    How is Logical Analysis Viable? by Arman Besler

    Published 2024-12-01
    “…This distincive conception has been specified under a few various rubrics, such as paraphrastic or transformative-interpretive analysis, to separate it not only from the decompositional but the regressive conception as well, the latter characterizing the analysis-synthesis method of ancient Greek geometry. The present paper first locates logical analysis (as a philosophical method) in this picture, by proposing to define it as a definite kind of paraphrastic (or transformative/interpretive) analysis, the kind where the language in the analysans position is a logical language. …”
