 In its current state of development, informal logic’s connection to philosophy does not lie in its influence on key philosophical disciplines so much as their influence on it. In North America and elsewhere, informal logic is a field in which philosophers apply theories of argument (rationality, knowledge, etc.) to everyday argument. In keeping with this, philosophers continue to be the core contributors to informal logic; philosophy departments in colleges and universities continue to be the core departments that teach the courses that are its pedagogical focus.
