 In his later works, and specifically in his works on natural philosophy, Bacon presents nature as an active agent. The form or the species is the first effect of any natural agent. The power of the species educes the emergence of the thing from the potency of matter. It does not simply produce a form/species and impose it on the matter. Matter has an active potency, and this is actualized due to the action of the natural external agent. See Michela Pereira, “Remarks on materia natualis”.
