The things which beget concord are those which are related to justice, integrity, and honor; for besides that which is unjust and injurious, men take ill also anything which is esteemed base, or that any one should despise the received customs of the State. But in order to win love, those things are chiefly necessary which have reference to religion and piety.

Concord, moreover, is often produced by fear, but it is without good faith. It is to be observed, too, that fear arises from impotence of mind, and therefore is of no service to reason; nor is pity, although it seems to present an appearance of piety.

Men also are conquered by liberality, especially those who have not the means wherewith to procure what is necessary for the support of life. But to assist every one who is needy far surpasses the strength or profit of a private person, for the wealth of a private person is altogether insufficient to supply such wants. Besides, the power of any one man is too limited for him to be able to unite every one with himself in friendship. The care, therefore, of the poor is incumbent on the whole of society and concerns only the general profit.
XVIII
In the receipt of benefits and in returning thanks, care altogether different must be taken.

The love of a harlot, that is to say, the lust of sexual intercourse, which arises from mere external form, and absolutely all love which recognizes any other cause than the freedom of the mind, easily passes into hatred, unless, which is worse, it becomes a species of delirium, and thereby discord is cherished rather than concord.
