Mackie e la Teoria dell'Errore
Abstract: In a (for the most part) neglected article, and a much discussed book, J L Mackie has defended the so-called “error theory” of morality. According to the error theory (as Mackie understands it), there are no objective values, even though “folk morality” says that there are. I discuss what Mackie means when he says that there are no objective values, and expound and evaluate his arguments for the non-existence of objective values, and his defense of the claim that the “error theory” does not subvert ordinary moral views. I shall end up saying that Mackie has not made a good case for either the truth or the non-subversiveness of the thesis that there are no objective values.

The Connective View of Temporal Existence
Abstract: Things persist iff they exist at various times and are concrete iff they exist at some place or time. Both notions make use of the notion of existing at a time, or temporal existence. But what is for something to exist at a time? The aim of this paper is to put forward and explore the connective view of temporal existence, according to which
(CV) x exists at t := at t, x exists
In which a relational predicate, “exists at” is defined by means of the connective/operator “at t” and existence simpliciter (which according to standard lore is fully captured by the unrestricted quantifier). The connective view contrasts with the currently prevailing doctrine according to which temporal existence is a binary relation, whether this is identified with the relation of location (Gilmore 2006, Parsons 2007, Sattig 2006) or not (van Fraassen 1970, Simons 2001, Fine 2006, Costa 2017).
