I present and develop the view that omissions are de re possibilities of actual events. Omissions do not literally fail to occur; rather, they possibly occur. An omission is a tripartite metaphysical entity composed of an actual event, a possible event, and a contextually specified counterpart relation between them. This view resolves ontological, causal, and semantic puzzles about omissions, and also accounts for important data about moral responsibility for outcomes resulting from omissions.

Using a framework from recent metaphysics and philosophy of science, according to which we have two concepts of cause, producer and necessary condition, we investigate causal notions in Antiphon’s Second Tetralogy, which concerns the unintentional homicide of a boy by a javelin-throwing youth. The prosecution maintains that the youth, having produced the boy’s death, is legally responsible; the defense argues, first, that the youth is patient, not agent, of a missing-the-target, and second, that the boy’s death depends on his running (...) into the javelin’s path, so that identifying the cause requires evaluating the contrasts implicit in any causal claim.

Whether there exist causal relations between guns firing and people dying, between pedals pressed and cars accelerating, or between carbon dioxide emissions and global warming, is typically taken to be a mind-independent, objective, matter of fact. However, recent contributions to the literature on causation, in particular theories of contrastive causation and causal modelling, have undermined this central causal platitude by relativising causal facts to models or to interests. This thesis flies against the prevailing wind by arguing that we must pay (...) greater attention to which elements of our causal talk vary with context and which elements track genuine features of the world around us. I will argue that once these elements are teased apart we will be in a position to better understand some of the most persistent problems in the philosophy of causation: pre-emption cases, absence causation, failures of transitivity and overdetermination. The result is a naturalist account of causation, concordant with the contextual variability we find in our ordinary causal talk, and parsimonious with respect to the theoretical entities posited.
