Abstract

The centenary of the Louvain Institute of Philosophy (which was founded to contribute to a renewal of philosophy within the Christian community „by adhering as closely as possible to the doctrine of Thomas Aquinas”) is the occasion for a critical examination of the particular form of Thomism developed by Désiré Mercier, the first president of the Institute. In Mercier's view, the appeal to Thomas can not be a submission to tradition or authority. Since philosophy is always a personal, free, rational investigation, the only reason for adhering to a certain doctrine, is its intrinsic philosophical value. The mean argument for preferring Thomas „in philosophicis” is the fact that he „combines observation and rational-speculation, analysis and synthesis”, whereby all empirical facts are integrated and made intelligible in a larger metaphysical frame. By so doing Thomas avoids the extremes of empiricism, which leads to materialism, and idealism, which goes hand in hand with dualistic spiritualism. One may doubt whether this is a good characteristic of the „essence of Thomism”. However, Mercier follows Thomas, not so much for any original doctrine, but because he best represents the great scholastic tradition starting from Aristotle. This tradition should not be admired as an ideal of perfection that cannot be improved upon, but should be further developed and renewed, especially by integrating the achievements of modern experimental investigations within it. (Besides the sciences, we should expect not too much from modern philosophy, except in the discussion of the „critical problem”). Mercier thus bases his philosophical option for Thomism on his judgment that it better than any other philosophy offers a metaphysical synthesis within which the investigations of the modern sciences can be integrated, while at the same time being in concordance with the Christian view on man and world. However, when one studies the Thomism as elaborated in Mercier's manuals, it turns out that his attempt at integration fails. For there is no intrinsic link between the scientific findings he considers and the philosophical theses he develops. Herein lies the inherent weakness of the neo-scholastic construction as it was advocated by Mercier. When one defends Thomism by arguing that it offers a „comprehensive synthesis of all knowledge”', and at the same time one stresses the autonomy of scientific inquiry without apologetic intentions, one can expect that as these sciences develop, there will also arise the need for new conceptual schemes and new philosophical models which better fit these new findings. At that moment Thomistic doctrine also seems to fall away as a superfluous superstructure. One can argue that Mercier too easily understood philosophy as a „natural complement” of the sciences and that for that reason he could not really succeed in renewing Thomism. Most neothomists will try to base their option for Thomas upon the originality of his metaphysics. But this search for the „essence of Thomism” is problematic. At the end of the paper it is argued that no intrinsic philosophical arguments can be given for a normative preference for Thomas. The demand to philosophize „ad mentem Thomae” only makes sense when the relation of reason to faith is considered. As É. Gilson has shown, most neothomists were reluctant to develop this argument, except in a negative way : to argue for the autonomy of their philosophical (thomistic) arguments (although they were, in fact, motivated by a religious interest)
