ANSELM, Archbishop of Canterbury, was born in 1033, at or near Aosta, in Piedmont. His family was accounted noble, and was possessed of considerable property. Gundulph, his father, was by birth a Lombard, and seems to have been a man of harsh and violent temper ; his mother, Ermenberga, was a prudent and virtuous woman, from whose careful religious training the young Anselm derived much benefit. At the early age of fifteen he desired to devote himself to the service of God by entering a convent, but he could not obtain his father's consent. Disappoint ment brought on an illness, on his recovery from which he seems for a time to have given up his studies, and to have plunged into the gay life of the world. During this time his mother died, and his father's harshness became unbearable. He left home, and with only one attendant crossed the Alps, and wandered through Burgundy and France. Attracted by the fame of his countryman, Lanfranc, then prior of Bee, he entered Normandy, and, after spending some time at Avranches, settled at the monastery of Bec. There, at the age of twenty-seven, he became a monk ; three years later, when Lanfranc was promoted to the abbacy of Caen, he was elected prior. This office he held for fifteen years, and then, in 1078, on the death of Herluin, the warrior-monk who had founded the monastery, he was made abbot. Under his rule Bee became the first seat of learning in Europe, a result due not more to his intellectual powers than to the great moral influence of his noble character, and his loving, kindly discipline. It was during these quiet years at Bec that Anselm wrote his first philosophical and religious works, the dialogues on Truth and Freewill, and the two celebrated treatises, the Monologion and Proslogion. Meanwhile the convent had been growing in wealth, as well as in reputation, and, among other properties, had acquired considerable possessions in England. Anselm paid frequent visits to that country in connection with the convent lands, and by his mildness of temper and unswerving rectitude, so endeared himself to the English that he was looked upon and desired as the natural successor to Lanfranc, then archbishop of Can-terbury. But on the death of that great man, the rul-ing sovereign, William Bufus, seized the possessions and revenues of the see, and made no new appointment. About four years after, in 1092, on the invitation of Hugh, earl of Chester, Anselm, with some reluctance, for he feared to be made archbishop, crossed to England. He was detained by business for nearly four months, and when about to return, was refused permission by the king. In the following year William fell ill, and thought his death was at hand. Eager to make atonement for his sin with regard to the archbishopric, he nominated Anselm to the vacant see, and, after a great struggle, compelled him to accept the pastoral staff of office. After obtaining dis-pensation from his duties in Normandy, Anselm was con-secrated in 1093. He demanded of the king, as the con-ditions of his retaining office, that he should give up all the possessions of the see, accept his spiritual counsel, and acknowledge Urban as Pope, in opposition to the anti-pope, Clement. He only obtained a partial consent to the first of these, and the last involved him in a serious difficulty with the king. It was a rule of the church that the con-secration of metropolitans could not be completed without their receiving from the hands of the Pope the Pallium, or robe. Anselm, accordingly, insisted that he must proceed to Rome to receive the pall. But William would not per-mit this ; he had not acknowledged Urban, and he main-tained his right to prevent any Pope being acknowledged by an English subject without his permission. A great, council of churchmen and nobles, held to settle the matter, advised Anselm to submit to the king, but failed to over-come his mild and patient firmness. The matter was postponed, and William meanwhile privately sent messengers to Rome, who acknowledged Urban, and prevailed OE him to send a legate to the king, bearing the archiépiscopal pall. A partial reconciliation was then effected, and the matter of the pall was compromised. It was not given by the king, but was laid on the altar at Canterbury, whence Anselm took it. Little more than a year after, fresh trouble arose with the king, and Anselm resolved to pro-ceed to Rome and seek the counsel of his spiritual father.
