Harvard University. In a real sense, both may be regarded as sponsors
of the work. I would also like to acknowledge with gratitude a grant
from the Carnegie Corporation to support my "basic research on
problems of modernization and development in historical and com-
parative perspective."

In conclusion, I should note that I have edited the chapters with
three purposes in mind: first, to delete as much repetitious material
as possible, since different articles on related subjects which appear in
different journals often include some repetition to enable the reader
of any given one to follow the argument; second, I have brought a
few up to date, so as to cover materials or events that were not dealt
with in the original publication; and third, I have sometimes changed
the opening or conclusion of the articles to stress the link with mate-
rial that precedes or follows them in this book.
