EXPERIMENTAL MORPHOGENESIS 149 



I cannot force you to agree with this postulate : but if 

 you decline you are practically saying that there exists a 

 sort of pre-established harmony between the scientific object 

 and the scientist, the scientist always getting into his hands 

 such objects only as have been predestinated from the very 

 beginning to develop two larvae instead of one, and so on. 



Of course, if that is so, no proof of natural laws is 

 possible at all ; but nature under such views would seem to 

 be really daemonic. 



And so, I hope, you will grant me the postulate of the 

 universality of scientific concepts the only " hypothesis " 

 which we need for our argument.
