Excerpt from Theory and Problems of Social Psychology<br><br>This book is designed for the teacher and the student who are primarily interested in the science of psychology as a systematic, interpretive account of human behavior and who are interested in applying the science of psy chology to current social issues. In attempting to meet these requirements the authors have not found it necessary to keep two sets of readers in mind or to treat the subject matter of this book from two points of view. The basic guiding principle has been that a theoretically sound social psychology is also a practically valid and immediately useful social psychology. Neither the pure scientist nor the man of action can neglect public opinion survey data or experiments on perceptual organization without running the risk of making his theory truncated and narrow or his program of action superficial and ineffective.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
