A
Religious Approach to Metaphysics
by Jacques Maritain
Philosophy is the highest of the human sciences,
that is, of the sciences which know things by the
natural light of reason. But there is a science
above it. For if there be a science which is a
participation by man of the knowledge proper to God
himself, obviously that science will be superior to
the highest human science. Such a science, however,
exists: it is theology.
The word theology means the science of
God. The science or knowledge of God which we can
attain naturally by the unassisted powers of
reason, and which enables us to know God by means
of creatures as the author of the natural order, is
a philosophic science -- the supreme department of
metaphysics -- and is known as theodicy or
natural theology. The knowledge or science
of God which is unattainable naturally by the
unassisted powers of reason, and is possible only
if God has informed men about himself by a
revelation from which our reason, enlightened by
faith, subsequently draws the implicit conclusions,
is supernatural theology or simply
theology. It is of this science that we are
now speaking.
Its object is something wholly inaccessible to
the natural apprehension of any creature
whatsoever, namely, God known in himself, in his
own divine life, or in technical language sub
ratione Deitatis, not, as in natural theology,
God as the first cause of creatures and the author
of the natural order. And all theological knowledge
is knowledge in terms of God thus apprehended,
whereas all metaphysical knowledge, including the
metaphysical knowledge of God, is knowledge in
terms of being in general.
The premisses of theology are the truths
formally revealed by God (dogmas or articles
of faith), and its primary criterion of truth the
authority of God who reveals it.
Its light is no longer the more natural light of
reason, but the light of reason illuminated by
faith, virtual revelation in the language of
theology, that is to say, revelation in so far as
it implicitly (virtually) contains whatever
conclusions reason can draw from it.
Alike by the sublimity of its object, the
certainty of its premisses, and the excellence of
its light, theology is above all merely human
sciences. And although it is unable to perceive the
truth of its premisses, which the theologian
believes, whereas the premisses of philosophy are
seen by the philosopher, it is nevertheless a
science superior to philosophy. Though, as St.
Thomas points out, the argument from authority is
the weakest of all, where human authority is
concerned, the argument from the authority of God,
the revealer, is more solid and powerful than any
other.
And finally as the object of theology is he who
is above all causes, it claims with a far better
title than metaphysics the name of wisdom.
It is wisdom par excellence. What relations,
then, must obtain between philosophy and
theology?
***
As the superior science, theology judges
philosophy in the same sense that philosophy judges
the sciences. It therefore exercises in respect of
the latter a function of guidance or government,
though a negative government, which consists in
rejecting as false any philosophic affirmation
which contradicts a theological truth. In this
sense theology controls and exercises jurisdiction
over the conclusions maintained by
philosophers.
***
The premisses of philosophy, however, are
independent of theology, being those primary truths
which are self-evident to the understanding,
whereas the premisses of theology are the truths
revealed by God. The premisses of philosophy are
self-supported and are not derived from those of
theology. Similarly the light by which philosophy
knows its object is independent of theology, since
its light is the light of reason, which is
its own guarantee. For these reasons philosophy is
positively governed by theology, nor has it any
need of theology to defend its premisses (whereas
it defends those of the other sciences). It
develops its principles autonomously within its own
sphere, though subject to the external control and
negative of theology.
It is therefore plain that philosophy and
theology are entirely distinct, and that it would
be as absurd for a philosopher to invoke the
authority of revelation to prove a philosophical
thesis as for a geometrician to attempt to prove a
theorem by the aid of physics, for example, by
weighing the figures he is comparing. But if
philosophy and theology are entirely distinct, they
are not therefore unrelated, and although
philosophy is of all the human sciences
preeminently the free science, in the sense that it
proceeds by means of premisses and laws which
depend on no science superior to itself, its
freedom -- that is, its freedom to err -- is
limited in so far as it is subject to theology,
which controls it externally.
