Some argument schemes are designated by Latin labels, S. A/ab —; Ad —; Ex —. This entry lists the labels using the Latin preposition ad. In classical Latin, the preposition ad is constructed with the accusative and introduces a goal complement; the phrase “argument ad hominem” reads “argument addressing the person”.
According to Hamblin, the oldest scheme in this grouping is ad hominem, which appears in the Latin translations of Aristotle; this naming method was popularized by Locke ([1690]) and by Bentham ([1824]), and most of these terms seem to be nineteenth or twentieth century creations (Hamblin 1970, p. 41; p. 161-162).

2. Characteristics of the “ad + N” family
2.1 A productive pattern
There are many more “ad +N” arguments than there are “a / ab + N” arguments. Only the “ad +N” construction is still productive; the pattern is popular and mocked (ad bananum argument).
2.2 Origin of the labels
Some of these names have been defined and used by Locke and Bentham, S. Collections (III).
Locke has defined the arguments:
ad hominem ad judicium
ad ignorantiam ad verecundiam
Bentham has defined the arguments:
| ad amicitiam ad ignorantiam ad imaginationem ad invidiam |
ad judicium ad metum ad odium ad quietem |
ad socordiam ad superbiam ad superstitionem ad verecundiam |
2.3 Semantic subsets of “ad + N” arguments
These arguments refer to very different strategies. Nonetheless, some groupings can be proposed according to their semantic content.
(i) Arguments bound to affects, emotions, often via positive interest (rewards) or negative results (threats):
| ad amicitiam ad captandum vulgus ad invidiam ad ludicrum ad metum (ad carcerem, ad baculum, ad fulmen, ad crumenam) |
ad misericordiam ad novitatem ad numerum ad passionem ad odium ad quietem |
ad personam ad populum ad superbiam ad verecundiam |
(ii) Arguments involving a subjective system of beliefs, not universal, questionable:
| ad consequentiam ad fidem ad hominem |
ad ignorantiam ad imaginationem ad incommodum |
ad socordiam ad superstitionem ad vertiginem |
Categories (i) and (ii) list arguments often considered as misleading, insofar as they express the subjectivity of the speaker. In other words, they are related to the ethotic and pathemic components
(iii) Arguments dealing with the substance of the issue (contrasting with the subjective series (i) and (ii))
