The *Abstract *of the Talk: *Ontic structural realism (OSR) began as an interpretation of Worrall’s proposal for a structural form of scientific realism compatible with the problem of theory change. Ladyman (1998) argues that construed metaphysically structural realism is also able to take account of issues of identity and individuality in quantum physics and general relativity. Different authors have taken up the idea of OSR in different ways. For some, such as Esfeld and Lam (2008) it is a view about the ontology of physics only. For French (2014) its implications for the ontology of the special sciences are eliminativist. On the other hand, Ladyman and Ross (2007) use ontic structural realism as the basis for realism about science beyond physics. This paper sets out the core components of different forms of ontic structural realism, and the arguments for them. It is argued that the form of OSR defended by Ladyman and Ross offers a unified picture of the ontologies of the sciences.* More information available on the facebook event page: https://www.facebook.com/events/839296663581556/ This talk is part of the *Lugano Philosophy Colloquia *- a series of events organized by: - *Master in Philosophy at USI* - *Ratio* – Philosophical Association - *Istituto di Studi Filosofici*, Lugano If you want to stay updated on our incoming philosophical events, please check our page https://www.usi.ch/en/feeds/15250 and subscribe to our *mailing list* <https://lists.usi.ch/mailman3/postorius/lists/philosophy.lugano.lists.usi... *. *For any question, please write to amm.map(a)usi.ch We look forward to your presence!
