 Not everyone agrees that the method employed in Meditations is the method described in the Discourse and the Rules. Some scholars have very plausibly argued that the “method of doubt” in Meditations constitutes a distinct method. In Meditations, Descartes actively resolves “to doubt all previous beliefs by searching for grounds of doubt” (Curley 1978: 43–44; cf. Broughton 2002: 2–7). Descartes does not resolve to doubt all of his former opinions in the Rules. Furthermore, in the case of the anaclastic, the method of the Rules requires reducing complex problems to a series of simpler problems; solving the simplest problem by means of intuition; and solving the more complex problems by means of deduction (see  Section 3).  It is difficult to discern any such procedure in Meditations (Garber 1992: 49–50 and 2001: 44–47; Newman 2019). Other scholars have argued that Descartes’ method in the Rules does play an important role in Meditations. Descartes’ metaphysical principles are discovered by combining simple natures, such as the combination of thought and existence in the performance of the cogito in Discourse IV and Meditations II (see Marion 1992 and the examples of intuition discussed in  Section 2.2  above). A recent line of interpretation maintains more broadly that Descartes’ method can be applied in different ways. Different types of problems must be solved differently (Dika and Kambouchner forthcoming). The method of doubt is not a distinct method, but rather an application of the same method to a different problem.
