The Unity of the Organism 



just as certainly as though the parts had not been isolated. 

 And so we are able to see what is implied in Harrison's 

 remark quoted above, "we can never 'explain' the processes 

 of normal development with more than a reasonable degree 

 of probability until we succeed in synthesizing organisms." 

 If the condition thus placed on explanation of development 

 is really necessary, such explanation will never be forth- 

 coming, since to synthesize organisms would be to synthesize 

 them endowed with their hereditary attributes and powers 

 in other words, with their ancestral attributes and powers. 

 But in order to synthesize them with such attributes and 

 powers it would be necessary to synthesize not only the 

 organisms, but also their ancestors a rather difficult task.
