 In view of the difficulties posed by Hempel’s dilemma and related problems, some philosophers have explored the interesting idea that to be a physicalist is not to hold some thesis or belief – that is, to hold something that may be true or false – but is rather to adopt a kind of attitude or stance. As Alyssa Ney (2008, p. 9, see also Van Fraassen 2002) develops this “attitudinal” view, for example, “physicalism is an attitude one takes to form one’s ontology completely and solely according to what physics says exists”.
