work. ... I never in my life read so lucid an expositor (and 

 therefore thinker) as you are; and I think that I understand 

 nearly the whole, though perhaps less clearly about cosmic 

 theism and causation than other parts. It is hopeless to at- 

 tempt out of so much to specify what has interested me most, 

 and probably you would not care to hear. It pleased me to 

 find that here and there I had arrived, from my own crude 

 thoughts, at some of the same conclusions with you, though I 

 could seldom or never have given my reasons for such con 

 elusions." CHARLES DARWIN.

If ever there was a spirit thoroughly invigorated by the 

 "joy of right understanding " it is that of the author of these

 power, and faculty of clear statement, that appear in all these 

 papers, Mr. Fiske adds a just independence of thought that 

 conciliates respectful consideration of his views, even when

Among our thoughtful essayists there are none more bril- 

 liant than Mr. John Fiske. His pure style suits his clear
