 The cause-law principle is aimed, in the first instance, at laws of succession, which cover singular causal relationships between events at distinct times. However, as will become clearer below, mental anomalism also takes in bridge laws that would correlate simultaneous instantiations of mental and physical predicates as well—such as ‘P1 → M1’, ‘M1 → P1’, or ‘P1 ↔ M1’. Indeed, mental anomalism rejects the possibility of any strict law in which mental predicates figure (where those predicates figure essentially, and are not redundant)—including (as we have seen  (2.3))  laws formulated with purely mental predicates (‘(M1 &amp; M2) → M3’), as well as laws with mental predicates in either the antecedent or consequent, such as ‘(M1 &amp; M2) → P1’ and ‘(P1 &amp; P2) → M1’ and mixed variants of these (see  4).
