Controversially, on this account, the process of remembering is constituted by the integration of internal and external vehicles and processes which complement one another in the completion of a cognitive task (Menary, 2006, p. 330).So, here Menary is invoking a notion of constitution (that he thinks A&A need to explicate for him) and "integration" seems to be another causal coupling kind of notion (only under a new term). So, as I read things, there are causal and constitutive notions in play here, ripe for the C-C fallacy.
The picture looks to be like this. There is a task, say, getting to the MoMA. Then there are these things brainy representations in Otto's brain and these inscriptions in this book, among other things. It is the integration--the causal coupling--between all these things that enable Otto to get to the MoMA. So, all those integrated things--all those causally coupled things--constitute the process of remembering. The fallacy looks to be that simple.
