Abélard's works were collected by Cousin, and published in three 4to volumes (Paris, 1836, 1849, 1859). They include, besides the correspondence with Héloïse, and a number of sermons, hymns, answers to questions, etc., written for her, the following:--(1) 'Sic et Non,' a collection of (often contradictory) statements of the Fathers concerning the chief dogmas of religion, (2) 'Dialectic,' (3) 'On Genera and Species,' (4) Glosses to Porphyry's 'Introduction,' Aristotle's 'Categories and Interpretation,' and Boethius's 'Topics,' (5) 'Introduction to Theology,' (6) 'Christian Theology,' (7) 'Commentary on the Epistle to the Romans,' (9) 'Abstract of Christian Theology,' (10) 'Ethics, or Know Thyself,' (11) 'Dialogue between a Philosopher, a Jew, and a Christian,' (12) 'On the Intellects,' (12) 'On the Hexameron,' with a few short and unimportant fragments and tracts. None of Abélard's numerous poems in the vernacular, in which he celebrated his love for Héloïse, which he sang ravishingly (for he was a famous singer), and which at once became widely popular, seem to have come down to us; but we have a somewhat lengthy poem, of considerable merit (though of doubtful authenticity), addressed to his son Astralabius, who grew to manhood, became a cleric, and died, it seems, as abbot of Hauterive in Switzerland, in 1162. Of Abélard's philosophy, little need be added to what has been already said. It is, on the whole, the philosophy of the Middle Age, with this difference: that he insists upon making theology rational, and thus may truly be called the founder of modern rationalism, and the initiator of the struggle against the tyrannic authority of blind faith. To have been so is his crowning merit, and is one that can hardly be overestimated. At the same time it must be borne in mind that he was a loyal son of the Church, and never dreamed of opposing or undermining her. His greatest originality is in 'Ethics,' in which, by placing the essence of morality in the intent and not in the action, he anticipated Kant and much modern speculation. Here he did admirable work. Abélard founded no school, strictly speaking; nevertheless, he determined the method and aim of Scholasticism, and exercised a boundless influence, which is not dead. Descartes and Kant are his children. Among his immediate disciples were a pope, twenty-nine cardinals, and more than fifty bishops. His two greatest pupils were Peter the Lombard, bishop of Paris, and author of the 'Sentences,' the theological text-book of the schools for hundreds of years; and Arnold of Brescia, one of the noblest champions of human liberty, though condemned and banished by the second Council of the Lateran. The best biography of Abélard is that by Charles de Rémusat (2 vols., 8vo, Paris, 1845). See also, in English, Wight's 'Abelard and Eloise' (New York, 1853).
