 Though informal logic addresses many issues relevant to core philosophical disciplines (most notably, epistemology and philosophy of mind; evident in the work of Goldman, Crosswhite, Thagard, and others), it has had limited impact on mainstream approaches to their subject matter. Woods 2000 has speculated on the reasons why. In part, informal logic’s position within philosophy reflects the broader fragmentation of philosophy within North America, Rescher 2005 (p. 4) writing that: “The most striking aspect of contemporary American philosophy is its fragmentation. The scale and complexity of the enterprise is such that if one seeks in contemporary American philosophy for a consensus on the problem agenda, let alone for agreement on the substantive issues, then one is predestined to look in vain.”
