"Every thoughtful mathematician or student of the philosophy of science or mathematics will want to read this book....superbly lucid and well-presented work....highly recommended for upper division undergraduate through professional collections." Choice
"In this engaging, provocative manifesto, Professor Hintikka breaks the ground for what he hopes will be a revolution in logic, in much the same "critical and constructive" spirit as motivted Bertrand Russell...Hintikka claims that present-day logic, with its basis in a beautiful proof theory, is the result of abandoning the idea that logic can have any major role to play in mainstream mathematical...this highly readable, wide-ranging book deserves a great deal of attention and debate."

This book, written by one of philosophy's pre-eminent logicians, argues that many of the basic assumptions common to logic, philosophy of mathematics and metaphysics are in need of change. Jaakko Hintikka proposes a new basic first-order logic and uses it to explore the foundations of mathematics. This new logic enables logicians to express on the first-order level such concepts as equicardinality, infinity, and truth in the same language. Hintikka's new logic is highly original and will prove appealing to logicians, philosophers of mathematics, and mathematicians concerned with the foundations of the discipline.
