This volume of selected essays includes his work in the philosophy of language and philosophical logic, with particular focus on truth, judgment and the realism-anti-realism debate. Each essay is intended as a further contribution to previous topics covered and aims to bring them up-to-date. As such, this collection does not aspire to be the last word on a theory, but rather to advance a perspective and add relevant suggestions to understanding them further.
