Constructibility and Mathematical Existence
Charles S. Chihara
Clarendon Press
Chihara here develops a mathematical system in which there are no existence assertions but only assertions of the constructibility of certain sorts of things.  He utilizes this system in the analysis of the nature of mathematics, and discusses many recent works in the philosophy of mathematics from the viewpoint of the constructibility theory developed. This innovative analysis will appeal to mathematicians and philosophers of logic, mathematics, and science.
