How can philosophy or science claim to discover objective truth when their arguments originate from subjective beings? In Intentionality and Semiotics, John Deely offers a controversial solution to the problem of subjectivity in inquiry. He creates an interface between semiotics and the concept of intentionality, as it appears in Aquinas’s work, to demonstrate that every sign is irrevocably linked to the reality of relations. In the process, Deely builds a bridge between classical thinkers such as Aristotle and modernists such as Heidegger and Peirce in this innovative volume.
