The Logic Alphabet should be compared with other, historically competing "iconic" binary logical-connective notations like those of Charles S. Peirce, Jerome Frazee, G. Spencer Brown, and Glenn Clark, as well as other "operations on connectives" in work of Karl Menger, A. Stern's "Matrix Logic", and others. Also, Entitative Graphs, Existential Graphs, Conceptual Graphs, and VennLISP. Also, "logically onomatopoeic" connectives in certain constructed languages like Loglan and Lojban.

The Logic Alphabet, unlike some of its linear notation competitors, has the possible "defect" that symmetric binary connectives have logical symbols that are not left-right bilaterally symmetric.65.19.15.158 (talk) 10:05, 26 November 2007 (UTC)
