  1. How Harmful Are the Average American's Greenhouse Gas Emissions?John Nolt - 2011 - Ethics, Policy and Environment 14 (1):3-10.
    It has sometimes been claimed (usually without evidence) that the harm caused by an individual's participation in a greenhouse-gas-intensive economy is negligible. Using data from several contemporary sources, this paper attempts to estimate the harm done by an average American. This estimate is crude, and further refinements are surely needed. But the upshot is that the average American is responsible, through his/her greenhouse gas emissions, for the suffering and/or deaths of one or two future people.

    Casualties as a Moral Measure of Climate Change.John Nolt - 2015 - Climatic Change 130 (3):347–358.
    Climate change will cause large numbers of casualties, perhaps extending over thousands of years. Casualties have a clear moral significance that economic and other technical measures of harm tend to mask. They are, moreover, universally understood, whereas other measures of harm are not. Therefore, the harms of climate change should regularly be expressed in terms of casualties by such agencies such as IPCC’s Working Group III, in addition to whatever other measures are used. Casualty estimates should, furthermore, be used to (...)

    Hope, Self-Transcendence and Environmental Ethics.John Nolt - 2010 - Inquiry: An Interdisciplinary Journal of Philosophy 53 (2):162 – 182.
    Environmental ethicists often hold that organisms, species, ecosystems, and the like have goods of their own. But, even given that such goods exist, whether we ought to value them is controversial. Hence an environmental philosophy needs, in addition to an account of what sorts of values there are, an explanation what, how and why we morally ought to value—that is, an account of moral valuing. This paper presents one such an account. Specifically, I aim to show that unless there are (...)

    The Move From Good to Ought in Environmental Ethics.John Nolt - 2006 - Environmental Ethics 28 (4):355-374.
    The move from good to ought, a premise form found in many justifications of environmental ethics, is itself in need of justification. Of the potential moves from good to ought surveyed, some have considerable promise and others less or none. Those without much promise include extrapolations of obligations based on human goods to nonsentient natural entities, appeals to educated judgment, precautionary arguments, humanistic consequentialist arguments, and justifications that assert that our obligations to natural entities are neither directly to those entities (...)

    Are There Infinite Welfare Differences Among Living Things?John Nolt - 2017 - Environmental Values 26 (1):73-89.
    Suppose, as biocentrists do, that even microorganisms have a good of their own - that is, some objective form of welfare. Still, human welfare is vastly greater and more valuable. If it were infinitely greater, individualistic biocentrism would be pointless. But consideration of the facts of evolutionary history and of the conceptual relations between infinity and incommensurability reveals that there are no infinite welfare differences among living things. It follows, in particular, that there is some very large number of bacteria (...)

    Environmental Ethics for the Long Term: An Introduction.John Nolt - 2014 - Routledge.
    Broad in scope, this introduction to environmental ethics considers both contemporary issues and the extent of humanity’s responsibility for distant future life. John Nolt, a logician and environmental ethicist, interweaves contemporary science, logical analysis, and ethical theory into the story of the expansion of ethics beyond the human species and into the far future. Informed by contemporary environmental science, the book deduces concrete policy recommendations from carefully justified ethical principles and ends with speculations concerning the deepest problems of environmental ethics.

    The Move From Is to Good in Environmental Ethics.John Nolt - 2009 - Environmental Ethics 31 (2):135-154.
    Moves from is to good—that is, principles that link fact to value—are fundamental to environmental ethics. The upshot is fourfold: (1) for nonanthropogenic goods, only those moves from is to good are defensible which conceive goodness as goodness for biotic entities; (2) goodness for nonsentient biotic entities is contribution to their autopoietic functioning; (3) biotic entities also function “exopoietically” to benefit related entities, and these exopoietic benefits are on average greater than their own goods; and (4) the most general is-to-good (...)

  14. Truth as an Epistemic Ideal.John Nolt - 2008 - Journal of Philosophical Logic 37 (3):203 - 237.
    Several philosophers—including C. S. Peirce, William James, Hilary Putnam and Crispin Wright—have proposed various versions of the notion that truth is an epistemic ideal. More specifically, they have held that a proposition is true if and only if it can be fixedly warranted by human inquirers, given certain ideal epistemic conditions. This paper offers a general critique of that idea, modeling conceptions of ideality and fixed warrant within the semantics that Kripke developed for intuitionistic logic. It is shown that each (...)

    Why Nietzsche Embraced Eternal Recurrence.John Nolt - 2008 - History of European Ideas 34 (3):310-323.
    Nietzsche's embrace of the idea of eternal recurrence has long puzzled readers, both because the idea is inherently implausible and because it seems inconsistent with other aspects of his philosophy. This paper offers a novel account of Nietzsche's motives for that embrace—namely that Nietzsche found in eternal recurrence the only possible way to reconcile three potent and apparently conflicting convictions: there are no Hinterwelten , the great love all things just as they are , and all joy wills eternity. The (...)

    Reference and Perspective in Intuitionistic Logics.John Nolt - 2006 - Journal of Logic, Language and Information 16 (1):91-115.
    What an intuitionist may refer to with respect to a given epistemic state depends not only on that epistemic state itself but on whether it is viewed concurrently from within, in the hindsight of some later state, or ideally from a standpoint “beyond” all epistemic states (though the latter perspective is no longer strictly intuitionistic). Each of these three perspectives has a different—and, in the last two cases, a novel—logic and semantics. This paper explains these logics and their semantics and (...)

    Anthropocentrism and Egoism.John Nolt - 2013 - Environmental Values 22 (4):441-459.
    Concern with ethical anthropocentrism has largely been confined to debates in animal and environmental ethics. Philosophers generally have shown little interest in it. Ethical egoism, by contrast, though usually rejected, has sparked wide philosophical interest. This is surprising, for the two are akin; anthropocentrism is egoism writ large - the egoism of the human species. This paper explains the kinship by articulating this analogy, shows that the analogy provides for each argument for or against ethical egoism an analogous argument for (...)

  19. An Argument for Metaphysical Realism.John Nolt - 2004 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 35 (1):71-90.
    This paper presents an argument for metaphysical realism, understood as the claim that the world has structure that would exist even if our cognitive activities never did. The argument is based on the existence of a structured world at a time when it was still possible that we would never evolve. But the interpretation of its premises introduces subtleties: whether, for example, these premises are to be understood as assertions about the world or about our evidence, internally or externally, via (...)

    Incomparable Values: Analysis, Axiomatics and Applications.John Nolt - 2021 - Routledge.
    People tend to rank values of all kinds linearly from good to bad, but there is little reason to think that this is reasonable or correct. This book argues, to the contrary, that values are often partially ordered and hence frequently incomparable. Proceeding logically from a small set of axioms, John Nolt examines the great variety of partially ordered value structures, exposing fallacies that arise from overlooking them. He reveals various ways in which incomparability is obscured: using linear indices to (...)

    An outline of the material covered in courses on Formal and Informal Logic. The outline includes chapters on mathematical approaches to logic as well as on fallacies, deduction and induction, probability, and other major topics. Logic is traditionally taught by means of problem solving exercises, so the subject is well suited to a Schaum's Outline approach.

    Moral life often presents us with trade-offs between the sufferings of some individuals and the sufferings of others. Researchers may need to consider, for example, whether the suffering imposed on animals by a certain line of medical experimentation justifies the relief that the resulting discoveries may bring to others. Often in such cases, the suffering of some individuals is incomparable with—that is neither greater than nor less than nor equal to—the suffering of others. While this complicates moral decision-making across species, (...)
