Dating back to antiquity, semiotics is both a "technique" and a "science" that aims to understand the nature of meaning. An academic discipline in its own right, semiotics uses signs, such as words and symbols, to think, communicate, reflect, transmit, and preserve knowledge. Since the initial publication of The Quest for Meaning in 2007, the world has changed dramatically with the advent of online culture, new technologies, and new ways of making signs and symbols. Updated to reflect these many changes, the second edition includes a comprehensive chapter on the use of semiotics in the Internet age. Written in a student-friendly style, featuring examples from everyday life, the book explains what semiotics is all about and why it is so important for gaining insights into our elusive and mysterious human nature.
