The Johns Hopkins Metaphysical Club and Its Impact on the Development of the Philosophy and Methodology of Sciences in the Late 19th-Century United States

This memorandum documents some of the most noteworthy facts concerning the Metaphysical Club meetings, which were predominantly presided over by Charles Peirce, and which took place at Johns Hopkins University from October 1879 until March 1885. The Club held the total of 43 meetings, and 110 presentations, of which 33 were principal papers. These facts, some of which are highlighted in the document that follows, testify that the club had an enormous impact on the development of American sciences and methodology.
