stone 1 says : " It is almost impossible to over- 

 estimate the appeal which it makes to the in-

Now, this matter of " arrangement " or of 

 " pre-determination," when put forward as an 

 explanation, even tentatively, necessitates a step 

 further. That step might possibly be in the 

 direction of pantheism, though, according to 

 Driesch, 2 pantheism is the doctrine " that reality 

 is a something which makes itself (' dieu sefait* 

 in the words of Bergson), whilst theism would be 

 any theory according to which the manifoldness 

 of material reality is predetermined in an im- 

 material way." And he concludes " that those 

 who regard the thesis of the theory of order as 

 necessary for everything that is or can be, must 

 accept theism, and are not allowed to speak of 

 6 dieu qui se fait.' ' It is difficult to see how 

 anyone who has studied the rigid order exhibited 

 by experiments on Mendelian lines can resist the 

 logic of this argument unless indeed he takes a 

 place on Plate's platform, which admits that a 

 law entails a lawgiver, but declares that of the 

 Lawgiver of Natural Laws we can know nothing. 3 



There is a further point in connection with 

 Mendelian theories which is worth noting in this 

 connection. It would appear that no new factor 

 is ever brought into being, that is, no addition 

 is ever made by variation. According to this
