  Part 4, which Bacon called The Ladder of Intellect or Scala Intellectus, was intended to function as a link between the method of natural history and that of Second Philosophy/Active Science. It consists not only of the fragment Filum labyrinthi (Bacon III [1887], 493–504), but also includes the Abecedarium nouum naturae (OFB XIII, xxi), which was planned as a preface to all of section 4 “[to] demonstrate the whole process of the mind” (OFB XIII, xxii). Filum labyrinthi is similar to, but not identical with, Cogitata et Visa. Speaking of himself in an authorial voice, Bacon reflects on the state of science and derives his construction of a research program from the gaps and deficiencies within the system of disciplines: sciences of the future should be examined and further ones should be discovered. Emphasis must be laid on new matter (not on controversies). It is necessary to repudiate superstition, zealous religion, and false authorities. Just as the Fall was not caused by knowledge of nature, but rather by moral knowledge of good and evil, so knowledge of natural philosophy is for Bacon a contribution to the magnifying of God's glory, and, in this way, his plea for the growth of scientific knowledge becomes evident.
