MISCELLANEOUS NOTEBOOKS (MS 1584-1613)
In logic, CSP states that he has studied every important system except the second edition of Sigwart. But he is most devoted to the theory of knowledge and secondly to cosmology. Reading in esthetics, ethics, theology, and psychology. Plato read mainly in translation; Aristotle in the original. "Have read and thought more about Aristotle than about any other man." (It is difficult to tell whether this remark was meant to apply generally, since it was made in the context of his discussion of Greek philosophy.) Indeed the manuscript doesn't get beyond CSP's reading in Greek philosophy, ending with Epicureanism and atomism.
