Likewise: It has been said: let us not resist the evil man, let not the vengeance delight us which feeds the mind on others' ill, let us not neglect the reproofs of men.
Idem, to Marcella: If that earthly commonwealth of thine keep to the teachings of Christ, even wars will not be waged without goodwill, for with pitying heart even wars if possible will be waged by the good, so that the lusts of desire may be subdued and those faults destroyed which ought under just rule to be either rooted out or chastised. For if Christian training condemned all wars, this should rather be the advice given in the gospel for their safety to the soldiers who ask for it, namely to throw aside their arms and retire altogether from the field. But this is the word spoken to them: Do violence to no man, neither accuse any falsely; and be content with your wages.
He warns them that the wages that belong to them should satisfy them, but he by no means forbids them to take the field.
Idem, to his comrade Boniface: "I will give thee and thine a useful counsel: Take arms in thy hands; let prayer strike the ears of the creator; because in battle the heavens are opened, God looks forth and awards the victory to the side he sees to be the righteous one."
Idem: The wars to be waged we undertake either at the command of God or under some lawful rule. Else John when the soldiers to be baptized came to him saying, "And what shall we do?" would make answer to them: "Cast aside your arms, leave the service; smite no man; ruin no man."
But because he knew that they did these things because they were in the service, that they were not slayers of men, but servants of the law; and not avengers of their own injuries, but guardians of the public safety, his answer to them was: "Do violence to no man," etc.
Isidore, Etymologiae, Bk. XVIII, ch. iii: A righteous war is one waged according to orders, to recover property or drive back the enemy.
Pope Nicholas to the questions of the Bulgarians: If there is no urgent need, not only in Lent but at all times, men should abstain from battles. If however there is an unavoidable and urgent occasion, and it is not Lent, beyond all doubt preparations for wars should be sparingly made in one's own defence or in that of one's country or the laws of one's fathers; lest forsooth this word be said: A man if he has an attack to make, does not carefully take counsel beforehand for his own safety and that of others, nor does he guard against injury to holy religion.[9]
This example shows the scholastic method in its earliest form,—the statement of the thesis, followed by the simple citation of authorities, pro and con. Later writers added the conclusion which they wished to support, or at least indicated it in the statement of the thesis. This, of course, robbed the method of much of its stimulus to independent thinking. Other modifications also appeared. See the examples on pages 58 ff., 121 ff. The point to be noted here is that in the "Yes and No" Abelard struck out definitely the method which was followed for centuries in a large part of university instruction. How great a part it played can be understood only by an extended study of university history. A brief discussion of the subject is given on pages 35-37. The stimulating way in which Abelard used it was potent in drawing students to Paris. Among those who came to hear him was John of Salisbury.
