The primary purpose of this book is to examine the logical features common to all the sciences. Each science proceeds by inventing general principles from which are deduced the consequences to be tested by observation and experiment; the author shows how the implications of this process explain some of its more baffling features and resolves many of the difficulties that philosophers have found in them. His exposition is by way of detailed examples.
