"This book contains original, insightful, and inspiring papers on important aspects of Peirces theory of perception, the role of icons and indices in reasoning, and diagrammatic reasoning more generally. This is most certainly a must-read book for anyone interested in the most recent work on the later Peirce, theories of perception, the connection between perception and semiotics, phenomenology, visual thinking, and the constitutive role of diagrams in logic and reasoning."
