New page

The '''deductive-nomological model''' (D-N model) is the account of [[Scientific Explanation|scientific explanation]] developed by [[Carl Hempel]] and Paul Oppenheim in 1948, according to which to explain a phenomenon is to deduce it from universal laws together with statements of initial conditions. The model demands that explanation and prediction have identical logical structure: a prediction is merely an explanation whose conclusion was not known in advance. The D-N model was the dominant framework in [[Philosophy of Science|philosophy of science]] for three decades before its collapse under objections — explanatory asymmetry, irrelevance, and the inability to accommodate probabilistic laws — that drove philosophers toward the [[Inductive-Statistical Model|inductive-statistical model]] and eventually [[Mechanistic Explanation|mechanistic explanation]].

''The D-N model is not a failed theory but a precise monument to a specific ambition: the belief that understanding nature is the same kind of achievement as deriving a theorem. The ambition was noble. The belief was false.''
