Second, problems arise from repeated applications of transmission principles.  For one thing, means to means to an end may actually undermine the end.  Suppose, to take an example of Ryan Millsap’s (2009a—see the Other Internet Resources), Kenny has reason to bake both a loaf of bread and a cake for a display on Marie Antoinette.  A (necessary) means to that end is baking a loaf of bread.  Plausibly, he has reason to bake a loaf of bread.  A (sufficient) means to that means is baking a giant loaf, which uses all of the flour.  But that would prevent him from baking a cake, and so prevent him from achieving the end.  So, presumably, he does not have reason to bake a giant loaf, even though it is a means to something that he has reason to do.  For another thing, if we accept both Weak Reasons Necessity and Weak Reasons Sufficiency, then repeated applications of these principles may imply that if there is reason for something, then there is reason for everything.  Suppose there is reason to E, and let F be anything. If E-ing or F-ing is a necessary means to E-ing, and if F-ing is a sufficient means to E-ing or F-ing, then, repeated application of those principles implies that there is reason to F (Millsap 2009b—see the Other Internet Resources). Note that similar problems arise if we accept both Ought Necessity and Ought Sufficiency.
