Biological Future of Man 
contributions were less competitive, did not need endless per- 
suasion and repetition to be heard; the challenge was the struggle 
with nature. The complication of science has made it inexorably 
more human—or should we ever have forgotten this limit to 
objectivity ? 
Man’s future as a biologist surely depends on the rationaliza- 
tion of scientific communication. Society makes many demands 
on the energies of the global community of science. We must 
also take care to look to the preservation of our own future by 
the modernization of our own techniques for efficient but free 
expression. 
The theme of this paper was to have been molecular biology, 
the transfer of information from one macromolecule to another. 
It has become an essay on communication, under the same logic 
by which man has evolved from substance to concept.
