APPENDIX 1:OnFactorialAnalysis(Open Systems Analysis).The table below is an appendix toChapter 53(in particular,Section 5).It shows the factorial analysis of all195 gross formulas(listed in the column labeledFORMULAS), in terms of the63 factors(columnsF1-F63) in the 'open system' of mixed (natural and temporal) modality.Due to the size of the table, it is here split into three segments.The first segment [...]

FL Description

FUTURE LOGIC:Categorical and ConditionalDeduction and Inductionofthe Natural, Temporal, Extensional and Logical Modalities.The science of Logic stands at the interface between the two main branches of Philosophy, namely Epistemology (the study of knowing) and Ontology (the study of being). Its task is to determine precisely the way people can and do get to know the world [...]

APPENDIX2:Redefining Majority and Minority inFuture Logic This essay was written end March 2011 to correct certain errors spotted inFuture Logic. IntroductionIn chapter 5.2, about Propositions, I introduce the quantities ‘most’ and ‘few’ as follows:Other quantifiers define ‘some’ more precisely. Thus, ‘a few’ or ‘many’ mean, a small or large number; ‘few’ or ‘most’ mean, a minority or [...]

FL Reading Suggestions

Reading SuggestionsThe 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, [...]

CHAPTER 68.FUTURE LOGIC.1.Summary of Findings.2.Gaps to Fill.3.Concluding Words.1.Summary of Findings.Let us now, finally, try and summarize the information presented in this book on logic, part by part and chapter by chapter.I.Actual Categorical Logic.This is classical, Aristotelean logic, embellished somewhat over the centuries.1.We distinguished between the art of logic, and the science of it. The former [...]

Always keep this in mind when evaluating theories. No idea would 'make it' in the world, if it did not have some appearance of plausibility. The trick is to remove the [...]
