The Society of Metaphysicians and Roofers is an organization with no discernable structure, no constitution, no officers, and no dues. Due to attrition and lack of recruitment, only a handful of members are living today.

In order to become a member, one must be a philosopher who has wondered about roofing, or a roofer who has wondered about philosophy, or an ordinary person who has wondered about roofing and philosophy.

The important thing is to live in a state of wonder. The surest indicator of membership is when one is not sure whether one is a member or not, that is, when one wonders about it.

For more perspective, see C.C. Thistlethwaites's poem, The Song of the Society of Metaphysicians and Roofers.
