In assuming his post of Professor of Philosophy at the University of Franeker, Ruardus Andala expounded in his Oratio inauguralis de physicae praestantia, utilitate et iucunditate (1701) his aim to replace Scholastic-Aristotelian philosophy with more recent philosophical and scientific theories as the rational foundation of theology. In this paper, Andala’s program is reconstructed by taking into account his later works, where he abandoned his former predilection for Jean Leclerc’s Physica (1696), replacing it with René Descartes’s Principia philosophiae (...) (1644), complemented with ideas inspired by the philosophia experimentalis of Francis Bacon and Robert Boyle. (shrink)
