2019, HUME. LOGICAL INDUCTION, AND LEGAL REASONING

“When we have found a resemblance among several objects, we apply the same name to all of them, whatever differences we may observe in the degrees of their quantity and quality, and whatever other differences may appear among them.” (David Hume, A Treatise on Human Understanding , Book 1 Part 1 Sec VII para. 7) David Hume's expository use of “we” is a commonly accepted discursive practice. But its use can leave out the possibility of disagreement over the purpose and consequences of a disputed resemblance. The expository “we” deploys an ideal observer of a paradigmatic situation; it obscures whether, in actual life, the general statement of resemblance applies to all possible communities of speakers. It obscures the social dimension of establishing similarity. The issue of similarity doesn’t arise unless there is a practical uncertainty regarding the resemblance in question. Such practical uncertainty arises constantly in the operation of legal adjudication. Naming is another crucial constitutive element in logical theory. What if the reach of application by a particular “name” is disputed by opposing interests within the same linguistic community? Parties to legal disputes may seek to gain coverage of a legal term (“liberty,” “equality,” even “murder”) for their own interests, and to exclude other interests. This can be seen in minor disputes, or in major ones like the extension of the constitutional right of free expression to political campaign donations (hence the extension of “liberty”), of murder or homicide to doctor-assisted suicide, or of marriage to same-gender partners (implicating the extension of “equality”). Precisely what induction means in legal reasoning is the subject of this paper.
