Opis

Introduces an original approach to foundations of mathematics, departing from Gödel and Tarski and spanning many different areas of logic.

Recenzje

'Kennedy creatively embeds Gödel's ideal of 'formalism freeness' into myriad results in contemporary logic and foundations of mathematics, offering novel historical reconstructions of Tarski and Turing. A cutting-edge work of philosophy that synthesizes, while going beyond, our current ideas about foundations.' Juliet Floyd, Boston University
