The author of the following work, Mr. Herbert Spencer, of England, has entered upon the publication of a new philosophical system, so original and comprehensive as to deserve the attention of all earnest inquirers. He proposes nothing less than to unfold such a complete philosophy of Nature, physical, organic, mental and social, as Science has now for the first time made possible, and which, if successfully executed, will constitute a momentous step in the progress of thought.
His system is designed to embrace five works; each a distinct treatise, but all closely connected in plan, and treating of the following subjects in the order presented: 1st, First Principles; 2d, Principles of Biology; 3d, Principles of Psychology; 4th, Principles of Sociology; 5th, Principles of Morality. The opening work of the series— First Principles —though somewhat of an introductory character, is an independent and completed argument. It consists of two parts: first, The Unknowable, and second, The Laws of the Knowable. Unattractive as these titles may seem, they indicate a discussion of great originality and transcendent interest.
