Constructs a lucid analysis of the structure of the Tractatus, the terminology used within it and the various interrelationships between its different statements. Stenius concludes that many adherents and critics have misunderstood the main lines of thought. In particular, its basic idea of the "picture theory" of linguistic symbolism remains insufficiently understood and little discussed. Stenius aims to untangle the misunderstandings surrounding the book, often through parallels with Kant.
No rating as I find the text engaging in reasoning stemming from a misunderstanding of the original text. It may be correct to analyse the original text in such a way, as the original author has claimed to be part of the philosophical path that is used for the analysis, but as I read the original statement being analysed it reads to me as on its face fully understandable - and the text engages in analysis that either reads the original text an a way that is contradictory to the original statements or misunderstanding it.
