Anecdotes
As an adolescent, Anselm is said to have dreamed of climbing a mountain to enter the palace of God: when he awoke, he was convinced of his religious vocation. Yet his father **Gundulf** long opposed his becoming a monk.
After his mother's death, his relationship with his father became so unbearable that Anselm left his native **Piedmont** to cross the Alps. After three years of wandering through **Burgundy** and **France**, he joined the abbey of **Bec** in Normandy, drawn by the reputation of his teacher **Lanfranc**.
Anselm twice refused the office of Archbishop of Canterbury, which was forced upon him almost against his will in **1093**: it is said that his fingers had to be pried open to slip the bishop's crosier into his hand while he protested.
His quarrels with the kings **William Rufus** and then **Henry I** of England, over the power to appoint bishops (the Investiture Controversy), forced him into exile on two occasions. He used the time to travel as far as Rome and to take part in councils.
Anselm said he preferred to seek God through reason rather than through authority alone: his motto “faith seeking understanding” (*fides quaerens intellectum*) sums up his whole method.
