Cristian Mariani (Milano): The indeterminate present and the open future
Abstract: Metaphysical explanations of the genuine openness of the future often appeal to objective indeterminacy. According to the received view, such indeterminacy is indeterminacy of certain future-tensed facts that obtain at the present. I shall call this view the weak indeterminate present, to distinguish it from the view I will develop in this paper, which I dub the strong indeterminate present. According to this latter view, unsettledness of future contingents has to be grounded on the indeterminacy of some present-tensed facts. In order for an indeterminate present-tensed fact to explain the unsettledness of a future-tensed fact, there has to be a connection between the two. I will argue that this connection can be provided if we look at the internal structure of the facts, namely if we provide a background theory that describes them. I shall suggest that the best way to do so is by looking at physics. In particular, in this paper I will be focusing on a family of interpretation of quantum mechanics, the so-called spontaneous collapse models, to provide an example of how to apply the model.
