Boole's earlier work, The Mathematical Analysis of Logic, appears here, together with an account of the notes Boole made on his own interleaved copy. Appendices contain relevant papers by contemporaries with whom the author engaged in discussion, making it possible to trace interesting developments in Boolean reasoning. 1952 edition.
It took me probably two-years to get through the whole book; as it is enriched with complex mathematical equations (some take more than two pages) to engender adequate understandings of “Probability” then follows “Logic”—It is cardinal (to which) to recognise the directional process, in order to fathom his portrayal of “Thoughts” as omnipotent, and dismembering what cannot be minified into an equation (=derogation). Also, he is a not-so-captivating writer.
