I recently decided that it is high time I reacquaint myself with the early moderns, and I thought there could be no better place to start with than Descartes' Mediations on First Philosophy. Reading this work, I think it is evident that Descartes is carrying out his skeptical project within the framework of Foundationalism (of course, I am always eager to have my mistakes pointed out if I have wrongly interpreted him). Indeed, he writes
I can do this without showing that all my beliefs are false, which is probably more than I could ever manage. My reason tells me that as well as withholding assent from propositions that are obviously •false, I should also withhold it from ones that are •not completely certain and indubitable. So all I need, for the purpose of rejecting all my opinions, is to find in each of them at least some reason for doubt. I can do this without going through them one by one, which would take forever: once the foundations of a building have been undermined, the rest collapses of its own accord; so I will go straight for the basic principles on which all my former beliefs rested.
Not only does this passage make it evident that Descartes is presupposing some form of Foundationalism, but this passage seems to suggest that such a skeptical project makes sense only in the context/framework of a Foundationalist epistemology. I say this because it is, from what I gather, Descartes' ultimate goal to remove himself from this doubt he has entrenched himself in, and to vindicate as many those beliefs he held before embarking on this skeptical project as possible. And it only seems possible to do this by first securing those beliefs forming the foundation which then, by extension, secure his former beliefs by being justified by those foundational beliefs.
But I am now wondering whether this is mistaken, and wondering whether such a Cartesian skeptical project can be carried out within the framework of Coherentism. Is there any attempt out carry out some form of Cartesian skepticism within Coherentism? If so, what does such a project look like?
