Ontologism is a philosophical system most associated with Nicholas Malebranche (1638–1715) which maintains that God and divine ideas are the first object of our intelligence and the intuition of God the first act of our intellectual knowledge.^[1] Nicolas Malebranche was a source for many later philosophers of Ontologism such as Antonio Rosmini-Serbati. The Holy Office condemned Ontologism in 1861 as unsafe for teaching (tuto tradi non possunt).^[2]
