<h2><SPAN name="PREFACE" id="PREFACE">PREFACE</SPAN></h2>
<p>The history of science has something to offer to the humblest
intelligence. It is a means of imparting a knowledge of scientific facts
and principles to unschooled minds. At the same time it affords a simple
method of school instruction. Those who understand a business or an
institution best, as a contemporary writer on finance remarks, are those
who have made it or grown up with it, and the next best thing is to know
how it has grown up, and then watch or take part in its actual working.
Generally speaking, we know best what we know in its origins.</p>
<p>The history of science is an aid in scientific research. It places the
student in the current of scientific thought, and gives him a clue to
the purpose and necessity of the theories he is required to master. It
presents science as the constant pursuit of truth rather than the
formulation of truth long since revealed; it shows science as
progressive rather than fixed, dynamic rather than static, a growth to
which each may contribute. It does not paralyze the self-activity of
youth by the record of an infallible past.</p>
<p>It is only by teaching the sciences in their historical development that
the schools can be true to the two principles of modern education, that
the sciences should occupy the foremost place in the curriculum and that
the individual mind in its evolution should rehearse the history of
civilization.</p>
<p>The history of science should be given a larger place than at present in
general history; for, as<span class="pagenum"><SPAN name="Page_vi" id="Page_vi">[Pg vi]</SPAN></span> Bacon said, the history of the world without a
history of learning is like a statue of Polyphemus with the eye out. The
history of science studies the past for the sake of the future. It is a
story of continuous progress. It is rich in biographical material. It
shows the sciences in their interrelations, and saves the student from
narrowness and premature specialization. It affords a unique approach to
the study of philosophy. It gives new motive to the study of foreign
languages. It gives an interest in the applications of knowledge, offers
a clue to the complex civilization of the present, and renders the mind
hospitable to new discoveries and inventions.</p>
<p>The history of science is hostile to the spirit of caste. It shows the
sciences rising from daily needs and occupations, formulated by
philosophy, enriching philosophy, giving rise to new industries, which
react in turn upon the sciences. The history of science reveals men of
all grades of intelligence and of all social ranks coöperating in the
cause of human progress. It is a basis of intellectual and social
homogeneity.</p>
<p>Science is international, English, Germans, French, Italians,
Russians—all nations—contributing to advance the general interests.
Accordingly, a survey of the sciences tends to increase mutual respect,
and to heighten the humanitarian sentiment. The history of science can
be taught to people of all creeds and colors, and cannot fail to enhance
in the breast of every young man, or woman, faith in human progress and
good-will to all mankind.</p>
<p>This book is intended as a simple introduction, taking advantage of the
interests of youth of from<span class="pagenum"><SPAN name="Page_vii" id="Page_vii">[Pg vii]</SPAN></span> seventeen to twenty-two years of age (and
their intellectual compeers) in order to direct their attention to the
story of the development of the sciences. It makes no claim to be in any
sense complete or comprehensive. It is, therefore, a psychological
introduction, having the mental capacity of a certain class of readers
always in view, rather than a logical introduction, which would
presuppose in all readers both full maturity of intellect and
considerable initial interest in the history of science.</p>
<p>I cannot conclude this preface without thanking those who have assisted
me in the preparation of this book—Sir William Osler, who read the
first draft of the manuscript, and aided me with his counsel; Dr.
Charles Singer, who read all the chapters in manuscript, and to whom I
am indebted for advice in reference to the illustrations and for many
other valuable suggestions; the officers of the Bodleian Library, whose
courtesy was unfailing during the year I worked there; Professor Henry
Crew, who helped in the revision of two of the chapters by his judicious
criticism; Professor J. E. Rush, whose knowledge of bacteriology
improved the chapter on Pasteur; Professor L. O. Grondahl, who read one
of the chapters relating to the history of physics and suggested
important emendations; and Dr. John A. Brashear, who contributed
valuable information in reference to the activities of Samuel Pierpont
Langley. I wish to express my gratitude also to Miss Florence Bonnet for
aid in the correction of the manuscript.</p>
