Philosophical Essays is a pivotal volume in the collected works of Hans Jonas (1903-1993), one of most important German-American philosophers of the last half of the 20th century. Of the four books published in English during his lifetime, it is the only one to include contributions from his three primary areas of achievement: philosophical reflection on gnosticism, on biology, and on technology - hence the subtitle, "From Ancient Creed to Technological Man." The three sections of the book are, however, given in reverse order with essays on "Science, Technology, and Ethics" preceding papers on "Organism, Mind, and History" and "Religious Thought of the First Christian Centuries." The temporally ultimate project is that which Jonas sees as having philosophical priority. This collection of 18 essays originally published between 1965 and 1974 - that is, after completion of The Phenomenon of Life (1966) but before The Imperative of Responsibility (1984) - manifests the most intensive integration of Jonas's three projects. As such, this volume provides special witness to the inherent unity of what might otherwise be seen as more episodic work. In the Introduction Jonas himself argues for both a biographical and a philosophical unity, the latter of which is emphasized in a new foreword by Carl Mitcham of the European Graduate School.

This volume, first published in English in 1987 makes available an important part of Weil’s early writings. Although primarily known as a religious thinker, she devoted enormous energy in her formative years to her work as a political activist and as a philosopher/teacher. This book reveals these other sides of Weil and demonstrates the lines of continuity underlying her whole thought. Written between 1929 and 1941 the book covers a crucial and transitional period in Weil’s life. Taken together they represent invaluable primary source material on the evolution of Weil’s life and on her chosen method of abstracting elements from her personal experience and transmuting that experience into considered thought. Even when highly theoretical, her writing was always concerned with the application of her intelligence to concrete problems of human existence.

Whereas science, technology, and medicine have all called forth dedicated philosophical investigations, a fourth major contributor to the technoscientific world in which we all live - that is, engineering - has been accorded almost none of the philosophical attention it deserves. This volume thus offers a first characterisation of this important new field, by some of the primary philosophers and ethicists interested in engineering and leading engineers interested in philosophical reflections. The volume deals with such questions as: What is engineering? In what respect does engineering differ from science? What ethical problems does engineering raise? By what ethical principles are engineers guided? How do engineers themselves conceive of their profession? What do they see as the main philosophical challenges confronting them in the 21st century? The authors respond to these and other questions from philosophical and engineering view points and so illustrate how together they can meet the challenges and realize the opportunities present in the necessary encounters between philosophy and engineering - encounters that are ever more important in an increasingly engineered world and its problematic futures.
