Historically the term «fact» has been a source of philosophical issues. Nietszche for instance said that there are no facts, there are only interpretations and more recently Adrianna Betti has argued that we have no good reason to accept facts in our catalog of the world. Our argument is on the contrary a defense of facts from the ontological point of view (there are facts as a part of our catalog of the world). Such commitment is understood not within a metaphysical framework but within a practice: the law. So, we specifically argue that a world with facts is preferable to a world without them.
