 ‘Logic’ and ‘ontology’ are big words in philosophy, and different philosophers have used them in different ways. Depending on what these philosophers mean by these words, and, of course, depending on the philosopher’s views, sometimes there are striking claims to be found in the philosophical literature about their relationship. But when Hegel, for example, uses ‘logic’, or better ‘Logik’, he means something quite different than what is meant by the word in much of the contemporary philosophical scene. We will not be able to survey the history of the different conceptions of logic, or of ontology. Instead we will look at areas of overlap that are presently actively debated.
