imposed on human creative genius by the structure and function of
civilization. In its place we could elaborate a substitute
inter-planetary culture in which a chastened, improved, rejuvenated
humanity could play a creative role, in accordance with our capacities
and our destiny as an integral part of the joint enterprise to which our
sun furnishes light, warmth and vibrant energy. We have latent among us
the talent and genius necessary to play such a part. Do we also have the
imagination, courage and daring to accept the challenge and take our
post of duty in the team that is directing the expansion of our
expanding universe?

SUGGESTED READINGS AND REFERENCES

Among the books consulted in preparation of this essay on civilization
as a social institution, UNESCO _History of Mankind_ holds first place.
The authors describe the work as "the first global history, planned and
executed from an international viewpoint". The subtitle of the six
volumes is "Cultural and Scientific Development".

The work is published under the auspices of the United Nations
Educational, Scientific and Cultural Organization by an International
Commission presided over by Professor Pauls E. deBerredo Carneiro of
Brazil. The Commission consists of 23 members, mostly academicians from
23 countries. The commission also has a corresponding membership of 93
drawn chiefly from the academic personnel of 42 countries.

Textual material for the _History of Mankind _was prepared and edited by
hundreds of experts in the widely ranging fields covered by the
_History_. Final approval of the text came from the Commission. In cases
where there were differences of opinion or of interpretation, varying
and opposing points of view are presented.

_The History of Mankind _is in six volumes.

I. Prehistory and The Beginnings of Civilization.

II. The Ancient World.

III. The World A.D. 400 to A.D. 1300.

IV. The World A.D. 1300 to the End of the Eighteenth Century.

V. The World in the Nineteenth Century.

VI. The Twentieth Century. All but the first volume of the _History_
deal with the epoch during which civilization has played a fateful role
in world affairs.

Professor Arnold J. Toynbee's ten volume _Study of History_ is concerned
chiefly with the rise and decline of those civilizations which have left
a noteworthy historical record. His emphasis is geographical and
political rather than cultural and social. The same thing may be said of
