The paper proposes and defends the following characterization of response dependent property: a property is response-dependent iff there is a response-dependence biconditional for a concept signifying it which holds in virtue of the nature of the property. Finding out whether a property is such is to a large extent a posteriori matter. Finally, colors are response dependent: they are essentially tied to issuing the relevant experiences, so that having those experiences does give access to their, dispositional, nature. Finally, some important contrary views are critically discussed in the paper.

In recent discussions on contextualism and relativism, some have suggested that audience-sensitivity motivates a content relativist version of radical relativism, according to which a sentence as said at a context can have different contents with respect to the different perspectives from where it is assessed. The first aim of this note is to illustrate how this is not so. According to Egan himself, the phenomenon motivates at least refinement of the characteristic moderate contention that features of a single context determine the appropriate truth-value of the sentence. The second aim of this note is to explore how this may not be so.

This paper is in five sections. In the first one, I summarize some views on truthmaking I will be presupposing, emphasizing however the various controversies on which I will remain neutral. In section two and three, I present the characterization of a response-dependent property. In section four, I present two ways in which a property can be response-dependent, in the characterized sense. In final section five, I present how these correspond to different versions of moderate relativism, namely indexical and nonindexical contextualism. Thus the view presented here contrasts not only with pluralism about truth, but also with radical relativism about truth, as recently defended by John MacFarlane.

I enjoyed reading Max Kölbel's deep and interesting paper. I have learned a lot about points and arguments I am not entirely familiar with, and it has helped me to articulate better my own intuitions about the subject. In particular I share with him the intuition I would now articulate as follows: there are contents p of utterances of declarative sentences like, for instance, 'Licorice is tasty', such that it is not an objective matter whether p. This is the claim that there are non-objective truths and falsehoods, and it is a plain consequence of global truth-evaluability, i.e. the view according to which the content of utterances of all declarative sentences are truth-evaluable. For in this case one, unless radical objectivist, has to accept that for some such contents it is not an objective matter if they are true nor it is an objective matter if they are false. And Kölbel has presented some reasons for such global truth-evaluability: philosophical and linguistic semantics presupposes it, classical logical validity presupposes it, and we do in fact attribute truth to contents of utterances of declarative sentences of any sort.

According to Jackson, Pettit & Smith , “restricted particularism” is not affected by their supervenience-based consideration against particularism but, they claim, suffer from a different difficulty, roughly that it would violate the platitude about moral argument that, in debating controversial moral issues, a central role is played by various similarity claims. I present a defense of “restricted particularism” from this objection, which accommodates the platitudinous character of the claim that ordinary participants in conversations concerning the evaluative are committed to descriptive similarities and differences being relevant in the way described by Jackson, Pettit and Smith, to moral similarities and differences. My defense exploits a presuppositional component congenial to response-dependent proposals such as Lewis’s

Gonzalo Rodriguez-Pereyra (2006) argues against attempts to preserve the entailment principle (or a restriction of it) while avoiding the explosion of truthmakers for necessities and truthmaker triviality. In doing so, he both defends the disjunction thesis--if something makes true a disjunctive truth, then it makes true one of its disjuncts--, and rejects the conjunction thesis--if something makes tue a conjunctive truth, then it makes true each of its conjuncts. In my discussion, I provide plausible counterexamples to the disjunction thesis, and contend that Rodriguez-Pereyra's general defence of it fails. Then I defend the conjunction thesis from Rodriguez-Pereyra's case against it.
