We now turn to the use of Maxims, in order to see upon what subjects and occasions, and for what kind of speaker, they will appropriately form part of a speech. This will appear most clearly when we have defined a maxim. It is a statement; not a particular fact, such as the character of lphicrates, but of a general kind; nor is it about any and every subject--e.g. 'straight is the contrary of curved' is not a maxim--but only about questions of practical conduct, courses of conduct to be chosen or avoided. Now an Enthymeme is a syllogism dealing with such practical subjects. It is therefore roughly true that the premisses or conclusions of Enthymemes, considered apart from the rest of the argument, are Maxims: e.g.
Never should any man whose wits are sound Have his sons taught more wisdom than their fellows.
Here we have a Maxim; add the reason or explanation, and the whole thing is an Enthymeme; thus-It makes them idle; and therewith they earn Ill-will and jealousy throughout the city.
Again, There is no man in all things prosperous, and There is no man among us all is free, are maxims; but the latter, taken with what follows it, is an Enthymeme-For all are slaves of money or of chance.
From this definition of a maxim it follows that there are four kinds of maxims. In the first Place, the maxim may or may not have a supplement. Proof is needed where the statement is paradoxical or disputable; no supplement is wanted where the statement contains nothing paradoxical, either because the view expressed is already a known truth, e.g.
Chiefest of blessings is health for a man, as it seemeth to me, this being the general opinion: or because, as soon as the view is stated, it is clear at a glance, e.g.
No love is true save that which loves for ever.
Of the Maxims that do have a supplement attached, some are part of an Enthymeme, e.g.
Never should any man whose wits are sound, &c.
Others have the essential character of Enthymemes, but are not stated as parts of Enthymemes; these latter are reckoned the best; they are those in which the reason for the view expressed is simply implied, e.g.
O mortal man, nurse not immortal wrath.
To say 'it is not right to nurse immortal wrath' is a maxim; the added words 'mortal man' give the reason. Similarly, with the words Mortal creatures ought to cherish mortal, not immortal thoughts.
What has been said has shown us how many kinds of Maxims there are, and to what subjects the various kinds are appropriate. They must not be given without supplement if they express disputed or paradoxical views: we must, in that case, either put the supplement first and make a maxim of the conclusion, e.g. you might say, 'For my part, since both unpopularity and idleness are undesirable, I hold that it is better not to be educated'; or you may say this first, and then add the previous clause. Where a statement, without being paradoxical, is not obviously true, the reason should be added as concisely as possible. In such cases both laconic and enigmatic sayings are suitable: thus one might say what Stesichorus said to the Locrians, 'Insolence is better avoided, lest the cicalas chirp on the ground'.
