in terms of the known, of the infinite in terms of hu-

 the unreality he assigns to the foundations of science. 

 This appearance of reality is the base of Haeckel's

 liveableness, for insanity is death. The "borderland of 

 spirit," of which we hear so much of late — the land 

 where subjective and objective creations jostle each 

 other at will — is the borderland of death. The con- 

 tinued existence of animals and men is based on the 

 adequacy of their sensations and the veracity of their 

 actions. The existence of any creature is in general 

 proof of the sanity of its ancestry, or at least of the

 about him is not allowed to live in it. This fact in all 

 its bearings must stand as a proof that the universe is
