 and you will discover the source of the genius, 

 a mere trickle at first, then a stream, then a 

 mighty river. 



The darkness that lies behind that word

 throw a little light upon it and has succeeded 

 only In making unto itself a barbarous jargon, 

 leaving obscurity more obscure than before. 

 As for us, who hunger after lucidity, let us 

 relinquish abstruse theories to whoso delights

 shall we find that subject? There would be 

 a host of them and magnificent ones, if It were
