  Since for Bacon the formal necessity of the syllogism does not suffice to set up first principles, his method comprises two basic tasks: (1) the discovery of forms, and (2) the transformation of concrete bodies. The discovery from every case of generation and motion refers to a latent process according to which efficient and material causes lead to forms; but there is also the discovery of latent configurations of bodies at rest and not in motion (Bacon IV [1901], 119–20).
