_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 indivi
