What Can the Human Sciences Contribute to Phenomenology?

What phenomenological details can investigations by human scientists provide to classical phenomenological inquiries regarding sense-constitution, the reflexivity of mundane understanding, and the production of objective knowledge? Problems of constitutional phenomenology are summarized and specifications are provided regarding ways to study intersubjective events. After a review of some quandaries suggested by an examination of Husserl, Levinas, Merleau-Ponty, Schutz, Gurwitsch, Garfinkel, and Adorno, the author provides two demonstrations of social phenomenologically inspired human studies—the playing of games with rules and the objective determination of flavors by coffee tasters—in order to identify and describe some of the local details of sense organization that the human sciences can provide to phenomenological researchers.
