PREFACE THIS volume contains the Messenger Lectures which I
delivered at Cornell University in April and May 1934. Chapters n
and vin have been added the remaining chapters correspond to the
twelve lectures of the course. It was one of the conditions of the
lectureship that the lectures should be published. Except for a
small book on the Expanding Universe, my last spell of writing was
about six years ago, when Stars and Atoms 1927, The Nature of the
Physical World 1928 and Science and the Unseen World 1929
practically exhausted all that it was then in my mind to say. A
scientific writer is placed in a difficulty by his earlier books
either his new book will appear as a rather disjointed addendum to
them, or he must perfunctorily go over again a great deal of matter
which he has no wish to rewrite.Being unwilling to adopt the second
alternative, I determined to make what I could of whatever had come
to my mind in the last six years. Accordingly I spoke at Cornell on
a variety of topics, using as a nucleus the material contained in a
number of addresses and lectures which I had had occasion to
deliver since 1929, and adding other subjects to which I had been
giving attention. The general plan was that each lecture should
have a separate theme, except that Indeterminism was spread over
two lectures. The choice of subjects has allowed a certain amount
of continuity of treatment but there has been no attempt to provide
a systematic introduction to modern scientific thought. Perhaps the
biggest gap is the absence of any account of the elementary ideas
of the theory of relativity Vlll PREFACE I could not bring myself
to go over again the ground covered in Chapters I, n, m, vi, vn of
The Nature of the Physical World altering the treatment and
illustrations merely for the sake of alteration. In the opening
lecture I try to explain the philosophical outlook of modern
science, as I understand it, and show how the scientific picture of
the world described in physics is related to the familiar story in
our minds. Chapter n is an interpolation containing a summary of
our knowledge of atomic physics, etc., which some readers may find
necessary for an understanding of subsequent chapters and others
may find useful as a reminder. Then follow four lectures which have
something in common they are concerned with the consequences of the
statistical type of law, first introduced into physics in the
subject of thermodynamics, which has in recent years completely
driven out the older causal type of lawfrom the foundations of
physics. The last of these four lectures, on Probability, has
besides its application to statistical law a more elementary
interest. Then follows a complete change of subject, and the next
four lectures are devoted to astrophysics. Starting with the sun
and familiar stars, we advance to greater distances till we reach
the system of milliards of galaxies which constitutes the universe.
This last subject has been treated more fully in my recent book The
Expanding Universe I here give a much shorter account...
