Abstract

It has usually been assumed that monadic value notions can be defined in terms of dyadic value notions, whereas definitions in the opposite direction are not possible. In this paper, inspired by van Benthem’s work, it is shown that the latter direction is feasible with a method in which shifts in context have a crucial role. But although dyadic preference orderings can be defined from context-indexed monadic notions, the monadic notions cannot be regained from the preference relation that they gave rise to. Two formal languages are proposed in which reasoning about context can be represented in a fairly general way. One of these is a modal language much inspired by van Benthem’s work. Throughout the paper the focus is on relationships among the value notions “good”, “bad”, and “better”. Other interpretations like “tall” and “taller” are equally natural. It is hoped that the results of this paper can be relevant for the analysis of natural language comparatives and of vague predicates in general.

Notes

  1. 1.

    Here we follow Graham’s numbering of the Canons. He made a hybrid text from Xiaoqu and part of Daqu under the title “Names and Objects” (abbreviated “NO”) We also use his translations.

  2. 2.

    Halldén [11, p. 28], von Wright [22, pp. 24–25, 40, 60]. For further references see Hansson [13, pp. 89–90].

  3. 3.

    In the logic of exclusionary preferences we use the letters \(x, y, z \dots \) to denote the objects of evaluation. When the objects of evaluation have sentential structure we use the letters \(p, q, r\dots \).

  4. 4.

    To simplify the notation, we contract series of two-place predicate expressions, thus writing \(x \! \ge \! y \! \ge \! z\) for \( x \! \ge \! y \ \& \ y \! \ge \! z\), and similarly \(x \! > \! y \! \approx \! z\) for \( x \! > \! y \ \& \ y \! \approx \! z\), etc.

  5. 5.

    See Mitchell [18, pp. 103–105], Halldén [11, p. 109], von Wright [22, p. 34] and [23, p. 162], and Åqvist [3].

  6. 6.

    Other variants of the same basic approach replace Chisholm and Sosa’s indifferent sentences by tautologies [8, p. 37], or contradictions [23, p. 164]. This approach gives rise to the following formal definitions:

    \(G_{\scriptstyle \top }p \leftrightarrow p \! > {\scriptstyle \top }\) (tautology-related good)

    \(B_{\scriptstyle \top }p \leftrightarrow {\scriptstyle \top }> \!p\) (tautology-related bad)

    \(G_{\scriptstyle \perp }p \leftrightarrow p \! > {\scriptstyle \perp }\) (contradiction-related good)

    \(B_{\scriptstyle \perp }p \leftrightarrow {\scriptstyle \perp }> \!p\) (contradiction-related bad)

    However, the interpretation of what it means for something to be better or worse than a tautology or (in particular) a contradiction is quite problematic.

  7. 7.

    An even weaker property than reflexivity, namely ancestral reflexivity (\(p \! \ge \! \! \! ^\star p\)), is sufficient for this result.

  8. 8.

    For an attempt to deal with some such differences, see Hansson [14]. See also Stalnaker [20].

  9. 9.

    This also applies to many other adjectives, hence we would say that \(x\) is longer than \(y\) if and only if \(y\) is shorter than \(x\).

  10. 10.

    The term “polarization” indicates that if \(x\) and \(y\) differ in terms of goodness and badness in the context \(\{x,y\}\), then they are at opposite sides of the value scale, i.e. one of them is good and the other is bad.

  11. 11.

    The subformula \({\large <} up {\large >}\,{\large <} dn {\large >}\) is used as a means to reach (any) other reachable context while remaining in the same actual state. Its plausibility for this purpose depends on conditions that we will not discuss further here, namely (i) \( {\large <} up {\large >}\,{\large <} up {\large >} \phi \leftrightarrow {\large <} up {\large >} \phi \), (ii) \( {\large <} dn {\large >}\,{\large <} dn {\large >} \phi \leftrightarrow {\large <} dn {\large >} \phi \), and (the somewhat more questionable) \( {\large <} up {\large >}\,{\large <} dn {\large >} \phi \leftrightarrow {\large <} dn {\large >}\,{\large <} up {\large >} \phi \).
