lopment which is aimed at; except, in a word,
as the adult knowledge is drawn upon as revealing the possible career
open to the child.

It may be of use to distinguish and to relate to each other the logical
and the psychological aspects of experience--the former standing for
subject-matter in itself, the latter for it in relation to the child. A
psychological statement of experience follows its actual growth; it is
historic; it notes steps actually taken, the uncertain and tortuous, as
well as the efficient and successful. The logical point of view, on the
other hand, assumes that the development has reached a certain positive
stage of fulfilment. It neglects the process and considers the outcome.
It summarizes and arranges, and thus separates the achieved results from
the actual steps by which they were forthcoming in the first instance.
We may compare the difference between the logical and the psychological
to the difference between the notes which an explorer makes in a new
country, blazing a trail and finding his way along as best he may,
and the finished map that is constructed after the country has been
thoroughly explored. The two are mutually dependent. Without the more
or less accidental and devious paths traced by the explorer there would
be no facts which could be utilized in the making of the complete and
related chart. But no one would get the benefit of the explorer's trip
if it was not compared and checked up with similar wanderings undertaken
by others; unless the new geographical facts learned, the streams
crossed, the mountains climbed, etc., were viewed, not as mere incidents
in the journey of the particular traveler, but (quite apart from the
individual explorer's life) in relation to other similar facts already
known. The map orders individual experiences, connecting them with one
another irrespective of the local and temporal circumstances and
accidents of their original discovery.

Of what use is this formulated statement of experience? Of what use is
the map?

Well, we may first tell what the map is not. The map is not a substitute
for a personal experience. The map does not take the place of an actual
journey. The logically formulated material of a science or branch of
learning, of a study, is no substitute for the having of individual
experiences. The mathematical formula for a falling body does not take
the place of personal contact and immediate individual experience with
the falling thin
