Francisco Suárez, “the prince of modern jurists”, was accused by some of being a great anti-monarchist, even the first regicide, because he was the first “convinced and avowed republican”.
He incorporated Platonist, Aristotelian, Augustinian and Thomist ontology, metaphysics and theodicy within a legal framework; in urisprudence, he introduced the world of ideas into the material world; his discourse on law is valid for his own day and for all time. In dealing with abstract questions, he developed a philosophy of law that is applicable to concrete situations.
