This book explores the philosophical foundations of communication studies, suggesting that communication phenomena extend beyond the scope of traditional scientific methods. It argues that communication, deeply intertwined with human behavior, cannot be fully comprehended through empirical methods alone. The book presents an epistemological alternative to empiricism in communication studies—an alternative rooted in the praxeological perspective. Drawing from the principles of rationalism, it proposes that conclusions about communication can be deduced from a priori theoretical truths, rather than empirical evidence. This book is a crucial resource for scholars in both philosophy and communication studies.
