The most important discovery inFuture Logicisthe formalization of induction by generalization and particularization(Part VI, chapters 50-59 and the appendix).
This work is crucial because it frees formal logic, and therefore epistemology, from the oversimplification of purely deductive approaches.
But to well understand this research, one ought to get acquainted with the sections concerningcategorical modal propositions(Part II, chapters 11-17)and conditional modal propositions(Part IV, chapters 33-40).
These preliminary parts include, respectively, an inchoate formalization of thelogic of change(i.e. of the dynamic aspects of classification, seech. 17) and of certain modalities ofcausal logic(except for issues of volition).
It would be useful, to conclude this topic, to also readchapter 67.
The listed chapters would in themselves suffice, but it must be stated thatFuture Logicaddresses theepistemological context, for I understand the term “logic” in its broader sense.
In this regard, I would like to also recommend reading ofchapters 2, 4, 20, 31, 60, 61, 62, 64 and 66.
You will find asummaryof the book inchapter 68.
