LIFE: ITS ORIGIN AND NATURE 41

Philosophy of the Organism,” (2 vols.), and in 
his “History and Theory of Vitalism.” Those 
who are interested in the subject may find an 
exposition of the theory in these works, as well

such works as Jacques Loeb’s “The Dynamics 
of Living Matter,” “The Mechanistic Conception 
of Life,” and Professor Osborne’s “Origin and 
Evolution of Life.”

manifestations, we know but little. It remains 
for the science of the future to determine i 
possible, the precise nature of life. 
THE VEHICLE OF MIND 
We are so accustomed to think of mind as 
being intimately connected with the brain and 
the nervous system that it is almost a shock 
when we realize that this conception is rela¬

had its physical basis or seat in various other 
bodily organs—the heart, the spleen, etc. Now¬ 
adays, the location of the various motor and 
sensory activities of the mental life has been 
carried to such a fine point that it is possible 
to place a finger upon a certain spot or area
