Modal logic flourished throughout the twentieth century. Kripke provided a semantics in terms of possible world recognized by mathematicians to be an example of varying sets. This allows a formulation in terms of monads generated by adjunctions. Modal homotopy type theory adds the radical idea that modalities apply to all types, not just propositions, so as to make sense of possible steps and necessary ingredients. The proximity is shown between the structures discovered by modal logicians and common ideas in mathematics of stability under variation. We can then reformulate many ideas in current philosophical metaphysical uses of modal logic, such as rigid designators, counterparts, the de re/de dicto distinction, and so on. Worlds are understood as extended contexts, allowing a formulation of counterfactuals. A form of temporal logic is also easily generated in the same vein.

Quine's arguments against the attribution of essential properties de re to individuals have been the motivation for attempts at reinstating essentialism as a respectable metaphysical thesis and at defending the coherence of modal logic in general.I shall argue here along somewhat different lines, that the particular version of essentialism Quine objects to is in fact untenable but that this conclusion is far from entailing a commitment to some version of conventionalism, and in particular that it does not entail the view that the only kind of necessity that is coherent is de dicto necessity.In what follows, I shall assume, without arguing for it, that de re essentialism and subjunctive conditionals are intimately related, and in particular, that any version of de re essentialism which conflicts with our basic intuitions about subjunctive conditionals is untenable.

AbstractDe Re Significance accounts of moral appraisal consider an agent’s responsiveness to a particular kind of reason, normative moral reasons de re, to be of central significance for moral appraisal. Here, I argue that such accounts find it difficult to accommodate some neuroatypical agents. I offer an alternative account of how an agent’s responsiveness to normative moral reasons affects moral appraisal – the Reasonable Expectations Account. According to this account, what is significant for appraisal is not the content of the reasons an agent is responsive to (de re or de dicto), but rather whether she is responsive to the reasons it is reasonable to expect her to be responsive to, irrespective of their content. I argue that this account does a better job of dealing with neuroatypical agents, while agreeing with the De Re Significance accounts on more ordinary cases.

Namera mi je da dijagramski postavim jednu moguću potencijalnu teoriju De-Re medija lociranu u savremenosti globalnih ekoloških, ekonomskih, ratnih i, svakako, klasnih kriza. Razmatrana je piosebna situacija transformacije slike sveta u događaj sveta, drugim rečima, načinjen je obrt od prikazivanja sveta do izvođenja sveta ili izvođenja u svetu. Postavljena je rasprava o sredstvima medijskog rada, proizvodnje i delovanja, tj. o instrumentima i njihovim konstruktivnim funkcijama. Analiziran je kontekst medijskog rada, proizvodnje i delovanja posredstvom modela dispozitiva/aparatusa. Reinterpretirana je iz agrarne nauke i ratne terminologije teorija rojeva te primenjna na novi pojam medijuma/medija. Preuzeta je i primenjena tradicionalna i moderna rasprava razlike De Dicto i De Re sudova. Postavljena je teorija De Re medija u odnosu na koncepte medijuma i medija, postmedijuma i postmedija, digitalnih i postdigitalnih medija.

De Dicto

This chapter explores philosophical issues in metaphysics. It begins by distinguishing between de re and de dicto necessity. All necessity is uniformly de re; there is simply no such thing as de dicto necessity. Indeed, in the glory days of positivism, all necessity was understood as uniformly the same: a necessary truth was always an a priori truth, while contingent truths were always a posteriori. The chapter then assesses the concept of antirealism. Antirealism is always an error theory: there is some sort of mistake or distortion or sloppiness embedded in the usual discourse. The chapter also considers paradoxes, causation, conceptual analysis, scientific mysteries, the possible worlds theory of modality, the concept of a person, the nature of existence, and logic and propositions.

De Dicto

The problem of de re modality is how, if at all, one can make sense of it. Most who have discussed this problem have assumed that modality de dicto is relatively unproblematic. It is, rather, the interpretation of sentences involving, within the scope of modal operators, singular terms or free variables which is thought to give rise to grave—and in the view of some, insuperable—difficulties. Quine has two arguments against the intelligibility of de re modality: a “logical” and a “metaphysical” one. That the “logical” argument is central to Quine’s attack is surely indisputable. But my claim that it is his basic argument is, in effect, denied by Kit Fine. I can (and do) agree with Fine that there are some significant differences between the two arguments. The most important question, for my purposes, is whether he is right to claim that the two arguments have force independently of one another.
