genius are but the result of the clash of atoms and 

 the impact of molecules. Intellectual work is the 

 correlative of certain brain-waves ; thrills of grati- 

 tude, and love of friends and country, are mere 

 oscillations of infinitesimal particles of brute matter. 

 Pleasure and pain, joy and sorrow, are the direct 

 product of vibratory motion, and the difference in 

 the nature of these emotions arises solely from the 

 difference in the character of the generating shakes 

 and quivers. Like Cabanis, Haeckel makes thought 

 a secretion of the brain, and holds, with Vogt, that 

 the brain secretes thought as the liver secretes bile. 

 With Moleschott, he would assert that thought is 

 dependent on phosphorus, and with Biichner he 

 would declare it to be a product of nervous elec- 

 tricity. In the words of Caro, he teaches that : " In 

 matter, resides the principle of movement ; in move- 

 ment, is the reason of life ; in life, is the reason of 

 thought." Hence, in returning to the first term of 

 the series, we observe that thought and life are only 

 forms of movement, which is the original inherent 

 property of eternal matter. 1 



With Hugo, Haeckel would exclaim : 



" Learn that everything knows its law, its end, 

 its way ; . . . 



That everything in creation has consciousness. 



Winds, waves, flames, 



Trees, reeds, rocks, all are alive ! All have 

 souls . . . 



Compassionate the prisoner, but compassionate 



the bolt ;
