EDITOR'S PREFACE.
This second volume contains the further investigations of Professor
Preyer on the mind of the child. The former volume contained the first
and second portions, devoted respectively to the development of the
senses and of the will. The present volume contains the third part,
treating of the development of the intellect; and three appendixes are
added containing supplementary matter.
Professor Preyer considers that the development of the power of using
language is the most prominent index to the unfolding of the intellect.
He differs with Professor Max Mueller, however, on the question whether
the operation of thinking can be carried on without the use of words
(see the recent elaborate work of the latter on "The Science of
Thought").
At my suggestion, the painstaking translator of this book has prepared
a full conspectus, showing the results of Professor Preyer's careful
observations in a chronological order, arranged by months. This
considerable labor will render the book more practical, inasmuch as it
will enable each reader to see at a glance the items of development of
the child in the several departments brought together in epochs. This
makes it possible to institute comparative observations under the
guidance of Professor Preyer's method. I think that I do not exaggerate
the value of this conspectus when I say that it doubles the value of the
work to the reader.
