I think it's helpful to take the specific quote that describes his apparent view:
> An elaborate study of five different methods by C. Floyd and several coworkers [Floyd, 1984] concludes that the notion of methods as systems of rules that in an arbitrary context and mechanically will lead to good solutions is an illusion.
> ...
> Where the Theory Building View departs from the methodologists is on the question of which techniques to use and in what order. On the Theory Building View this must remain entirely a matter for the programmer to decide, taking into account the actual problem to be solved.
This is not an outright rejection of methods or methodologies, only the method-centric view: The belief that there is some universally (or near universally) applicable method which can mechanically be applied to solve arbitrary problems in programming.
