From the reviews: "Diagrams will never be the same. A fascinating and challenging tour through phenomenology, biology, Peirce's theory of signs and Ingarden's ontology of literature, all neatly tied together through the guiding thread of the diagrammatical. A veritable tour de force." (Barry Smith, SUNY at Buffalo, U.S.A.) "The volume Diagrammatology can and should be regarded as it is intended, as a controversial, indeed iconoclastic, contribution to semiotic inquiry. This book is undoubtedly significant, erudite, meticulous and fluent in writing. Its voluminous output is fully justified in scholarly and intellectual terms: this book represents a masterful achievement in semiotic studies, one that should find its place in tertiary libraries." (Geoffrey Sykes, International Journal for the Semiotics of Law, Vol. 21, 2008) "Stjernfelt accomplishes a rarely achieved clearness in presenting key features of Peircean semiotics. In addition, this approach is rewarded by a true discovery that might prove to be of far reaching consequence." (Thomas Riese, Biosemiotics, Vol. 1, 2008) "Peirce and Husserl were mathematicians who had common interests in language, ontology, and phenomenology. Yet the terminology they coined was so different that they misunderstood one another: each accused the other of 'psychologism'. With his meticulous scholarship, Frederik Stjernfelt shows that they had a closer affinity to one another than either had to Frege or Heidegger. In fact, the writings of each frequently illuminate and extend the insights of the other. This book shows that Peirce and Husserl were cultivating a broad and fertile common ground, which was largely neglected by both the analytic and the continental philosophers during the 20th century and which promises to be an exciting area of research in the 21st." (John F. Sowa, Croton-on-Hudson, U.S.A.) "[...] Stjernfelt succeeds in at least two ways. First, he provides a key for an overall treatment of this very fascinating topic which in recent years has been investigated from the points of view of the most different and various fields of research. In doing so, he does not neglect the complexity of the topic but, on the contrary, shows all the different issues that can be connected with or elucidated by it. Secondly, he puts forward interpretations of Peircean semiotics and Husserlian phenomenology that stress similarities between the two, thereby opening up not only a series of questions about the evidence in support of his claims, but also a relatively new perspective that brings closer two traditions which until now have not been treated as deriving from similar ideas." (Valeria Giardino, Notre Dame Philosophical Reviews, July 2008) "Diagrammatology offers - finally - a systematic articulation of the Peircean work on the diagram, in all its complex interconnections with other developments of pragmati(ci)sm." (Riccardo Fusaroli, Versus 106-108, 2009)
