    The Internal Aspect of Social Rules
    Oxford Journal of Legal Studies 35 (2): 283-300. 2015.
    For a rule to exist in a society, its members must hold a certain attitude. It has proven difficult to identify that attitude, however. Here, I draw on recent work in the philosophy of action to show that the attitude we are looking for is ‘acceptance’ that the rule ought to be complied with, where this acceptance is held independent of any belief about the matter. One implication of this idea is that the attitude that underlies a social rule is analogous to a ‘presumption’ or ‘fiction’ about wh…Read more

    Law's boundaries
    Legal Theory 26 (2): 103-123. 2020.
    The norms of a legal system are relevant in deciding on people's rights and duties within that system. Some norms that are not part of a legal system are also relevant within it: norms of foreign legal systems, games, clubs, contracts, grammar, and so on. What distinguishes the norms of a legal system from the norms merely relevant within it? Where, in other words, are law's boundaries? There are three existing answers in the literature, from Kramer, Shapiro, and Raz. None succeed. A better answ…Read more

    Copyright © 2015 Massachusetts Medical Society.BACKGROUND The prediction of clinical behavior, response to therapy, and outcome of infiltrative glioma is challenging. On the basis of previous studies of tumor biology, we defined five glioma molecular groups with the use of three alterations: mutations in the TERT promoter, mutations in IDH, and codeletion of chromosome arms 1p and 19q. We tested the hypothesis that within groups based on these features, tumors would have similar clinical variabl…Read more
