Nature From Within

A brilliant book. . . . No historian of nineteenth- and early twentieth-century German science and philosophy can afford to ignore it.

* British Journal for the History of Science *

A clear, comprehensive, and rigorous treatment of the philosophical basis for Fechner's thought, including, importantly, the way in which he was able to reconcile apparently divergent intellectual themes in his philosophical and scientific writing.

Almost mandatory reading as it provides many new historical insights that are quite significant for contemporary philosophy of science.

* Vienna Circle Institute Yearbook *

From Fechner to Peirce and Freud—Heidelberger explains the context and influence of Fechner's ideas on indeterminism, self-organization, psychophysics, and freedom. . . . A highly informative and comprehensive book about one of the most original and uncompromising thinkers of the nineteenth century.

Not very many exemplars of this genre get translated, and perhaps often justifiedly so. In Heidelberger's case there were excellent reasons for producing an English version. The impressive 66-page bibliography at the end of the volume is in itself a joy to study.

* Philosophy in Review *

This superb translation is revised and enlarged from the 1993 German edition, which was acclaimed as one of the finest and most useful studies of 19th-century thought. For the English version, the same accolades apply. . . . Nature from Within is mandatory reading for psychologists, philosophers, and historians of ideas. . . . Highly recommended.
