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 NewletterThe 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."―Nathan HouserIn 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
