Phyllis, List,io That sounds like an excellent application of Peirce's philosophy in education. My only comment would be that Peirce discovered his three categories long before he began to write about phenomenology or phaneroscopy. One of his inspirations was the 12 categories, which Kant organized as a table with four columns and three rows. After studying that table, Peirce reinterpreted Kant's categories in terms of relations with one, two, or three pegs. That was many years before he used the terms phenomenology or phaneroscopy. In fact, it may have been one of the inspirations for his 1877 theory of relatives, which he later developed into his algebra of logic (1880, 1885) and his graph logic (1896). He didn't begiin to apply logic (formal or mathematical version) to develop phenomenology until 1902, 1903. When he began to write his classification of the sciences, he considered phenomenology/phaneroscopy to be the branch of philosophy in which those categories woulld be derived by using mathematical logic (either his algebraic notations or his new existential graphs) as the representation for the categories. Your success in teaching adolescents how to use the categories confirms Peirce's the elements of logic to teaching students at a high-school or even junior high school level. John
---------------------------------------- From: "Phyllis Chiasson" <phyllis.marie.chias...@gmail.com> My experience with Peirce's phenomenology began with teaching adolescents how to"do" the three categories in order to improve reasoning and writing skills. I used Upton & Sampson's workbook, Creative Analysis. The system is simple, the results were phenomenal. Because of this experience over 45 years ago, I found the rest of Peirce's philosophy easy to understand as well. I think of his construct as a tool for thinking with very clear and simple applications. Even young children can learn to use the categories effectively.
