K. R. Popper distinguished between two main uses of logic, the demonstrational one, in mathematical proofs, and the derivational one, in the empirical sciences. These two uses are governed by the following methodological constraints: in mathematical proofs one ought to use minimal logical means (logical minimalism), while in the empirical sciences one ought to use the strongest available logic (logical maximalism). In this paper I discuss whether Popper’s critical rationalism is compatible with a revision of logic in the empirical sciences, (...) given the condition of logical maximalism. Apparently, if one ought to use the strongest logic in the empirical sciences, logic would remain immune to criticism and, thus, non-revisable. I will show that critical rationalism is theoretically compatible with a revision of logic in the empirical sciences. However, a question that remains to be clarified by the critical rationalists is what kind of evidence would lead them to revise the system of logic that underlies a physical theory, such as quantum mechanics? Popper’s falsificationist methodology will be compared with the recently advocated extension of the abductive methodology from the empirical sciences to logic by T. Williamson, since both of them arrive at the same conclusion concerning the status of classical logic. (shrink)

The idea that the brain is an information processing system raises some challenging questions about whether information exists independently of brains. Answering these questions is relevant for clarifying the theoretical foundations of the sciences of mind and brain, but also for appropriately interpreting and evaluating the evidence about how brains—and other biological systems—work. This article claims that (1) informational descriptions in the sciences of mind and brain can be genuinely explanatory, despite assuming a mind-dependent notion of information; and (2) that (...) either Popperian objectivity or response-dependence in normal receivers is sufficient for grounding the explanatory role that information often plays in these sciences. Hierarchical predictive processing, which has become a central theoretical framework for neurocognitive research, is used as a case study for supporting these two claims. (shrink)

: In this paper I approach the problem of the boundaries and location of consciousness in a strictly physicalist way. I start with the debate on extended cognition, pointing to two unresolved issues: the ontological status of cognition and the fallacy of the center. I then propose using identity to single out the physical basis of consciousness. As a tentative solution, I consider Mind-Object Identity and compare it with other identity theories of mind. Keywords: Extended Mind; Spread Mind; Enactivism; Cognition; (...) Consciousness; Mind-Object Identity; Identity I confini e la localizzazione della coscienza secondo le teorie dell’identità Riassunto: In questo lavoro tratterò il problema dei confini e della localizzazione della coscienza in termini strettamente fisicalisti. Prenderò le mosse dal dibattito sulla cognizione estesa, portando l’attenzione su due questioni irrisolte: lo status ontologico della cognizione e la fallacia del centro. Proporrò quindi di usare l’identità per individuare la base fisica della coscienza. Come possibile soluzione, prenderò in considerazione la Mind-Object Identity, confrontandola con oltre teorie dell’identità della mente. Parole chiave: Mente estesa; Mente diffusa; Enattivimo; Cognizione; Coscienza; Mind-Object Identity; Identità. (shrink)
