Book Description
Excerpt from The Biological Problem of to-Day: Preformation or Epigenesis? The Basis of a Theory of Organic Development Shortly after the appearance of Dr. Oscar Hert wig's treatise Preformation oder Epigenese I published in Natural Science (1894) a detailed abstract of it. But the momentous issues involved in the problem of heredity, and the great interest excited by Dr. Weismann's theories, make it de sirable that a full translation should appear. By the kindness of Dr. Hertwig and his German pub lisher, this is now possible. I have prefixed an introduction, written for those who are interested in the general problem, but who have little acquaint ance with the technical matters on which the argument turns. In the actual translation I have tried no more than to give a faithful rendering of the German. After no little perplexity, I have rendered the German word Anlagc as rudiment.' It is true, a double meaning has been grafted upon the English word, and it is widely employed to mean an undeveloped structure, without discrimination between incipient and vestigial character. I use it in the etymological sense, as an incipient structure. For the difficult words, Efrbglcz'ch and Erbunglcfich, a succession of new terms have been suggested. Here I use for the first term the word doubling, ' for the second differentiating.' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Is contemporary continental philosophy making a break with Kant? The structures of knowledge, taken for granted since Kant's Critique of Pure Reason, are now being called into question: the finitude of the subject, the phenomenal given, a priori synthesis. Relinquish the transcendental: such is the imperative of postcritical thinking in the 21st century. Questions that we no longer thought it possible to ask now reemerge with renewed vigor: can Kant really maintain the difference between a priori and innate? Can he deduce, rather than impose, the categories, or justify the necessity of nature? Recent research into brain development aggravates these suspicions, which measure transcendental idealism against the thesis of a biological origin for cognitive processes. In her important new book Catherine Malabou lays out Kant's response to his posterity. True to its subject, the book evolves as an epigenesis – the differentiated growth of the embryo – for, as those who know how to read critical philosophy affirm, this is the very life of the transcendental and contains the promise of its transformation.

Book Description
The book is divided into 26 chapters and an index. Each chapter deals with a different scientific classification of animal life. The author is keen to point out that much of the knowledge scientists have now has been gleaned through the use of microscopes that can see what the human eye cannot, unaided.

Book Description
This book and the symposium on which it was based were designed to cross the boundaries of subdiscipline and theoretical orientation to address four critical issues in understanding development: explanation of change and development; the nature and process of change; forms of variability in performance; and the promotion of change through application. The chapters suggest that change and development in target systems from cells to selves, may not be explainable, assessable, or promotable without careful reference to the context (social and otherwise) of the system, and that the process of change and development may involve variability of the system in addition to periods of stability. Together the chapters harken back to the spirit of the grand theory. Instead of proposing a grand theory, they provide an excellent foundation for considering the importance of an individual's (or particular group's) context and variability, and discussions to facilitate thinking about what still needs to be worked out.
