are overlapping or nested. Weissman tests this schematic claim with empirical examples in chapters on persons, sociality, and value. He also considers how the scheme applies to particular issues related to deliberation, free speech, conflict, and ecology.

Is something true because we believe it to be so or because it is true? How can a culturally bound community achieve scientific knowledge when values, attitudes, and desires shape its beliefs? In this book an eminent philosopher considers various schools of thought on the nature of truth. David Weissman argues that truth exists in the correspondence between statement and fact: what can be said about our world can be measured against a reality that has a character and existence independent of any property we ascribe to it. Weissman begins by evaluating the transcendental paradigm of Kant that has exercised enormous influence in the development of Western thought over the past two hundred years. He develops his critique of the Kantian model (which states that value judgments underlie the perception or construction of truth), asserting that it is seriously flawed because it renders a determination of truth impossible. Weissman examines various value-driven perspectives on truth developed by such philosophers as Foucault, Derrida, and Rorty, who feel that truth is only the set of affirmations, principles, and procedures sanctioned by power and value. However, says Weissman, truth is the required adjunct to desire. Knowing who we are, where we have been, and the consequences of what we have done is the essential preparation for choosing what to do next. We must respect the integrity of a world we have not made and find our way within it with the help of attitudes and desires that have been informed by truth.
