which for example are concerned with a person's being armed or clothed. Lastly comes κεῖσθαι or position, which means to be in a certain position, such for instance as being warm, standing or angry. Of these categories the first four concern bases, the remainder concern only certain topics for argument.
Others make the number of categories to be nine. Person, involving questions concerning the mind, body or external circumstances, which clearly has reference to the means by which we establish conjecture or quality. Time, or χρόνος, from which we get questions such as whether a child is born a slave, if his mother is delivered of him while assigned [*](addicti were not technically servi, though in a virtual condition of servitude, being the bondsmen of their creditors till their debt was paid. ) to her creditors. Place, from which we get such disputes as to whether it is permissible to kill a tyrant in a temple, or whether one who has hidden himself at home can be regarded as an exile.
Then comes time in another sense, called καιρός by the Greeks, by which they refer to a period of time, such as summer or winter;
Cause, under which heading come a large number of disputes, whenever a fact is not denied, but the defence pleads that the act was just and reasonable. τρόπος or manner, which is involved when a thing is said to have been done in one way when it might have been done in another: under this category come cases of such as that of the adulterer who is scourged with thongs or starved to death. [*]( An adulterer caught flagrante delicto might be killed by the husband or beaten. But to starve him to death in cold blood would be illegal. ) Opportunity for action, the meaning of which is too obvious to need explanation or illustration: the Greeks however call it ἔργων ἀφορμαί
These authorities like Aristotle hold that no question can arise which does not come under one of these heads. Some subtract two of them, namely number and opportunity, and substitute for what I have called action, things, or in Greek πράγματα. I have thought it sufficient to notice these doctrines, for fear someone might complain of their omission. Still I do not consider that bases are sufficiently determined by these categories, nor that the latter cover every possible kind of topic, as will be clear to any that read carefully what I have to say on both points. For there will be found to be many topics that are not covered by these categories.
I find it stated in many authors that some rhetoricians only recognise one kind of basis, the con-
Nor does it matter whether one recognises only one kind of basis or none at all, if all causes are of the same nature. Coniectura is derived from conicere
to throw together,because it implies the concentration of the reason on the truth. For this reason interpreters of dreams and all other phenomena are called coniectores
conjecturers.But the conjectural basis has received more names than one, as will appear in the sequel.
Some have recognised only two bases. Archedemus [*](Fr. 11, Arnim.) for instance admits only the conjectural and definitive and refuses to admit the qualitative, since he held that questions of quality take the form of
What is unfair? what is unjust? what is disobedience?which he terms questions about identity and difference. [*](i.e. the question may be stated Does it conform to our conception of injustice or is it something different? Questions of quality are regarded as questions of definition. )
A different view was held by those who likewise only admitted two bases, but made them the negative and juridical. The negative basis is identical with that which we call the conjectural, to which some give the name of negative absolutely, others only in part, these latter holding that conjecture is employed by the accuser, denial only by the accused.
The juridical is that known in Greek as δικαιολογικός But just as Archedemus would not recognise the qualitative basis, so these reject the definitive which they include in the juridical, holding
