Explains how new discoveries in anthropology might help politicians solve foreign policy matters.

First published in 1931 and originally delivered as the Deems Lectures at New York University in 1929, this book examines what scientific discoveries in many different branches of science reveal, and the implications of such discoveries for philosophy. Esteemed philosopher F. S. C. Northrop surveys a variety of advances, including relativity and quantum mechanics, and how they correlate to his epistemological theory of concepts. This book will be of value to anyone with an interest in the history of science and (...) the connection between science and philosophy. (shrink)

The concept of causality as it appears in a specific scientific theory involves two factors: the relation of necessary connection between the states of a system at different times, and the definition of state at a given time.

A striking characteristic of contemporary science is its emphasis upon probability. This is especially notable in quantum mechanics.There is a respect in which probability is the same for all scientific theories. Verifiability requires that any theory predict certain numbers which can be compared with the numbers gained by actual operations of measuring. In actual practice these numbers, which we shall term theoretical measurables and operative measurables respectively, never correspond. It becomes necessary, therefore, for the scientist to specify when the deviation (...) between them is such that verification occurs. These specifications are defined by the theory of errors in which the concept of probability has an essential place and a specific meaning. But the theory of errors is the same for all applications; hence, probability as defined by the theory of errors is the same for all scientific theories. (shrink)
