think, received the attention it deserves. To the mind of the 

 physiologist, all changes must be correlated with others. 



In what sense has the line that evolution has taken been 

 predetermined ? In the sense that all things in the universe 

 are unstable, are undergoing change, leading to new forms and 

 qualities of such a character that they result in a gradual prog- 

 ress toward what our minds can not but consider higher mani- 

 festations of being. 



The secondary methods according to which this takes place 

 constitute the laws of nature, and as we learn from the prog- 

 ress of science are very numerous. The unity of nature is a 

 reality toward which our conceptions are constantly leading 

 us. Evolution is a necessity of living matter (indeed, all matter) 

 as we view it.
