Definition preserves_terminal_functor_to_partial_setoids (H : first_order_hyperdoctrine) : preserves_terminal (functor_to_partial_setoids H). Proof. use preserves_terminal_chosen_to_chosen_z_iso. - exact (hyperdoctrine_terminal_type H). - exact (terminal_partial_setoid H). - apply identity_z_iso. Defined.
