Proslogion is a short medieval devotional and philosophical work composed by Anselm of Canterbury in the late 11th century. It presents a set of meditations and arguments intended to demonstrate the existence and nature of God, combining theological devotion with philosophical reasoning. The work influenced scholasticism, monastic spirituality, and later debates in metaphysics and apologetics.

Background and Composition

Anselm of Canterbury wrote the work during his first tenure at Canterbury Cathedral under the influence of figures such as Lanfranc of Bec, Pope Gregory VII, William II of England, Benedict of Nursia, Bernard of Clairvaux, Peter Lombard, Hildegard of Bingen, Bede, Alcuin, John of Salisbury, Odo of Bayeux, Eadmer, Osbern of Canterbury, Lanfranc's reforms, Norman Conquest, Investiture Controversy, Cluny Abbey, Merton Priory, Rochester Cathedral, Wulfstan II, Dunstan, Lanfranc's pastoral care, William of Malmesbury, Orderic Vitalis, Anselm's exile, Archbishopric of Canterbury, Gregorian Reform, Saint Anselm's relics, Purgatory debates, Medieval Latin literature, Monasticism contributed to his intellectual milieu. Composed as a brief meditation for private devotion and instruction, the text responds to monastic practice at Bec Abbey and the episcopal duties of the archbishopric, reflecting encounters with papal authority like Pope Urban II and political actors such as King Henry I.

Structure and Content

The work is organized into a sequence of numbered meditations that move from prayerful addresses to analytic claims about divine attributes. Anselm frames his reflections in the context of Canterbury's liturgical calendar and the monastic schedule influenced by Rule of Saint Benedict, referencing exemplars such as Augustine of Hippo, Boethius, Bonaventure, Thomas Aquinas, Duns Scotus, William of Ockham, Albertus Magnus, Peter Abelard, Roscelin of Compiègne, Hugh of Saint Victor, Isidore of Seville, Gregory the Great, Jerome, Aquinas' Summa Theologica in later reception. The meditations evolve to present distinct ontological assertions by means comparable to later scholastic disputations found in Summa Contra Gentiles and medieval disputation manuals from Paris and Oxford.

Philosophical Arguments and Themes

Central to the text is an argument asserting that God is "that than which nothing greater can be conceived," which informs debates in ontology alongside thinkers like René Descartes, Gottfried Wilhelm Leibniz, Immanuel Kant, David Hume, Bertrand Russell, G.E. Moore, Alvin Plantinga, Richard Swinburne, Antony Flew, Elizabeth Anscombe, Peter Geach, Richard M. Gale, Nicholas Wolterstorff, William Lane Craig, John Hick, J. L. Mackie. Themes include necessary being versus contingent being as discussed by Aristotle, Plato, Plotinus, Porphyry, Avicenna, Averroes, Maimonides, Saadia Gaon, Thomas Aquinas', Leibnizian principles, Modal logic concerns later formalized by C. I. Lewis, Saul Kripke, Alonzo Church, Kurt Gödel. Anselm treats attributes such as omnipotence, omniscience, and goodness in dialogue with patristic authorities like Augustine, Basil of Caesarea, John Chrysostom, and with scholastic method that anticipates treatments by Peter Lombard and William of Ockham.

Reception and Influence

The text generated immediate medieval responses from contemporaries and successors, provoking commentary from figures such as Eadmer of Canterbury, Lanfranc, William of Malmesbury, Bernard of Clairvaux, Peter Abelard, Hugh of Saint Victor. In the High Middle Ages it shaped curricula at University of Paris, University of Oxford, University of Bologna, and influenced scholastic masters like Thomas Aquinas, Boniface VIII, Robert Grosseteste, John Duns Scotus, Peter Lombard, Albertus Magnus. In the early modern period it was reengaged by philosophers including Descartes, Leibniz, Spinoza, Locke, Hume, Kant, leading to polemics involving David Hume's Treatise, Immanuel Kant's Critique of Pure Reason, G. W. Leibniz's Monadology. Nineteenth- and twentieth-century responses featured critiques and defenses by Bertrand Russell, G. E. Moore, Antony Flew, Alvin Plantinga, G. H. von Wright, Richard Swinburne. The argument also appears in theological dialogues involving John Calvin, Martin Luther, Karl Barth, Friedrich Schleiermacher.

Modern Scholarship and Interpretations

Contemporary scholarship engages philological, philosophical, and theological angles with contributions from Etienne Gilson, Charles Julian, Knut Wicksell, Norman Kretzmann, G.R. Evans, Martin L. Warnke, Brian Davies, M. A. Stewart, G. R. Evans', Thomas Williams, John Marenbon, G. J. P. J. Boudry, Alastair McKinnon, David Knowles, Marjorie O'Rourke Boyle, James F. Ross, Victor Cousin, Paul Helm, Michael Rea, J.P. Moreland, Eleonore Stump, Peter van Inwagen, Sandro Magister, Brian Leftow. Methods include analytic reconstructions, historical-contextual readings, and logical formalizations using modal logics by Kripke, von Wright, C. A. J. Coady. Debates continue over the ontological argument's cogency, its patristic antecedents tracing to Augustine and Anselm's predecessors, and its reception in modern analytic philosophy and continental theology.
