Abstract

Descartes argued that the eternal truths, most prominently the truths of mathematics, are created by God. He was not explicit, however, about the ontological status of these truths. Interpreters have proposed interpretations ranging from Platonism and conceptualism. I argue for an intermediate interpretation: Descartes held they have objective being in God’s mind. In this regard his view was line with a prominent view in Aristotelian scholasticism. I defend this interpretation against objections based on divine simplicity and concerns about causation. I raise questions about the philosophical merit of these objections, but in addition I argue that there is good reason to think that Descartes himself did not think they were problems for the view. Seemingly conceptualist passages in the Principles, I argue, in fact address issues different from the ontological status of the eternal truths.
