In order to tackle the question posed by the title – notoriously answered in the positive, among others, by Heisenberg, Margenau, Popper and Redhead – I first discuss some attempts at distinguishing dispositional from non-dispositional properties, and then relate the distinction to the formalism of quantum mechanics. Since any answer to the question titling the paper must be interpretation-dependent, I review some of the main interpretations of quantum mechanics in order to argue that the ontology of theories regarding “wave collapse” as a genuine physical process could be interpreted as being irreducibly dispositional. In non-collapse interpretations, on the contrary, the appeal to dispositions is simply a way to reformulate the predictive content of the algorithm of the theory in a fancier metaphysical language.

In this paper I will explore the ramification ofthe distinction between fact and values in order to show that human values enter in various ways in both science and technologies without violating Humes factlvalue distinction. Among the nanotechnologies, I will discuss the case study provided by the use of microchips implanted under our skin: though they do not obviously overcome the limits of the natura! laws, their application might in principie jeopardize our ethical principles in a way that is more powerful than previously existing 'rnacrotechnology'. This greater power depends on the fact that the properties of the macroworld depend on the 'nanoworld', but not conversely.

Sellars once wrote that “‘the problem of time’ is rivaled only by the ‘mind-body problem’ in the extent to which it inexorably brings into play all the major concerns of philosophy”. Considering that time plays a major role both in our inner life and in the description of the outer world, one could suggest that two problems are deeply related: our progress in understanding bits of the problem of time might shed light into the mind-body problem and vice versa. In this paper, I will test the plausibility of this suggestion, by focusing on a fundamental aspect of the relationship between the ‘time of physics’ and the ‘time of mind’, namely the problem of their compatibility.

The paper defends two claims; Viewed from the perspective of the substantivalism/relationism debate, structural spacetime realism is a form of relationism; However, if we managed to reinforce Rynasiewicz’s point that the general theory of relativity makes the substantivalism/relationism dispute “outdated”, the re-elaboration of Stein ’s 1967 version of structural spacetime realism to be proposed here proves to be a good, antimetaphysical solution to the problem of the ontological status of spacetime.
