THE GOAL OF EVOLUTION 247 



emancipate themselves from the tyranny of language and 

 culture. And there may even be latent in man, although 

 most scientists think it very unlikely, some powers of com- 

 munication like telepathy which transcend the known hori- 

 zons of our day. The latter possibility conjures up the pic- 

 ture of a race with the faculty of communicating certain 

 contents of mind without the limitations and distortions of 

 symbols, and without the deceit and trick of the organized 

 lie. J. B. Rhine, S. G. Soal, and others have, at least, estab- 

 lished a hint that there is a possibility, remote as it may be, of 

 some degree of this faculty developing in man. 



In the meantime, however, man has only one sure way to 

 take the fullest advantage of the capacities of the brain he 

 now possesses, and that is by a complete and honest appraisal 

 of the symbols and signs of his present means of communi- 

 cation. He must free himself from the enslavement of 

 words. He must find the way that Socrates long ago pointed 

 out— to "convey knowledge," not just to "convey belief 

 without knowledge." Science and operational philosophy 

 are now at the frontier ready to shake off the culture-tram- 

 meled understanding of the past, to revise their dialects and 

 their dialectics, to re-examine the linguistic background of 

 their thinking and, for that matter, of all thinking. There is 

 a wide and rapidly growing attack on the problem of com- 

 munication and on the nature of man launched by students 

 of semantics, by Wiener's analogies of cybernetics, by stu- 

 dents of the main mind-brain problem, by the Rashevsky 

 school of mathematical biology, by physics and psychology 

 and the sciences of evolution, and by many scientists turned 

 philosopher and philosophers turned scientist. A true sci- 

 ence of man is emerging. 



Even with all the emphasis and knowledge that may 

 come through this new science of man, the problems of the 

 future will require for their solution the highest levels of un- 

 selfishness, intelligence, and imagination.
