This is a work destined, as we can easily foresee, to produce great good. Its leading design, as its title implies, and as is stated indeed by the author in his preface, is to elucidate the influence of intellect and passion upon the health and endurance of the human organization; an influence which has been but imperfectly understood and appreciated in its character and importance, by mankind at large. The volume under notice is divided into two parts. Under the first are considered the intellectual operations in respect to their influence on the general functions of the body; under the second is embraced a view of the moral feelings or passions, in the relation which they also sustain to our physical nature. Of these a concise definition is offered, with such classification as is necessary to the leading design of the work. Their effects upon the different functions of the animal economy are next noticed; and a description is given of a few of the most important passions belonging to each of the three great classes; namely, pleasurable, painful and mixed, into which they are separated; their physical phenomena and individual influence on the well-being of the human mechanism being closely examined. A forcible exposition is also given of the evil consequences resulting from an ill-regulated imagination (acting through the instrumentality of the passions, morbidly excited by its licentious operation,) to the firmness of the nervous system, and the integrity of the general health. The volume is not addressed to any particular class of readers, and being free from technical expressions, is rendered plain and comprehensive to all. We commend this volume of Mr. SWEETSER cordially to our readers, firmly impressed with the belief that the principles which it advances may be rendered subservient both to the physical and moral welfare of our countrymen.
