DISCUSSION 
as that negroes have thick lips and white people have moder- 
ately thick ones and the Chinese have thinner ones. These are 
not the trivialities they seem, but tremendous barriers, likely 
to produce all sorts of failures of communication and aggression 
because they are part of the communication system. It is very 
interesting that the anthropologists’ classification of races is 
nearly all on what they call “characters unimportant for sur- 
vival’. Yet these are nearly all facial characters concerned 
with communication! This seems another area where under- 
standing really should improve quite rapidly and is likely to do 
so because people are now aware of the problems. 
Incidentally, so much of what we talk about we know only 
from our own point of view in our own culture. I wonder if 
anybody knows what is the attitude, for example, of the Chinese 
population or intellectuals to humanity being one race? How 
much do we know about the development of ideas on these 
fundamental themes in other cultures? 
Coon: ‘The Chinese don’t like that idea at all. Ever since 
the Communists have been in power they have been spending 
a lot of money sending palaeontologists around to fill the gap 
between Sinanthropus man who is about 400,000 years old and 
the upper cave people who are about 10,000 years old. This 
is so that they can prove Weidenreich’s theory of the continuity 
of the evolution of the Mongoloids apart from the rest of man- 
kind. Now they have got six skulls that fill that gap and they 
feel very happy about it. 
Haldane: Dr. Hoagland said that all scientists think deter- 
ministically. I don’t think that I do. I have come to the 
conclusion that my subjective account of my own motivation 1s 
largely mythical on almost all occasions. My mother used to 
ask me, “‘Why did you do that?’’, and I learned to give a list 
of motives. Looking back I think I was generally wrong. I 
don’t know why I do things. 
Secondly, in my opinion if a chess-playing machine is pur- 
posive, natural selection is also purposive by the same criteria. 
I am in fundamental agreement with Dr. Chisholm, but I 
think he is a little rough with the human race when he says it
