 Through much of the first two decades of this century, philosophers were largely content with this definitional approach to disability as a relationship or interaction, disagreeing primarily on the comparative contribution of the two elements and the policy relevance of their contributions. As noted in the last section, dissenters mainly focused on the characterization of one or both elements, as, e.g., on the first as social vs. biological, rather than on the “anatomy” itself. More recently, however, there has been some movement away from reliance on these two-part approaches to defining disability (e.g., Barnes 2016, and much of the literature responding). One reason may be that in most settings, we do not think of or refer to disabilities as relationships or interactions, but as individual somatic or psychic traits, states or conditions (including absences and deficiencies). These commonsense referents are hard to find in, for example, the multifactorial charts by which the ICF illustrates its definition of disability as a complex interaction of health conditions with environmental, social, and personal factors.
