Natural law is that which has not had its origin in the opinions of men, but has been implanted by some innate instinct, like religion, affection, gratitude, revenge, attention to one's superiors, truth. Religion is that which causes men to pay attention to, and to respect with fixed ceremonies, a certain superior nature which men call divine nature. Affection is that feeling under the influence of which kindness and careful attention is paid to those who are united to us by ties of blood, or who are devoted to the service of their country. Gratitude is that feeling in which the recollection of friendship, and of the services which we have received from another, and the inclination to requite those services, is contained. Revenge is that disposition by which violence and injury, and altogether everything which can be any injury to us, is repelled by defending oneself from it, or by avenging it. Attention is that feeling by which men obey when they think those who are eminent for worth or dignity, worthy of some special respect and honour. Truth is that by which those things which are, or which have been previously, or which are about to happen, are spoken of without any alteration.

LIV. Conventional law is a principle which has either derived its origin in a slight degree from nature, and then has been strengthened by habit, like religion; or, if we see any one of those things which we have already mentioned as proceeding from nature strengthened by habit; or, if there is anything to which antiquity has given the force of custom with the approbation of everybody: such as covenants, equity, cases already decided. A covenant is that which is agreed upon between two parties; equity is that which is equally just for every one; a case previously decided is one which has been settled by the authoritative decision of some person or persons entitled to pronounce it.

Legal right is that which is contained in that written form which is delivered to the people to be observed by them.

Fortitude is a deliberate encountering of danger and enduring of labour. Its parts are magnificence, confidence, patience, and perseverance. Magnificence is the consideration and management of important and sublime matters with a certain wide-seeing and splendid determination of mind. Confidence is that feeling by which the mind embarks in great and honourable courses with a sure hope and trust in itself. Patience is a voluntary and sustained endurance, for the sake of what is honourable or advantageous, of difficult and painful labours. Perseverance is a steady and lasting persistence in a well-considered principle.

Temperance is the form and well-regulated dominion of reason over lust and other improper affections of the mind. Its parts are continence, clemency, and modesty. Continence is that by which cupidity is kept down under the superior influence of wisdom. Clemency is that by which the violence of the mind, when causelessly excited to entertain hatred against some one else, is restrained by courtesy. Modesty is that feeling by which honourable shame acquires a valuable and lasting authority. And all these things are to be sought for themselves, even if no advantage is to be acquired by them. And it neither concerns our present purpose to prove this, nor is it agreeable to our object of being concise in laying down our rules.

But the things which are to be avoided for their own sake, are not those only which are the opposites to these; as indolence is to courage, and injustice to justice; but those also which appear to be near to and related to them, but which, in reality, are very far removed from them. As, for instance, diffidence is the opposite to confidence, and is therefore a vice; audacity is not the opposite of confidence, but is near it and akin to it, and, nevertheless, is also a vice. And in this manner there will be found a vice akin to every virtue, and either already known by some particular name—as audacity, which is akin to confidence; pertinacity, which is bordering on perseverance; superstition, which is very near religion,—or in some cases it has no fixed name. And all these things, as being the opposites of what is good, we class among things to be avoided. And enough has now been said respecting that class of honourable things which is sought in every part of it for itself alone.

LV. At present it appears desirable to speak of that in which advantage is combined with honour, and which still we style simply honourable. There are many things, then, which allure us both by their dignity and also by the advantage which may be derived from them: such as glory, dignity, influence, friendship. Glory is the fact of a person's being repeatedly spoken of to his praise; dignity is the honourable authority of a person, combined with attention and honour and worthy respect paid to him. Influence is a great abundance of power or majesty, or of any sort of resource. Friendship is a desire to do service to any one for the sake of the person himself to whom one is attached, combined with a corresponding inclination on his part towards oneself. At present, because we are speaking of civil causes, we add the consideration of advantage to friendship, so that it appears a thing to be sought for the sake of the advantage also: wishing to prevent those men from blaming us who think that we are including every kind of friendship in our definition.

But although there are some people who think that friendship is only to be desired on account of the advantage to be derived from it; some think it is to be desired for itself alone; and some, that it is to be desired both for its own sake and for the sake of the advantage to be derived from it. And which of these statements is the most true, there will be another time for considering. At present it may be laid down, as far as the orator is concerned, that friendship is a thing to be desired on both accounts. But the consideration of the different kinds of friendship, (since they are partly formed on religious considerations, and partly not; and because some friendships are old, and some new; and because some originated in kindness shown by our friends to us, and some in kindness shown by ourselves to them; and because some are more advantageous, and others less,) must have reference partly to the dignity of the causes in which it originates, partly to the occasion when it arises, and also to the services done, the religious motives entertained, and its antiquity.

LVI. But the advantages consist either in the thing itself, or in extraneous circumstances; of which, however, by far the greater portion is referable to personal advantage; as there are some things in the republic which, so to say, refer to the person of the state,—as lands, harbours, money, fleets, sailors, soldiery, allies; by all which things states preserve their safety and their liberty. There are other things also which make a thing more noble looking, and which still are less necessary; as the splendid decorating and enlarging of a city, or an extraordinary amount of wealth, or a great number of friendships and alliances. And the effect of all these things is not merely to make states safe and free from injury, but also noble and powerful. So that there appears to be two divisions of usefulness,—safety and power. Safety is the secure and unimpaired preservation of a sound state. Power is a possession of things suitable to preserving what is one's own, and to acquiring what belongs to another. And in all those things which have been already mentioned, it is proper to consider what is difficult to be done, and what can be done with ease. We call that a thing easy to be done, which can be done without great labour, or expense, or annoyance, or perhaps without any labour, expense, or annoyance at all, and in the shortest possible time. But that we call difficult to be done which, although it requires labour, expense, trouble and time, and has every possible characteristic of difficulty about it, or, at all events, the most numerous and most important ones, still, when these difficulties are encountered, can be completed and brought to an end.

Since, then, we have now discussed what is honourable and what is useful, it remains for us to say a little of those things which we have said are attached to these other things; namely, affection and necessity.
