Abstract: Schaefer and Zhang have recently obtained an analogue, for sequentially order continuous functionals on $C(K)$, of a much earlier theorem of Dixmier. In this note it is shown that the Schaefer-Zhang Theorem has a natural generalisation to non-commutative $C^*$-algebras. These results are obtained as consequences of our main theorem which is concerned with affine functions on compact convex sets.
