As plant physiology increased steadily in the latter half of the 19th century, problems of absorption and transport of water and of mineral nutrients and problems of the passage of metabolites from one cell to another were investigated, especially in Germany. JUSTUS VON LIEBIG, who was born in Darmstadt in 1803, founded agricultural chemistry and developed the techniques of mineral nutrition in agricul ture during the 70 years of his life. The discovery of plasmolysis by NAGEL! (1851), the investigation of permeability problems of artificial membranes by TRAUBE (1867) and the classical work on osmosis by PFEFFER (1877) laid the foundations for our understanding of soluble substances and osmosis in cell growth and cell mechanisms. Since living membranes were responsible for controlling both water movement and the substances in solution, "permeability" became a major topic for investigation and speculation. The problems then discussed under that heading included passive permeation by diffusion, Donnan equilibrium adjustments, active transport processes and antagonism between ions. In that era, when organelle isolation by differential centrifugation was unknown and the electron microscope had not been invented, the number of cell membranes, their thickness and their composition, were matters for conjecture. The nature of cell surface membranes was deduced with remarkable accuracy from the reactions of cells to substances in solution. In 1895, OVERTON, in U. S. A. , published the hypothesis that membranes were probably lipid in nature because of the greater penetration by substances with higher fat solubility.

For the first time this book provides a comprehensive diagnostic for all different methods in psychotherapy. Because of the individual approaches and structures this could not be realized until know. Experts of seventeen schools-of-thought came together at a round table and drew up guidelines for the daily work of psychotherapists. The result is documented in this book, containing a summary of relevant standard questions; it also includes methodological commentaries for practical implementation. Despite the individual approach of the different types of psychotherapies, this psychotherapeutic diagnostic is applicable for all psychotherapists.

As the history of philosophy shows, it has been under permanent discussion at all times. Traditional discourse about - ality covers the full range from basic metaphysical foundations to operational approaches concerning human kinds of gathering and utilizing knowledge, broadly speaking epistemic approaches. However, no period in time has ex- rienced a number of moves changing and, particularly, restraining traditional concepts of reality that is comparable to the 20th century. Early in the 20th century, quite an in?uential move of such a kind was due to the so-called Copenhagen interpretation of quantum mechanics, laid out essentially by Bohr, Heisenberg, and Pauli in the mid 1920s. Bohr’s dictum, quoted by Petersen (1963, p.12), was that “it is wrong to think that the task of physics is to ?nd out how nature is. Physics concerns what we can say about nature.” Although this standpoint was not left unopposed – Einstein, Schr ̈ odinger, and others were convinced that it is the task of science to ?nd out about nature itself – epistemic, operational attitudes have set the fashion for many discussions in the philosophy of physics (and of science in general) until today.

The ability to reason ethically is an extraordinarily important aspect of professionalism in any field. Indeed, the greatest challenge in ethical professional practice involves resolving the conflict that arises when the professional is required to choose between two competing ethical principles. Ethical Reasoning in the Mental Health Professions explores how to develop the ability to reason ethically in difficult situations. Other books merely present ethical and legal issues one at a time, along with case examples involving "right" and "wrong" answers. In dramatic contrast, Ethical Reasoning in the Mental Health Professions provides you with the needed background in methods of ethical reasoning and introduces an innovative nine-step model of ethical decision-making for resolving ethical dilemmas. Ethical Reasoning in the Mental Health Profession discusses the ethical codes of both psychology and counseling. This interdisciplinary approach promotes a better understanding of the similarities and differences in the points of emphasis in the two codes, which, in turn, enriches your understanding of the range of ethical considerations relevant to the practice of the mental health professions.
