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

 relations of religion and science, and determines the legitimate scnpc 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 orders 

 of phenoncma, and thus constitute the foundation of all philosophy. Tho
