I develop and defend a model of downward causation denoted as downward, structural, substance causation. This model is based on the idea that higher-level, strongly emergent substances can cause something at lower levels by imposing certain structures on lower-level goings-on. After providing a sketch of the model and of its ontological assumptions, I apply it to the analysis of how free mental causes can structure neural goings-on. I defend three theses following from such an analysis, and I test the empirical plausibility of the model. Finally, I anticipate some objections and replies.

I shall defend in this paper the thesis that, if there are irreducible powers such as the power to produce a certain object (generative powers), then there are objects that do not exist and they are part of the fundamental level of the universe. Thus, generative powers come together with Meinongianism. After having clarified my argument, I shall examine and criticize Armstrong (1997)’s attempt to reduce powers to other sorts of entities. Finally, I shall deal with five accounts of generative powers that are somehow alternative to Meinongianism and with some (more general) miscellaneous concerns about the truth of this doctrine.

In this paper I shall “draw” a sketch of a version of Meinongian Presentism. After having briefly presented some data that presentists need to explain and three problems that typically affect presentism (the triviality objection, the problem of the reference of true propositions’ constituents that seem to involve merely past and merely future objects, the truthmaking problem), I shall clarify the bases of my theory. First, I shall reject the actualist presentist assumption, according to which there are no things that do not exist now. Secondly, I shall introduce some notions (e.g., the ones of tensed properties and of temporal existence) that will be useful in order to clarify the contrast between eternalist and non-eternalist metaphysical theories of time. Thirdly, I shall define Meinongian Presentism. Finally, I shall try to demonstrate that this version can deal with the aforementioned problems and with the presentist data in a serious and perspicuous way.
