Semantics, Hermeneutics, Statistics: Some Reflections on the Semantic Web

We start with the ambition – dating back to the early days of the semantic web – of assembling a significant portion human knowledge into a contradiction-free form using semantic web technology. We argue that this would not be desirable, because there are concepts, known as essentially contested concepts, whose definitions are contentious due to deep-seated ethical disagreements. Further, we argue that the ninetenth century hermeneutical tradition has a great deal to say, both about the ambition, and about why it fails. We conclude with some remarks about statistics.
