Thomas S. Kuhn's classic book is now available with a new index.

Several of these essays have been printed whole in journals; others are in varying degrees new. Two main themes run through them. One is the problem of meaning, particularly as involved in the notion of an analytic statement. The other is the notion of ontological, commitment, particularly as involved in the problem of universals.

The Spirit of the Soil challenges environmentalists to think more deeply and creatively about agriculture. Paul B. Thompson identifies four `worldviews' which tackle agricultural ethics according to different philosophical priorities; productionism, stewardship, economics and holism. He examines current issues such as the use of pesticides and biotechnology from these ethical perspectives. This book achieves an open-ended account of sustainability designed to minimise hubris and help us to recapture the spirit of the soil.
