In his Metaphysical Disputation 5, Francisco Suárez offers a concise argument to the effect that all that does or can possibly exist is singular and individual, and that a commitment to real universals would entail what he calls a ‘manifest contradiction’. According to a recent interpretation of this Master Argument against realism, it reveals that Suárez was committed to a hylomorphic version of the principle of the identity of indiscernibles, and ruled out the possibility of perfectly similar yet numerically distinct (...) entities. In this paper, however, I argue that (1) at least for fundamental items in his ontology such as immaterial forms and matter-form compounds, Suárez was not committed to the identity of indiscernibles, and (2) a reading of the Master Argument that does justice to this is available. On the basis of this reading I provide a reappraisal of the argument, and conclude that (3) it rests on a premise that the realist would have good reasons to challenge. Hence, while the argument seems consistent with the possibility of indiscernible yet numerically distinct immaterial forms and matter-form compounds Suárez wishes to allow for, it is doubtful whether it can accomplish what it sets out to do, and undermine the case for realism.

The atomist philosopher, David Gorlaeus was a student of theology at the University of Leiden in the Netherlands when he died in 1612 at the age of 21. We know little about his short life, but two works by him, Exercitationes Philosophicae and Idea Physicae, survived and were published posthumously in 1620 and 1651 respectively. They contain the intriguing but often underdeveloped views of a budding philosopher whose ideas might have been completely forgotten but for two later perceptions of his (...) philosophical contribution: one negative and one positive.On the negative side, in 1642 the heretical implications of Gorlaeus’ philosophy were linked to René Descartes when Gijsbert Voetius, the Rector..
