Based on Michel Foucault’s description of how knowledge is created and Stephen Toulmin’s philosophy of human understanding, this essay uncovers what it means for a branch of knowledge to be a discipline. This deconstruction explains certain disciplinary misconceptions existing within the IS field and addresses the field’s disciplinary status. Although the findings suggest that the IS field does not yet qualify as a discipline in its own right, they show that as soon as the members of the IS field can reconstitute the field’s meta-theoretical structure and scholarly content, it is certainly capable of reaching that status.
