There have been several different and even opposed conceptions of the problem of logical constants, i.e., of the requirements that a good theory of logical constants ought to satisfy. This paper is in the first place a survey of these conceptions and a critique of the theories they have given rise to. A second aim of the paper is to sketch some ideas about what a good theory would look like. A third aim is to draw from these ideas and from the preceding survey the conclusion that most conceptions of the problem of logical constants involve requirements of a philosophically demanding nature which are probably not satisfiable by any minimally adequate theory.

Quotation marks are ambiguous, although the conventional rules that govern their different uses are similar in that they contain quantifications over quotable expressions. Pure uses are governed by a simple rule: by enclosing any expression within quotation marks one gets a singular term, the quotation, that stands for the enclosed expression. Impure uses are far less simple. In a series of uses the quotation marks conventionally indicate that (part of) the enclosed expression is a contextually appropriate version of expressions uttered by some relevant agent. When the quotation marks have this meaning, it is tempting to think of them as contributing that indication to the truth-conditional content of the utterance. I adopt a cautious attitude towards this hypothesis, for the evidence in its favor is inconclusive. In other uses the quotation marks conventionally indicate that the enclosed expression should be used not "plainly" but in some broadly speaking "distanced" way, or that it is being so used by the utterer, and typically context makes clear the exact nature of the "distance" at stake. In these cases the quotation marks do not even appear to contribute that indication to the truth-conditional content of the utterance.

I offer a new objectivist theory of the contents of color language and color experience, intended especially as an account of what normal intersubjective variation in color perception and classification shows about those contents. First I explain an abstract account of the contents of (utterances of) color and other gradable adjectives; on the account, these contents are certain objective properties constituted in part by contextually intended standards of application, which are in turn values in the dimensions of variation associated with the adjectives. Then I propose an explanation of normal variations in linguistic color classification; these are postulated to be effects of differences in intended standards for the color adjectives appearing in the classifying predicates. Next, I consider a potential objection to this explanation, based on the suggestion that contextual content should be more accessible than the explanation predicts. In reply, I point out that contextual content is occasionally opaque to unsophisticated reflection. Finally, I present a companion account of the contents of color experiences on which these represent an object as lying on certain salient intervals in the chromatic dimensions, and I show how the account accommodates intersubjective variation in color perception.
