Today the expression scientific realism designates a broad (perhaps too broad) range of epistemological conceptions against which stands an even broader range of "anti-realist" conceptions. We shall not survey these positions, nor enter the critical discussion concerning their merits and shortcomings. Our goal is much more practical. Since it is clear from the whole of the foregoing discourse that we advocate a form of scientific realism (because we have maintained that 'scientific objects are real"), we want to make more precise and explicit which form of realism we advocate and at the same time give (or better recapitulate and restate) the fundamental reasons we have found for maintaining realism.
