"A remarkable book that influenced the scientific thought of an entire generation."--Dictionary of Scientific Biography
A major statement of the language, method, and concepts of the physical sciences, this 1892 volume traces not only the history of experimental investigation but also the efforts of philosophic minds to state and organize their findings intelligently. A classic in the philosophy of science, its author is the founder of modern statistics. Karl Pearson was among the most influential university teachers of his era, and he possessed a remarkable ability to captivate both students and casual listeners. In The Grammar of Science, his most widely read book, he introduced the concept of a general methodology underlying all science, and thus made one of the great contributions to modern thought. 1957 ed.