With great difficulty he oDtained a reluctant permission to leave, and in October 1097 he set out for Rome. William immediately seized on the revenues of the see, and retained them to his death Anselm was received with high honour by Urban, and at a great council held at Bari, he was put forward to defend the Latin doctrine of the Holy Ghost against the objections of the Greek Church But Urban was too politic to embroil himself with the king of Eng-land, and Anselm found that he could obtain no substantial result. He withdrew from Borne, and spent some time at the little village of Schlavia. Here he finished his treatise on the atonement, Cur Dens homo, and then retired to Lyons. In 1100 William was killed, and Henry, his suc-cessor, at once recalled Anselm. But Henry demanded that he should again receive from him in person investi-ture in his office of archbishop, thus making the dignity entirely dependent on the royal authority. Now, the Papal rule in the matter was plain ; all homage and lay investi-ture were strictly prohibited. Anselm represented this to the king; but Henry would not relinquish a privilege possessed by his predecessors, and proposed that the matter should be laid before the Holy See. The answer of the Pope reaffirmed the law as to investiture. A second embassy was sent, with a similar result. Henry, however, remained firm, and at last, in 1103, Anselm and an envoy from the king set out for Bome. The Pope, Paschal, reaffirmed strongly the rule of investiture, and passed sentence of excommunication against all who had infringed the law, except Henry. Prac-tically this left matters as they were, and Anselm, who had received a message forbidding him to return to England, unless on the king's terms, withdrew to Lyons, where he waited to see if Paschal would not take stronger measures. At last, in 1105, he resolved himself to excommunicate Henry. His intention was made known to the king through his sister, and it seriously alarmed him, for it was a critical period in his affairs. A meeting was arranged, and a reconciliation between them effected. In 1106 Anselm crossed to England, with power from the Pope to remove the sentence of excommunication from the illegally invested churchmen. In 1107 the long dispute as to in-vestiture was finally ended by the king resigning his formal rights. The remaining two years of Anselm's life were spent in the duties of his archbishopric. He died 21st April 1109. His canonization appears to have taken place in 1494.
Anselm may, with some justice, be considered the first scholastic philosopher and theologian. His only great predecessor, Scotus Erigena, had more of the speculative and mystical element than is consistent with a schoolman; but in Anselm are found that recognition of the relation of reason to revealed truth, and that attempt to elaborate a rational system of faith, which form the special character-istics of scholastic thought. His constant endeavour is to render the contents of the Christian consciousness clear to reason, and to develop the intelligible truths interwoven with the Christian belief. The necessary preliminary for this is the possession of the Christian consciousness. " He who does not believe will not experience; and he who has not experienced will not understand." That faith must precede knowledge is reiterated by him. " Neque enim qusero intelligere ut credam, sed credo ut intelligam. Nam et hoc credo, quia, nisi credidero, non intelligam." " Chris-tianus per fidem debet ad intellectum proficere, non per intellectum ad fidem accedere." " Rectus ordo exigit, ut profunda Christianas fidei credamus, priusquam ea praesum-amus ratione discutere." But after the faith is held fast, the attempt must be made to demonstrate by reason the truth of what we believe. It is wrong not to do so. " Negligentias mihi esse videtrr, si, postquam confirmati sumus in fide, non studemus quod credimus, intelligere."
To such an extent does he carry this demand for rational explanation that, at times, it seems as if he claimed for unassisted intelligence the power of penetrating even to the mysteries of the Christian faith. On the whole, however, the qualified statement is his real view; merely rational proofs are always, he affirms, to be tested by Scripture. (Cur Deus homo, i. 2 and 38; De Fide Trin. 2.)
