A second and indispensable virtue was courage. The knight must be brave as well as loyal. Cowardice and knighthood were wholly incompatible things.
Another moral quality was veracity, absolute fidelity to a promise. The pledged word of the true knight was sacrosanct and inviolable.[682]
Still another indispensable trait in the character of the ideal knight was love of justice. The true knight must be just; an unjust knight could not be a true knight any more than an unjust judge can be a true judge.
Again, the knight who would be loyal to the ideal of knighthood must be magnanimous. One of the elements of this virtue is unwillingness to take an unfair advantage of another, especially of an enemy. It was a disgraceful thing for a knight to attack his foe when at a disadvantage, as when disarmed or fallen. He must always meet his enemy in fair and open fight.
Furthermore, the true knight must be courteous. It was as much his duty to be courteous as to be truthful. Now courtesy is not a trait or feeling which inspires lofty action, but one which induces gentleness, kind consideration, and gracious deference toward all alike—rich and poor, high and low.
Lastly, the knight must possess dignity or self-respect. The age of chivalry interpreted this virtue or duty as requiring the knight to stand on his rights as a man. He must not let an injury to himself or to a friend go unpunished. He must resent every insult and return blow for blow. Not to do so argued cowardice and pusillanimity. All this was of course directly opposed to the Christian requirements of humility, meekness, nonresistance, and forgiveness of injuries, and was distinctly a part of the moral code of chivalry which was borrowed from pre-Christian or non-Christian morality.
To these essentially pagan virtues the knight, after the institution of chivalry had been approved and consecrated by the Church, must add all the distinctly Christian virtues, particularly the virtue of right religious belief. Only the true believer could be a true knight.
A striking illustration of the mixture of moralities with which we have to do in the period of chivalry is afforded by the celebrated religious military orders of the Hospitalers and Templars, which were formed just before the Second Crusade, when the enthusiasm for the chivalric ideal was at its height, while that for the ascetic had not yet sensibly abated. The Hospitalers were monks who, to their monastic vows of poverty, chastity, and obedience or humility, added the martial obligations of knighthood; the Templars were knights who to their military vows added those of the monk. Thus in these remarkable orders of knight-monks we see incongruously united the monastic and military ideals, two of the most sharply contrasted conceptions of worthy life that it is possible to find in the whole history of ethical ideals.
Defects of the ideal
The ideal of chivalry had serious defects. First, the military spirit, borrowed from paganism, which the ideal apotheosized, was in absolute opposition to the spirit of Christianity, so that the perfect reconciliation and fusion of the different moral qualities entering into the ideal was impossible.
