  Part 5 deals with the forerunners or anticipations of the new philosophy, and Bacon emphasizes that the ‘big machinery’ of the Instauratio Magna needs a good deal of time to be completed. Anticipations are ways to come to scientific inferences without recourse to the method presented in the Novum Organum. Meanwhile, he has worked on his speculative system, so that portions of his Second Philosophy are treated and finished: De Fluxu et Refluxu Maris and Thema Coeli. For this part of the Great Instauration, texts are planned that draw philosophical conclusions from collections of facts which are not yet sufficient for the use or application of Bacon's inductive method.
