Book 7
8.3
The syllogistic basis, then, deduces from the letter of the law that which is uncertain; and since this conclusion is arrived at by reason, the basis is called ratiocinative. See in. vi. 43, 61. It may be subdivided into the following species of question. If it is right to do a thing once, is it right to do it often? Example: A priestess found guilty of unchastity is thrown from the Tarpeian rock and survives. It is demanded that she shall be thrown down again. If the law grants a privilege with reference to one thing, does it grant it with reference to a number? Example: A man kills two tyrants together and claims two rewards.
8.4
If a thing is legal before a certain occurrence, is it legal after it? Example: The ravisher took refuge in flight. His victim married. The ravisher returned and the woman demands to be allowed her choice. i. e. the death of the ravisher, see n. on VII. vii. 3. Is that which is lawful with regard to the whole, lawful with regard to a part? Example: It is forbidden to accept a plough as security. He accepted a ploughshare. Is that which is lawful with regard to a part, lawful with regard to the whole? Example: It is forbidden to export wool from Tarentum: he exported sheep.
