The Metaphysical Society of America
Founded in 1950
Constituent of the American Council of Learned Societies

The Metaphysical Society of America is an organization of professional philosophers that meets annually to discuss issues of fundamental concern in all of the major areas of philosophical reflection. It is a society committed to the principle that philosophical thought is open to a variety of different traditions and methodologies, and at its annual meeting, it provides a forum for the discussion of the questions that have animated philosophical debate from the start. As the opening declaration of its constitution states, “The purpose of the Metaphysical Society of America is the study of reality.” The Society has no publication of its own, but has from its inception maintained a close informal relation with the Review of Metaphysics. Since 1958 it has been a constituent of the American Council of Learned Societies.

Past Presidents include Paul Weiss, Charles Hartshorne, W. E. Hocking, John Herman Randall, Errol Harris, John E. Smith, J. N. Findlay, Wilfrid Sellars, Joseph Owens, Stanley Rosen, Robert Cummings Neville, and Nicholas Rescher. More...

The MSA would like to publicly acknowledge generous donations from the following organizations:

The Paul K. Jaudes and Nancy K. Frankenberry Fund at The Chicago Community Foundation

2020 Conference Registration

Nature and its Meanings

Lawrence Cahoone, College of the Holy Cross (President)
Keynote Speaker: Mario De Caro, Università Roma Tre/Tufts University
Dates: March 19 - 22 2020

SARS-CoV-2 (coronavirus) Update: It saddens us to announce that the MSA 2020 confrence has been CANCELLED. Please see a full statement HERE.

Due to the postponement of next week’s MSA conference, we will be refunding registration fees to all interested parties. Given that we are hoping to reschedule this conference for a later date (perhaps within the next twelve months, but perhaps not until next March), those of you who have already registered have, at this time, two options:

1) You can request a refund, and we will issue it. This means you will need to re-register for the “Nature and Its Meanings” conference if/when you attend it. Of course, you may choose not to participate in or attend that meeting, so this will not be an issue.
2) You can do nothing, and we will keep you on record as having registered for this particular conference. If, at any time, you decide you want a refund, just ask, and we will refund your registration fee!

If you have any questions about this matter, or you just want to request a refund, please contact Tyler Tritten at
