This chapter was originally written for an event honouring E. J. Lowe. The author considers Lowe a philosopher of the first rank, a philosopher who has resisted the idea that philosophical problems are to be addressed in ways that keep ontology at arm's length. Lowe's work is a fine example of what the Australians call ontological seriousness. The remarks presented in the chapter are meant less as objections to Lowe's 'four-category ontology' than as requests for clarification. Lowe and David Armstrong agree that universals depend on their instances; the instances are 'metaphysically prior' to the universals. The chapter presents Lowe's account of dispositionality. The discussion is concluded by mentioning three aspects of Lowe's view. First, according to Lowe kinds depend on attributes that characterize them. Second, Lowe tells us that kinds are characterized by attributes, properties, and relations regarded as universals. Third, is an instance of the salt kind.
