If mankind is now to go down
in a wrack of war, starvation, bankruptcy, and ruin, the sunset sky at
least is glorious.

And there is tonic in another thought which rises from the very nature
of this recent blossoming of knowledge. It marks the growing
co-operative activity of mankind. The fact that science and research of
every kind have advanced so rapidly is not only, or even primarily, a
proof of the continued vigour of the human intellect, but of the
stability of society, the coherence of social classes and nations, the
readiness of the bulk of men to allow their more immediately productive
work to be used for the support of those whose labours are in a more
remote and ideal sphere. Science did not begin until the ancient
priesthoods were enabled to pursue disinterested inquiries without the
need of earning their daily bread. Civilization, we may be assured, is
not threatened in its most vital part so long as the general will
permits the application of the general resources to the promotion of
learning and research without a claim for immediate marketable results.
Our last generation has not only permitted but has encouraged this in
all Western countries, and in other countries, such as China and Japan,
influenced by the West. The money thus spent is vastly greater than in
any equal period before, and the United States, the land of the fullest
democratic claims, is also the land of the amplest generosity for
scientific and educational purposes.

The growth of knowledge is a symptom not only of the collective capacity
of living man but also of the continuity of the present age with those
which had laid the earlier foundations. One school of vigorous action,
and still more vigorous talk, advises our generation to be done with the
past and make a fresh start on more ideal lines. This is not the voice
of science, which, just in proportion to its growth, has shown more and
more care for its origins and its past: and this is true at every stage
in the history of thought. The Greeks, fighting for freedom and
establishing in the city-state a new form of political organization for
the world, were yet in their scientific evolution true and grateful
successors of the priests who first compiled the observations necessary
for the scientific study of the heavens and founded the art of medicine.
The men of the Renascence, who were burnt and imprisoned for doubting
the verbal inspiration of Aristotle and the Bible, were in fact go
