For his "An Inquiry Into Modes of Existence" project:

For a philosophy that is empirical and not simply empiricist, investigation offers the only way to ferret out its concepts and then put them to the test before proposing a version that can be submitted to critique by its peers. And yet, even though investigation as a genre benefits from a distinguished and intimidating prestige in philosophy, it is fairly unusual for an author to propose to carry out an investigation with the participation of his readers.
