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.

THE MIND OF THE CHILD.

THIRD PART.

_DEVELOPMENT OF THE INTELLECT._

The development of the intellect depends in so great measure upon the

modification of innate endowments through natural environment and

education, even before systematic instruction begins, and the methods of

education are so manifold, that it is at present impossible to make a

complete exposition of a normal intellectual development. Such an

exposition would necessarily comprise in the main two stages:

1. The _combination_ of sensuous _impressions_ into _perceptions_

(Wahrnehmungen); which consists essentially in this--that the sensation,

impressing itself directly upon our experience, is by the intellect, now

beginning to act, co-ordinated in space and time.

2. The _combination_ of _perceptions_ into _ideas_; in particular into

_sense-intuitions_ and _concepts_. A sense-intuition (Anschauung) is a

perception together with its cause, the object of the sensation; a

concept (Begriff) results from the union of the previously separated

perceptions, which are then called separate marks or qualities.

The investigation of each of these stages in the child is in itself a

great labor, which an individual may indeed begin upon, but can not

easily carry through uniformly in all directions.

I have indeed tried to collect recorded facts, but have found only

very little trustworthy material, and accordingly I confine myself

essentially to my own observations on my child. These are not merely

perfectly trustworthy, even to the minutest details (I have left out

everything of a doubtful character), but they are the most

circumstantial ever published in regard to the intellectual

development of a child. But I have been acquainted with a sufficient

number of other children to be certain that the child observed by me

did not _essentially_ differ from other healthy and intelligent boys

in regard to the principal points, although the time at which

development takes place, and the rapidity of it, differ a good deal in

different individuals. Girls often appear to learn to speak earlier

than boys; but further on they seem to possess a somewhat inferior

capacity of development of the logical functions, or to accomplish

with less ease abstractions of a higher order; whereas in boys the

emotional functions, however lasting their reactions, are not so

delicately graduated as in girls.

Without regard to such differences, of which I am fully aware, the

following chapters treat exclusively of the development of purely

intellectual cerebral activity in both sexes during the first years.

I acknowledge, however, that I have found the investigation of the

influence of the affectional movements, or emotions, upon the

development of the intellect in the child during the first years

so difficult, that I do not for the present enter into details

concerning it.

The observations relate, first, to the non-dependence of the child's

intellect upon language; next, to the acquirement of speech; lastly,

to the development of the feeling of self, the "I"-feeling.
