Abstract

The debate about the relation between science and truth is manifestly epistemological, but latently and fundamentally metaphysical. Popper's theory of verisimilitude provides us with a striking example. According to Popper, science aims at bringing us nearer to 'absolute, objective truth'; the growth of scientific knowledge is seen as a never ending realisation of that ultimate aim. This thesis of verisimilitude can be interpreted in two ways. In the first interpretation the thesis appears as a correct, but formal and even trivial statement. Here the thesis that science aims at bringing us nearer to truth is as unilluminating as the thesis that moral endeavor aims at bringing us nearer to the Moral Good or that artistic endeavor aims at bringing us nearer to Aesthetic Beauty. According to the second interpretation, however, the thesis has a more substantial and metaphysical meaning. Here it consists of three different claims : 1. scientific endeavor points to something which is beyond and actual or humanly possible scientific achievement; 2. it is in this relation with something transcendent that the ultimate purpose of science is to be sought; 3. the relation between actual science and its transcendent should be seen as a part-whole relation, i.e. the transcendent goal should be represented as the ideal of total intelligibility. In this article the first and second claim are accepted; the third is rejected. One should accept the idea (put forward by Einstein ) that science points to a mystery beyond science. One should beware, however, of equating the sense of mystery with an anticipation for yet hidden information, inaccessible to us, but 'quoad se' accessible to reason. Science's transcendent mystery should be viewed in a more radical way. That is to say, the relation between actual science and its transcendent mystery is analogous to the relation between, on the one hand, the information contained in and derivable from a (good) poem and, on the other hand something else which is poetically suggested, yet does not consist in hidden information. What is evoked by poetry and science, is not even in principle translatable in terms of an informative content. Therefore the ultimate goal of science is not the ideal of knowing everything with the clarity and precision of science ; it is rather the awareness of a mystery which does not even exist as the sort of intelligible content scientific theories attempt to mirror
