I think Lyotard meant that when science attempts to use observation to "prove" truth rather than just to provide utilitarian guidelines (or in Lyotard's words, "useful regularities"), it necessarily employs metaphysics, a branch of philosophy, to legitimate its claims. Of course it does not do so overtly as that would undermine its claims as truth based. This "legitimation" of science as truth is so pervasive that it has entered the realm of common sense for the average person. Through a metanarrative of its own called positivism, science claims that "positive knowledge is based on natural phenomenon... as verified by observation" - Webster) and further that this positive knowledge is absolute truth. Events over the last decade in the scientific world such as the shift from Newtonian physics to quantum physics have shown that what was once thought to be absolute knowledge is only transitory. This has undermined scientific truth claims and shown science to be just another, if very useful, metaphysics. The poststructuralist Challenge of the metanarrative of science as truth and its resultant role in determining modern culture has been one of the most important postmodern shifts. I think that's why Lyotard mentioned it so early in his introduction. Don
