Consider the following premises. forall x_7: R(x_7) <-> S_7(x_7). ~S_7(j). R(j) or p. Can we infer ~p from them?
 From forall x_7: R(x_7) <-> S_7(x_7) we can infer R(j) <-> S_7(j). From R(j) <-> S_7(j), ~S_7(j) we can infer ~R(j). Finally, from R(j) or p, ~R(j) we can infer p, which contradicts ~p. Therefore, the answer is no.