The groundwork of his theory of knowledge is contained in the tract Be Veritate, in which, from the consideration of truth as in knowledge, in willing, and in things, he rises to the affirmation of an absolute truth, in which all other truth participates. This absolute truth is God himself, who is therefore the ultimate ground or principle both of things and of thought. The notion of God comes thus into the foreground of the system; before all things it is necessary that it should be made clear to reason, that it should be demonstrated to have real existence. This demonstration is the substance of the Monologion and Proslogion. In the first of these the proof rests on the ordinary grounds of realism, and coincides to some extent with the earlier theory of Augustine, though it is carried out with singular boldness and fulness. Things, he says, are called good in a variety of ways and degrees; this would be impossible if there were not some absolute standard, some good in itself, in which all relative goods participate. Similarly with such predicates as great, just; they involve a certain greatness and justice. The very existence of things is impossible without some one Being, by whom they are. This absolute Being, this goodness, justice, greatness, is God. Anselm was not thoroughly satisfied with this reasoning ; it started from a posteriori grounds, and contained several converging lines of proof. He desired to have some one short demonstration. Such a demonstration he presented in the Proslogion; it is his celebrated ontological proof. God is that being than whom none greater can be conceived. Now, if that than which nothing greater can be conceived existed only in the intellect, it would not be the absolutely greatest, for we could add to it existence in reality. It follows, then, that the being than whom nothing greater can be conceived, i.e., God, necessarily has real existence. This proof has rarely seemed satisfactory. It was opposed at the time by the monk Gaunilo, in his Liber pro Insipiente, on the ground that we cannot pass from idea to reality. The same criticism is made by several of the later schoolmen, among others by Aquinas, and is in substance what Kant advances against all ontological proof. Anselm replied to the objec-tions of Gaunilo in his Liber Apologeticus. The existence of God being thus held proved, he proceeds to state the rational grounds of the Christian doctrines of creation and of the Trinity. With reference to this last, he says we cannot know God from himself, but only after the analogy of his creatures; and the special analogy used is the self-consciousness of man, its peculiar double nature, with the necessary elements, memory and intelligence, representing the relation of the Father and the Son. The mutual love of these two, proceeding from the relation they hold to one another, symbolises the Holy Spirit. The further theo-logical doctrines of man, original sin, free will, are de-veloped, partly in the Monologion, partly in special treatises. Finally, in his greatest work, Cur Deus homo, he undertakes to make plain, even to infidels, the rational necessity of the Christian mystery of the atonement. The theory rests on three positions: that satisfaction is necessary on account of God's honour and justice; that such satisfaction can be given only by the peculiar person-ality of the God-man; that such satisfaction is really given by the voluntary death of this infinitely valuable person. The demonstration is, in brief, this. All the actions of men are due to the furtherance of God's glory; if, then, there bosin, i.e., if God's honour be wounded, man of himself can give no satisfaction. But the justice of God demands satisfaction ; and as an insult to infinite honour is in itself infinite, the satisfaction must be infinite, i.e., it must out-weigh all that is not God. Such a penalty can only be paid by God himself, and, as a penalty for man, must be paid under the form of man. Satisfaction is only possible through the God-man. Now this God-man, as sinless, is exempt from the punishment of sin ; His passion is there-fore voluntary, not given as due. The merit of it is there-fore infinite ; God's justice is thus appeased, and His mercy may extend to man. This theory has exercised immense influence on the form of church doctrine. It is certainly an advance on the older patristic theory, in so far as it substitutes for a contest between God and Satan, a contest between the goodness and justice of God ; but it puts the whole relation on a merely legal footing, gives it no ethical bearing, and neglects altogether the conscious-ness of the individual to be redeemed. In this respect it contrasts unfavourably with the later theory of Abelard.
Anselm's speculations did not receive, in the Middle Ages, the respect and attention justly their due. This was perhaps owing to their unsystematic character, for they are generally tracts or dialogues on detached questions, not elaborate treatises like the great works of Albert, Aquinas, and Duns Scotus. They have, however, a freshness and philosophical vigour, which more than makes up for their want of system, and which raises them far above the level of most scholastic writings.
A full account of Anselm's life is given by Eadmer, Vita Anselmi. His works have been frequently published; the best editions are by Gerberon (containing the life, by Eadmer), Paris, 1675, 2nd ed. 1721; and in Migne, Patrologiae Cursus Completus, vol. civ.
The Cur Deus homo has been frequently published in a separate form. The Monologion and Proslogion have been translated, with notes, by Bouchitté, Le Rationalisme Chrétien, Paris, 1842. In addition to the copious notices in general histories of theology and philosophy, the following works may be referred to: Möhler, Anselm, translated into English, 1842; Franck, Anselm von Canterbury, 1842; Hasse, Anselm von Canterbury, I.
