 Thus, in relation to Figure 2, \(C_1\), \(C_2\),…, \(C_r\) describe specific conditions (referred to as “initial” or “antecedent”) and \(L_1\), \(L_2\),…, \(L_k\) general laws, where “\(E\)” describes the event to be explained. The explanation takes the form of an inductive or deductive argument, where the premises are called the “explanans” and the conclusion the “explanandum”.
