Science
and Faith
by Max Planck
A vast volume of experiences reaches each one of
us in the course of a year; such is the progress
made in the various means of communication that new
impressions from far and near rush upon us in a
never-ending stream. It is true that many of them
are forgotten as quickly as they arrive and that
every trace of them is often effaced within a day;
and it is as well that it should be so: if it were
otherwise modern man would he fairly suffocated
under the weight of different impressions. Yet
every person who wishes to lead more than an
ephemeral intellectual existence must be impelled
by the very variety of these kaleidoscopic changes
to seek for some element of permanence, for some
lasting intellectual possession to afford him a
point d'appui in the confusing claims of
everyday life. In the younger generation this
impulse manifests itself in a passionate desire for
a comprehensive philosophy of the world; a desire
which looks for satisfaction in groping attempts
turning in every direction where peace and
refreshment for a weary spirit is believed to
reside.
It is the Church whose function it would be to
meet such aspirations; but in these days its
demands for an unquestioning belief serve rather to
repel the doubters. The latter have recourse to
more or less dubious substitutes, and hasten to
throw themselves into the arms of one or other of
the many prophets who appear preaching new gospels.
It is surprising to find how many people even of
the educated classes allow themselves to be
fascinated by these new religions -- beliefs which
vary from the obscurest mysticism to the crudest
superstition.
It would be easy to suggest that a philosophy of
the world might be reached from a scientific basis;
but such a suggestion is usually rejected by these
seekers on the ground that the scientific view is
bankrupt. There is an element of truth in this
suggestion, and, indeed, it is entirely correct if
the term science is taken in the traditional and
still surviving sense where it implies a reliance
on the understanding. Such a method, however,
proves that those who adopt it have no sense of
real science. The truth is very different. Anyone
who has taken part in the building up of a branch
of science is well aware from personal experience
that every endeavor in this direction is guided by
an unpretentious but essential principle. This
principle is faith -- a faith which looks ahead. It
is said that science has no preconceived ideas:
there is no saying that has been more thoroughly or
more disastrously misunderstood. It is true that
every branch of science must have an empirical
foundation: but it is equally true that the essence
of science does not consist in this raw material
but in the manner in which it is used. The material
always is incomplete: it consists of a number of
parts which however numerous are discrete, and this
is equally true of the tabulated figures of the
natural sciences, and of the various documents of
the intellectual sciences.
The material must therefore be completed, and
this must be done by filling the gaps; and this in
turn is done by means of associations of ideas. And
associations of ideas are not the work of the
understanding but the offspring of the
investigator's imagination -- an activity which may
be described as faith, or, more cautiously, as a
working hypothesis. The essential point is that its
content in one way or another goes beyond the data
of experience. The chaos of individual masses
cannot be wrought into a cosmos without some
harmonizing force and, similarly, the disjointed
data of experience can never furnish a veritable
science without the intelligent interference of a
spirit actuated by faith. . . .
