‎Scarce first edition. ""In his 1818 monograph ""Ds Kontinuum"" Hermann Weyl initiated a program for the arithmetical foundations of mathematics. In the years following, this was overshadowed by the foundational scemes of Hilbert's nitary consistency program and Brouwer's intuitionistic redevelopment of mathematics. In fact, nor long after his own venture, Weyl became a convert to Brouwerian intuitionism and critized his old teachers program. Over the years, though, he became more and more pessimistic about the practical possibilities of reworking mathematics along intuitionistic lines, and pointed to the value of his own early foundational works. Weyl's work ""Das Kontinuum"" has come to be recognized for its importence as the opening chapter in the actual development of predicative mathematics, whose extent has been plumbed both mathematically and logically since the 1960'ties.""
