In the first part of this work Mr. Spencer defines the province, limits, and 

 relations of religion and science, and determines the legitimate scope of 

 philosophy. 



In part second he unfolds those fundamental principles which have been 

 arrived at within the sphere of the knowable ; which are true of all order* 

 of phenonema, and thus constitute the foundation of all philosophy. The 

 law of Evolution, Mr. Spencer maintains to be universal, and he has here 

 worked it out as the basis of his system. 



These First Principles are the foundation of a system of Philosophy 

 bolder, more elaborate, and comprehensive perhaps, than any other which 

 oat been hitherto designed in England. British Quarterly Review.

In the works of Herbert Spencer we have the rudiments of a positiye 

 Theology, and an immense step toward the perfection of the science of Psy 

 chology. Christian Examiner. 



If we mistake not, HI spite of the very negative character of his own re 

 mits, he has foreshadowed some strong arguments for tlie doctrine of a po- 

 tie Christian Theology. New Englander.
