ABSTRACT
This chapter contains discussion of various issues that Russell counted as ontological. There is a section on facts, for in PLA Russell suggested that the most important task for
philosophical logic was to determine what forms of fact there are. The issue is perhaps miscalled ‘ontological’, for it amounts to the question of what language is minimally adequate to describe the world. Russell maintains, in contrast to Wittgenstein of the Tractatus, that in addition to atomic facts there are probably negative facts, certainly general facts, and, he sometimes thinks, possibly in addition facts ‘with more than one verb’, that is, facts involving propositional attitudes.
