Descartes’ vindication of Cartesianism against the charges of Gisbert Voet (1588–1676). Through a number of dissertations which he supervised at the University of Utrecht, Henricus Regius (1598–1679) had been promoting Descartes’ views on the human mind, seen as denying the immortality of the soul, and this and Descartes’ Copernicanism and scepticism were regarded by Voet as undermining the foundations of Calvinist theology as taught at Utrecht. Failing to get Regius removed from the chair of medicine at the university, Voet directed his attacks at Descartes himself. Cartesian thought was officially condemned by the University and Descartes feared being expelled from the Dutch Republic where he had lived since 1628. This undoubtedly contributed to his decision to accept Queen Christina’s invitation to Sweden in 1649.
This is one of Descartes’ rarest works.
