32 Prof. Ernst Haeckel. 



system becomes a duality which denies that the Ego is a 

 correlate of the known or knowable world. His philosophy, 

 therefore, leaves the backbone of the world of causal-se- 

 quence broken at the vital point where the objective and 

 subjective unite in Humanity, but not in any Unknowable. 

 The human head is thus fatally dissevered from its world- 

 body. That is to say, he assumes that everything is only a 

 symbol of reality; that every phenomenon is related to a 

 " noumenon " ; and that the consciousness of man is not a 

 correlate of nerve and world changes ; and so between the 

 world and man lies an unaccountable gulf, which is an open 

 gateway through which Eiske and Wallace and the clerical 

 and spiritual "mediums" have (doubtless contrary to his 

 intention) brought back the whole ghostly tribe of entities 

 and spirits, gods and devils, to torture and rob the human 

 race again. The trouble is, that Mr. Spencer, in assuming 

 an " infinite and eternal energy " back of " all things," an ab- 

 solutely unknowable, inscrutable, unhuman noumenon, has 

 lost his grip on the infinite and eternal causal concatenation 

 of things. He has run science ashore on the old sand and 

 fog bank of superstition. There is nothing to do but to 

 pull off, and to change our course under the true lights and 

 verifiable methods of the correlation of " all things." * 



Let us be thankful, then, that there is one complete evo- 

 lutionist who knows that there is " a causal sequence of phe- 

 nomena " from the farthest star up to and including the mind 

 of man ; and that phenomena are not metaphysical appear- 

 ances or " symbols," but facts, events, changes, processes, 

 realities ! This avowal of the universality of the law of 

 equivalence and correlation in the works of Prof. Haeckel 

 renders them epoch-making books in philosophy and reli- 

 gion as well as in science. According to that law, which 

 has no limit, no exception (not even of the human con- 

 sciousness or Ego), THE WORLD is ONE ; this doctrine is MO- 

 NISM. All of the world's changes are held together by this 

 one fundamental law of causal correlation, from our mind 

 that thinks (the true noumenon), ever on in boundless space 

 and time. Others had said the same thing partially, or in 

 whispers. Haeckel said it boldly, and with an evident de- 



* It may seem ungracious to refer thus to the " Prophecies " of Newton, the 

 "Papacy" of Comte, the "Spiritism" of Wallace, and the "Unknowable" of 

 Spencer and Fiske. But the errors of great men do great harm. Gratitude to 

 them for their pre-eminent services, and protection from the harm of their errors, 

 both require a fearless appeal to science, evolution, and their practical results. 

 Sufficient time has passed to show, in the opinion of the writer, that none of the 

 ideas above quoted can stand such an appeal.
