In short, psychophysics, in the form in which it appears here, is still a doctrine in
the first state of becoming; Thus, the title of these writing elements is not unjustly
understood, as if it were an illustration of the essentials of an already founded and
formed doctrine, an elementary textbook; but rather to depict the beginnings of a
doctrine that is still found in the elementary state. So do not make any claims to this
writing, which are to be made to an elementary textbook. In many cases it gives
examinations, explanations, and compilations which would be quite inappropriate in
such a case, but which can contribute to making it possible for such a textbook to
become possible. What was to be demanded
Just as little as an elementary textbook, one has here to look for a collection of the
entire material of psychophysics, but preferably only that which belongs to the
foundation of the psychophysical theory of measurement and enters into its
applications. Innumerable things that are an object of psychophysics could not find a
place here, because it has not yet reached the stage of being able to find a picture in
it.
Even though many things in this text are already too much, some are too few, one
has cause at any rate to be indulgent in this regard, since formally there was almost
nothing, materially only completely scattered, on which I could base myself and call
myself; but a house can not be built without bringing stones to it; and where the plan
can still be built in front of the house, in the first attempt, everything can not be all
right and the right measure. Each successive attempt of this kind will be more
complete on one side and shorter and more precise on the other.
It is no less true than with regard to the formal defects that I have to claim the
leniency of the errors of fact which may have been left in this work, especially in the
treatment of many fine, difficult, and new questions, and more so in what follows as
being in this parts. In the long course of these investigations, I have gone through so
many erroneous and uncertainties with fixed and steadily established general
principles. The whole area was previously buried in obscurity. That I dare not dare to
do so with the present editors to have everyone behind me. But I would not be able to
give these examinations if I wanted to wait for complete assurance in this regard; and
yet have the confidence that,
Lastly, it will only be wondering if what is offered and what is offered here is a
durable and fruitful beginning. If you find it, do not take the missing and the mistakes
too high; it will at least be their merit to have produced the better.
I am far from saying that what is in this document is something completely new,
and it would be a bad recommendation if it were. On the contrary, in order to do
justice to just claims for priority from the outset, and at the same time to show that
the writing is subject to something more than a subjective idea, I touch upon a few
historical points in the preface, which I refer to in its place and finally in a special
historical one Chapter closer.
