his advocacy of instruction in public and private hygiene, lie at the
roots of many of the philanthropic and reformatory movements of the day.

On the whole, Herbert Spencer has been fortunate among educational
philosophers. He has not had to wait so long for the acceptance of his
teachings as Comenius, Montaigne, or Rousseau waited. His ideas have
been floated on a prodigious tide of industrial and social change, which
necessarily involved wide-spread and profound educational reform.

This introduction deals with Spencer's four essays on education; but in
the present volume are included three other famous essays written by him
during the same period (1854-59) which produced the essays on education.
All three are germane to the educational essays, because they deal with
the general law of human progress, with the genesis of that science
which Spencer thought to be the knowledge of most worth, and with the
origin and function of music, a subject which he maintained should play
an important part in any scheme of education.
