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

 relations of religion and eciencc, and determines the legitimate bopo of 

 philosophy. 



In part second he unfolds those fimdamental principles which have been 

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

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

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

 worked it out as the basis of his system. 



These First Principles are the foundation of a system of Philosopfaj 

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

 oat been hitherto designed in England. — British Quario'li/ Review. 



A work lofty in aim and remarkable in executioa — Coi'rJiill Mayozint.

 Tiipology, and an inmiense step toward the perfection of the science of Y^y 

 Ci\ ology. — Christian Exam in er. 



If we miiitake not, in spite of the very negative character of his owr. ro 

 tnlts, be has foreshadowed some strong arguments for the doctrine of a poai- 

 lite Christian Theology. — New Enylandtr.
