Refs tag removed I ve removed the references needed tag because I think there are sufficient references here now for a short article and to recognise good work in improving this article I ve put in citation needed tags at points in the article itself which will need an in line citation adding The references section at the end needs to be Harvard style Author title date city publisher rather than a list of URLs The way to do this is like in the article on Jerry Fodor which has in line citations in the text linked to the full references at the end If you go to the Fodor article and try to edit it you will see what the syntax looks like I ve also added the Philosopher box from the Fodor page but don t know what to put in it I m sure Aedan can fill it out authoritatively I ll also find some categories to add this article to Talk to me
