2.7
There is a different type of question where the dispute is concerned with the term to be applied, which depends on the letter of the law: it is a form of question which can only arise in the courts from the actual words on which the dispute turns. Take as examples the questions, whether suicide is a form of homicide, or whether the man who forces a tyrant to kill himself can be considered a tyrannicide, or whether magical incantations are equivalent to the crime of poisoning. In all these cases there is no doubt about the facts, for it is well known that there is a difference between killing oneself and killing another, between slaying a tyrant and forcing him to suicide, between employing incantations and administering a deadly draught, but we enquire whether we are justified in calling them by the same name.

Though I hardly like to differ from Cicero, cp. III. vi. 31. who follows many authorities in saying that definition is concerned with identity and difference (since he who denies the applicability of one term must always produce another term which he regards as preferable), for my own part I consider that definition falls into three types, which I may perhaps call species.
