Abstract
This is the first volume in the Vienna Circle collection. The editorial committee plans to publish a series of about thirty volumes between 1973 and 1980. This gigantic task should render immense service to both historians and contemporary philosophers. The basic aim is to present in English anthologies of "the most important work of single members, which should contain besides a detailed essay on the man a complete bibliography of his work." The present large anthology of the writings of Neurath presents a valuable collection of memories, in lieu of a biographical essay, revealing Neurath’s manysided interests and activities. Of more strictly philosophical interest are the short essays that deal with the history of optics, the problem of pleasure maximum, the scientific conception of the world; and a long selection from the book Empirical Sociology: The Scientific Content of History and Political Economy.
