DISCUSSION 
with other people a common psychological truth. This is the 
universal importance of works of art. The virtues of kindness and 
love and altruism are communicated by them, by the recogni- 
tion that what is psychologically true for me is in some sense also 
psychologically true for you. 
I think that the continuing development of science, and 
particularly of the life sciences, will make a unity of the values 
of science and of our artistic values. It will do so by disseminat- 
ing and illuminating the feeling that human beings do share 
other experiences than those which can be published in scientific 
papers. I am, therefore, not in the least ashamed to be told by 
somebody else that my values, because they are grounded in my 
science, are relative, and his are given by God. My values, in 
my opinion, come from as objective and definitive a source as 
any god, namely the nature of the human being. And they differ 
from those of people who claim that their values come from God 
in only one respect; that the human being is still developing, and 
therefore my values are expanding and changing and are not 
written down on tablets of stone. That makes my values 
richer, I think; and it makes them no less objective, no less real, 
than any values that can be read in the Testaments. 
MacKay: With all due respect, Bronowski has got the cart 
before the horse. What he has said shows in fact that it was the 
concern for truth and the like which begot science, not science 
which begot the concern for truth. Such ethical values are, of 
course, essential to the practice of science, and the more people 
we teach to be scientists the more we should disseminate these 
values. As a matter of historical fact, however, it was mainly 
Christian men, inspired by a more biblical attitude to nature 
than the Aristotelian-scholastic tradition had shown, who 
founded the Royal Society. 
What science (as such) does for us has something of the 
double-edged neutrality of a searchlight. Science can spotlight 
features we would not otherwise have known in the jungle of 
our existence. This makes us responsible both for choosing 
where to point its light, and for making judgments of value in 
the situation it reveals or clarifies.
