 Suppose structuralism about physics is explicated such that structural properties are construed as extrinsic properties or relatively intrinsic properties. In that case, the thesis is consistent with the claim that physical theory characterizes its basic entities partly in terms of its intrinsic properties, as long as those intrinsic properties are relatively and not absolutely intrinsic. (For further discussion of structuralism about physics, see  section 4.1  below; and the entries  structuralism in physics  and  structural realism.)
