248 VITALISM AND SCHOLASTICISM 



Maher puts it * " they are phenomena unex- 

 tended and indivisible, quite beyond the ken of 

 physical science ; and they are never convertible 

 into any of the forms of ' energy ' with which 

 physical science deals. As Tyndall admitted, 

 ' the chasm between them is intellectually 

 impassable.' ' 



" Correlated with mind," says Professor 

 Ward,t " the complex characteristics of all 

 forms of life are intelligible; but to interpret 

 them literally in terms of physical interaction, 

 and apart from mind, is surely impossible." 



In conclusion the writer might perhaps be 

 allowed to say that his first object was to bring 

 forward such biological evidence as had come 

 under his notice in favour of a vitalistic or a 

 neo-vitalistic for as has been shown, the two 

 are identical explanation of living matter. 

 Incidentally only^has it been possible to toucTF 

 on the question of the human soul and its rela- 

 tion to the activities of the human body, which 

 is a matter for theologians rather than for bio- 

 logists to deal with. Nor has he desired to 

 occupy himself with many fascinating, if diffi- 

 cult, philosophical problems such as that for- 

 Scotus mulated by Scotus as to the relations of the 

 operations of the cells or collections of cells into 



* Life and the Conservation of Energy.
