of costs and benefits and maximum social gain must be introduced into our formula for
improving the environment.
The task that lies ahead is not an easy one and no single mathematical formula will
provide the answer to the complex problems of science and society as far as the
management of man's environment is concerned. Here I can only suggest a philosophy
which I have found useful in my own career of public service: an eminent British scholar
suggested these thoughts as a guideline for the public servant: "Give me the strength and
fortitude to change those things which can be changed — the patience and peace of mind
not to attempt to change those things that cannot be changed — the good judgement and
wisdom to tell one from the other . . . " May this Conference provide us with improved
knowledge of how to protect our environment for the betterment of man and the wisdom
required to guide ourselves and our leaders on the rational use of this new science and
technology so as to achieve the most beneficial social gains for mankind from our efforts.
