This review article of Frederik Stjernfelt’s Sheets, Diagrams, and Realism (2022) argues that Peirce’s theory of iconicity with its subdivision into the image-diagram-metaphor triad must not be reduced to diagrammatic iconicity. The foundation of the triadic subdivision of the icon is not in Peirce’s diagrammatic logic but in Peirce’s cenopythagorean categories. A focus is on misinterpretations of Peirce’s concept of thirdness in the firstness of the icon. The paper argues that not only metaphors, but also comparisons, analogies, analogic arguments, and examples belong to the third class of icons.

皮尔士的标志性和他的图像-图表-隐喻三元组的重新审视：对斯特恩费尔特的表格、图表和现实主义的补充

Frederik Stjernfelt 的这篇评论文章表格、图表和现实主义（2022）认为，皮尔士的象似性理论及其细分为图像-图解-隐喻三元组不能被简化为图解象似性。图标的三元细分的基础不是皮尔士的图解逻辑，而是皮尔士的新毕达哥拉斯范畴。重点是对皮尔士的图像第一性中的第三性概念的误解。论文认为，不仅隐喻，还包括比较、类比、类比论证和例子都属于第三类图标。
