The Way out of Agnosticism 



Or, The Philosophy of Free lleligion. By Fkancis ELLix(iwooi) 



AititOT, Ph.D. Ciotli, $1.00. 

 This little book, giving the substance of a course of lectures in Harvard I'niversity 

 ii) 1fi8H, is a short, terse, and compact argument, drawn solely from science and i)hilos- 

 ophy, to prove that the essential constitution of the Universe is iiositively knowable 

 and known as at once an infinite Machine, an infinite Organism, and an infinite Person ; 

 and that this Scientific WOKLU-(Jo^cElTIO^" is the necessary foundation of Scien- 

 TM'IC ICthics. 



Ktldcal Reliijion. 



A volume of lectures S'ven, for the most ])art, l)cfore the Society for 



Ktliical Cultvirc, Cliica<;o. By Wm. ,M. Saltki;. ^1.50. 

 There is here, in glowing, suji^estive epitome, the essence of true human being and 

 doing. The New Ideal. Another ])roof that ideas as well as dollars are current in 

 A\nbT\c:x. Cermnn /leriew. The chai)ter on Darwinism in Ethics is a particularly 

 able dii-.cussion of that tojvic, and it is filled with high and noble conceptions of man's 

 responsibility to the law whicli says, Thou shalt do riglit or perish. 7 /le Jieacon.
