In 1955, Levi signed a contract with Einaudi for a new edition, which was published in 1958. The initial printing of 2000 copies was followed by a second of the same size. An English translation
Whitehead's point-free geometry chpt. 2 of "Process and Reality". For an advanced and detailed discussion of systems related to C, see Roeper (1997). Biacino and Gerla (1991) showed that every model of Clarke's theory is a Boolean algebra, and models of such algebras cannot distinguish connection from overlap. It is doubtful whether either fact is faithful to Whitehead's intent. Whitehead's point-free geometry In mathematics, point-free geometry is a geometry whose primitive ontological notion is "region" rather than point. Two axiomatic systems are set out below, one grounded in mereology, the other in mereotopology and known as "connection theory". A point can mark a
