The "Ought'' Implies "Can'' Principle : A Challenge to Collective Intentionality

In my paper I investigate collective intentionality (CI ) through the “Ought” implies “Can” (OIC ) principle. My leading question is does OIC impose any further requirement on CI ? In answering the challenge inside a Searlean framework, I realize that we need to clarify what CI 's structure is and what kind of role the agents joining a CI -act have. In the last part of the paper, I put forward an (inverted) Hartian framework to allow the Searlean CI theory to be agent sensitive and cope with the problems that emerged.
