DISCUSSION 
for science as if it were in competition with religion in these 
matters. Whatever the merits of particular religions, they are 
logically no more rivals of science than a compass is of a map. 
From a Christian standpoint at any rate, I believe that God 
expects a man to do equal justice to scientific and to religious 
knowledge, since He is the giver of both. 
Crick: The considerable degree of agreement which cer- 
tainly can be reached between “biological humanists”? and 
people with a Christian background appears to me to be an 
historical accident. When one first discards Christian belief, 
more of the ethics and the patterns of thought remain than one 
could possibly anticipate until over the years one has thought 
about a large number of issues like these we have been discussing. 
I foresee that if we were to remove the Christian ethic completely 
(or those of any other religious system) and simply go on 
roughly, by a rule of thumb, with our biological knowledge, 
we might well come to a quite different set of ethical values. 
But I do not see how these can be given a Jogical justification. 
I do not think they will be the same as the present ones for the 
reason that MacKay gave, namely, that all the time new facts 
and values are being fed into the system; society can in fact 
develop in different ways and may thus end up with different 
stable systems of thought. It is perfectly true, as Bronowski 
says, that in order to pursue science you have to have certain 
values concerning truth and so forth, but they do not necessarily 
coincide sufficiently with the Christian values for other practical 
purposes. Take the suggestion of making a child whose head 
is twice as big as normal. There is going to be no agreement 
between Christians and any humanists who lack their particular 
prejudice about the sanctity of the individual, and who simply 
want to try it scientifically. One must face the fact that there 
is eventually bound to be a conflict of values. It is hopeful that 
at the moment we can get a measure of agreement, but I think 
that in time the facts of science are going to make us become less 
Christian. 
Haldane: We have left out what may be the most important 
ethical fact about applied science, namely, that it magnifies
