With examples ranging from timbering and fishing to automobility and meat production, Princen shows that sufficiency is perfectly sensible and yet absolutely contrary to modern society's dominant principle, efficiency. He argues that seeking enough when more is possible is both intuitive and rational - personally, organisationally and ecologically rational. And under global ecological constraint, it is ethical. Over the long term, an economy - indeed a society--cannot operate as if there's never enough and never too much.

What if modern society put a priority on the material security of its citizens and the ecological integrity of its resource base? What if it took ecological constraint as a given, not a hindrance but a source of long-term economic security? How would it organize itself, structure its industry, shape its consumption? Across time and across cultures, people actually have adapted to ecological constraint. They have changed behavior; they have built institutions. And they have developed norms and principles for their time. Today's environmental challenges—at once global, technological, and commercial—require new behaviors, new institutions, and new principles. In this highly original work, Thomas Princen builds one such principle: sufficiency. Sufficiency is not about denial, not about sacrifice or doing without. Rather, when resource depletion and overconsumption are real, sufficiency is about doing well. It is about good work and good governance; it is about goods that are good only to a point. With examples ranging from timbering and fishing to automobility and meat production, Princen shows that sufficiency is perfectly sensible and yet absolutely contrary to modern society's dominant principle, efficiency. He argues that seeking enough when more is possible is both intuitive and rational—personally, organizationally and ecologically rational. And under global ecological constraint, it is ethical. Over the long term, an economy—indeed a society—cannot operate as if there's never enough and never too much.

How to imagine and then realize an ecological order based on living within our biophysical means. We are living beyond our means, running up debts both economic and ecological, consuming the planet's resources at rates not remotely sustainable. But it's hard to imagine a different way. How can we live without cheap goods and easy credit? How can we consume without consuming the systems that support life? How can we live well and live within our means? In Treading Softly, Thomas Princen helps us imagine an alternative. We need, he says, a new normal, an ecological order that is actually economical with resources, that embraces limits, that sees sustainable living not as a “lifestyle” but as a long-term connection to fresh, free-flowing water, fertile soil, and healthy food. The goal would be to live well by living well within the capacities of our resources. Princen doesn't offer a quick fix—there's no list of easy ways to save the planet to hang on the refrigerator. He gives us instead a positive, realistic sense of the possible, with an abundance of examples, concepts, and tools for imagining, then realizing, how to live within our biophysical means.

Essays that offer ecological, social, and political perspectives on the problem of overconsumption.

The Principle of Sufficient Reason (PSR) says that all contingent facts must have explanation. In this 2006 volume, which was the first on the topic in the English language in nearly half a century, Alexander Pruss examines the substantive philosophical issues raised by the Principle Reason. Discussing various forms of the PSR and selected historical episodes, from Parmenides, Leibnez, and Hume, Pruss defends the claim that every true contingent proposition must have an explanation against major objections, including Hume's imaginability argument and Peter van Inwagen's argument that the PSR entails modal fatalism. Pruss also provides a number of positive arguments for the PSR, based on considerations as different as the metaphysics of existence, counterfactuals and modality, negative explanations, and the everyday applicability of the PSR. Moreover, Pruss shows how the PSR would advance the discussion in a number of disparate fields, including meta-ethics and the philosophy of mathematics.

"Growth" is the only political, economic and social goal recognized today. But it brings us up against the ecological limits of the planet - and against the increasingly widespread recognition of the fact that material wealth alone cannot make us happy. For this reason, ever growing numbers of people are seeking and discovering alternative and sustainable ways of living. This is to be welcomed, but it is not enough. We need a politics of sufficiency that will make it easier to live with fewer resources but with stronger relationships. This book outlines the political framework and policy guidelines that will enable us to reduce the speed, complexity, clutter and commercialization currently blighting our lives. And it demonstrates what that would mean in practice for where we live, how we get around, and how we eat, work and learn.
