Consequently Aristotle in the second book of his Rhetoric has made a careful examination of all that commonly happens to things and persons, and what things and persons are naturally adverse or friendly to other things or persons, as for instance, what is the natural result of wealth or ambition or superstition, what meets with the approval of good men, what is the object of a soldier's or a farmer's desires, and by what means everything is sought or shunned.

For my part I do not propose to pursue this subject. It is not merely a long, but an impossible or rather an infinite task; moreover it is within the compass of the common understanding of mankind. If, however, anyone wishes to pursue the subject, I have indicated where he may apply.

But all credibility, and it is with credibility that the great majority of arguments are concerned, turns on questions such as the following: whether it is credible that a father has been killed by his son, or that a father has committed incest with his daughter, or to take questions of an opposite character, whether it is credible that a stepmother has poisoned her stepchild, or that a man of luxurious life has committed adultery; or again whether a crime has been openly committed, or false evidence given for a small bribe, since each of these crimes is the result of a special cast of character as a rule, though not always; if it were

always so, there would be no room for doubt, and no argument.

Let us now turn to consider the

places
of arguments, although some hold that they are identical with the topics which I have already discussed above. [*](In previous chapter.) But I do not use this term in its usual acceptance, namely, commonplaces [*](See ii. iv. 22, v. xii. 6 and xiii. 57.) directed against luxury, adultery, and the like, but in the sense of the secret places where arguments reside, and from which they must be drawn forth.

For just as all kinds of produce are not provided by every country, and as you will not succeed in finding a particular bird or beast, if you are ignorant of the localities where it has its usual haunts or birthplace, as even the various kinds of fish flourish in different surroundings, some preferring a smooth and others a rocky bottom, and are found on different shores and in divers regions (you will for instance never catch a sturgeon or wrasse in Italian waters), so not every kind of argument can be derived from every circumstance, and consequently our search requires discrimination.
