ambassador's own investigation was of the opinion that Anselm's body had been confused with Archbishop Theobald's and likely remained entombed near the altar of the Virgin Mary, but in the uncertainty nothing further seems to have been done then or when inquiries were renewed in 1841. Writings Anselm has been called "the most luminous and penetrating intellect between St Augustine and St Thomas Aquinas" and "the father of scholasticism", Scotus Erigena having employed more mysticism in his arguments. Anselm's works are considered philosophical as well as theological since they endeavor to render Christian tenets of faith, traditionally taken as a revealed truth, as a rational system. Anselm also studiously analyzed the language used in his subjects, carefully distinguishing the meaning of the terms employed from the verbal forms, which he found at times wholly inadequate. His worldview was broadly Neoplatonic, as it was reconciled with Christianity in the works of St Augustine and Pseudo-Dionysius, with his understanding of Aristotelian logic gathered from the works of Boethius. He or the thinkers in northern France who shortly followed him—including Abelard, William of Conches, and Gilbert of Poitiers—inaugurated "one of the most brilliant periods of Western philosophy", innovating logic, semantics, ethics, metaphysics, and other areas of philosophical theology. Anselm held that faith necessarily precedes reason, but that reason can expand upon faith: "And I do not seek to understand that I may believe but believe that I might understand. For this too I believe since, unless I first believe, I shall not understand". This is possibly drawn from Tractate XXIX of St Augustine's Ten Homilies on the First Epistle of John: regarding John 7:14–18, Augustine counseled "Do not seek to understand in order to believe but believe that thou may understand". Anselm rephrased the idea repeatedly and Thomas Williams considered that his aptest motto was the original title of the Proslogion, "faith seeking understanding", which intended "an active love of God seeking a deeper knowledge of God". Once the faith is held fast, however, he argued an attempt must be made to demonstrate its truth by means of reason: "To me, it seems to be negligence if, after confirmation in the faith, we do not study to understand that which we believe". Merely rational proofs are always, however, to be tested by scripture and he employs Biblical passages and "what we believe" () at times to raise problems or to present erroneous understandings,