In the seventeenth century the Cartesian reform
resulted in the severance of philosophy from
theology, the refusal to recognize the rightful
control of theology and its function as a negative
rule in respect of philosophy. This was tantamount
to denying that theology is a science, or anything
more than a mere practical discipline, and to
claiming that philosophy, or human wisdom, is the
absolutely sovereign science, which admits no other
superior to itself. Thus, in spite of the religious
beliefs of Descartes himself, Cartesianism
introduced the principle of rationalist
philosophy, which denies God the right to make
known by revelation truths which exceed the natural
scope of reason. For if God has indeed revealed
truths of this kind, human reason enlightened by
faith will inevitably employ them as premisses from
which to obtain further knowledge and thus form a
science, theology. And if theology is a science, it
must exercise in respect of philosophy the function
of negative rule, since the same proposition cannot
be true in philosophy, false in theology.
On the other hand, philosophy renders to
theology services of the greatest value where it is
employed by the latter. For in fact theology
employs in its demonstrations truths proved by
philosophy. Philosophy thus becomes the instrument
of theology, and it is in this respect and in so
far as it serves theological argument that it is
called ancilla theologiae. In itself,
however, and when it is proving its own
conclusions, it is not a bondservant but free,
subject only to the external control and negative
ruling of theology.
As was shown above, philosophy is from the very
nature of things obliged to employ as an instrument
the evidence of the senses, and even, in a certain
fashion, the conclusions of the special sciences.
Theology, considered in itself as a science
subordinate to the knowledge of God and the
blessed, is not in this way obliged to make use of
philosophy, but is absolutely independent.
In practice, however, on account of the nature
of its possessor, that is to say, on account of the
weakness of the human understanding, which can
reason about the things of God only by analogy with
creatures, it cannot be developed without the
assistance of philosophy. But the theologian does
not stand in the same relation to philosophy as the
philosopher to the sciences. We have seen above
that the philosopher should employ the propositions
or conclusions which he borrows from the sciences,
not to establish his own conclusions (at any rate
not conclusions for which metaphysical certainty is
claimed), but merely to illustrate his principles,
and therefore that the truth of a metaphysical
system does not depend on the truth of the
scientific material it employs. The theologian, on
the contrary, makes use at every turn of
philosophic propositions to prove his own
conclusions. Therefore a system of theology could
not possibly be true if the metaphysics which it
employed were false. It is indeed an absolute
necessity that the theologian should have at his
disposal a true philosophy in conformity with the
common sense of mankind.
Philosophy taken in itself normally precedes
theology. Certain fundamental truths of the natural
order are indeed what we may term the introduction
to the faith (praeambula fidei). These
truths, which are naturally known to all men by the
light of common sense, are known and proved
scientifically by philosophy. Theology, being the
science of faith, presupposes the philosophical
knowledge of these same truths.
Philosophy considered as the instrument of
theology serves the latter, principally in three
ways. In the first place theology employs
philosophy to prove the truths which support the
foundations of the faith in that department of
theology which is termed apologetics, which shows,
for example, how miracles prove the divine mission
of the Church; secondarily to impart some notion of
the mysteries of faith by the aid of analogies
drawn from creatures -- as for instance when
theology uses the philosophic conception of
verbum mentale, the mental word, to
illustrate the dogma of the Trinity; and finally to
refuge the adversaries of the faith -- as when
theology shows by means of the philosophic theory
of quantity that the mystery of the
Eucharist is in no way opposed to reason.
We must not forget that, if philosophy serves
theology, it receives in return valuable assistance
from the latter.
In the first place, so far as it is of its
nature subject to the external control and negative
ruling of theology, it is protected from a host of
errors; and if its freedom to err is thus
restricted, its freedom to attain truth is
correspondingly safeguarded.
In the second place, in so far as it is the
instrument of theology, it is led to define more
precisely and with more subtle refinements
important concepts and theories which, left to
itself, it would be in danger of neglecting. For
example, it was under the influence of theology
that Thomism elaborated the theory of nature
and personality, and perfected the theory of
the habitus, habits, etc.
***
Conclusion III. -- Theology, or the science of
God so far as He has been made known to us by
revelation, is superior to philosophy. Philosophy
is subject to it, neither in its premisses nor in
its method, but in its conclusions, over which
theology exercises a control, thereby constituting
itself a negative rule of philosophy.
