"Sheriff's text moves the "guess" to a new level of understanding, while integrating much of Peirce's philosophy, and provokes many questions." -- Society for the Advancement of American Philosophy Newletter

"The purpose of Sheriff's work is to expound Peirce's unified theory of the universe -- from cosmology to semiotic -- and to discuss its ramifications for how we should live. He concludes that Peirce has given us a theory we can live with. The book makes an important contribution to philosophy of life and to the humanities in general."Â -- Nathan Houser

"In clear and concise prose, Sheriff describes Peirce's 'theory of everything,' a vision of cosmic and human meaning that offers a positive alternative to popular pessimistic and relativistic approaches to life and meaning." -- Peirce Project Newsletter
