Intentionality and semiotics

"How can either philosophy or science claim to discover objective truth when what is asserted exists only subjectively in the individual minds of the investigators, and in the minds they persuade? In Intentionality and Semiotics, John Deely succinctly and vigorously summarizes his solution to this problem, formulated in response to an invitation from W. Norris Clarke, SJ (to whom this book is dedicated) to address the problem before a meeting of the International Society of Thomas Aquinas within the framework of the 2003 Annual Meeting of the American Philosophical Association."--BOOK JACKET.
