 is really the law of reasoned thought, which I 

 have repeatedly used against the false con-

Professor Plate next proceeded to establish more 

 firmly what he had said about my twofold character. 

 He referred to the problem of the existence of matter, 

 and said : ' We scientists maintain that matter 

 exists, that nothing is formed out of nothing, and 

 that matter is everlasting. We cannot accept 

 the theory that matter was created, and if we did 

 accept it, we should be no better off. We are modest 

 enough to dispense with a further solution of this 

 problem.'

 monistic philosopher. The scientist may say : 

 ' I know nothing about the origin of matter,' 

 but he must not say that matter is therefore 

 everlasting; for a statement of this kind 

 belongs to philosophy with its metaphysical 

 problems. To assume the eternity of matter
