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.
