acting. Which being thus defin'd, he that per∣swades must shew those things, to which he ex∣horts, to be either just, or legal, profitable, ho∣nest, delightful or easily practicable. If not, he must make 'em appear to be possible, if he ex∣horts to difficult things, and make it out that they are necessary. He that disswades must make the contrary appear; as that they are unjust, ille∣gal, useless, unpleasing, dishonest, and impossible to be accomplish'd: if not, that they are difficult, troublesome, and not necessary. For all actions participate of these things, so that he who has neither of these Propositions, wants Arguments.
Now I shall endeavour to define every one of these, and to shew, how we may be sufficiently furnish'd with all these for Arguments. There∣fore the unwritten custom of All, or Most, is but just in the definition of what is honest, what infa∣mous; as to honour our Parents, to love our friends, and be greatful to our Benefactors. For such pre∣cepts as these are not Commanded by the written Laws, but by unwritten Custom and the Common Law of nature. These therefore are just things.
The Law is the Common consent of a City, commanding in Writing, how we ought to act in such and such particulars.
Profitable, is the Conservation of present bene∣fits, the acquiring of absent benefits, or the warding off present evils, or the prohibition of threating Inconveniences. This must be divided, as to present Persons, into Body and Soul, and things external. To the Body are profitable Strength, Beauty, Health. To the Soul, Fortitude, Wisdom, Justice. External things are Friends, Mony, Lands. The contrary to which are un∣profitable.
