Gary, I admit that I saw in your post an attempt to lower the role of mathematics on the path of research in Peirce's semiotics. My apology is that this has been an issue close to my heart for almost 40 years. So it was a straw man argument as you say and I apologize for that. It was therefore only for you to take advantage of John's quotation (I also apologize to him for having involved him in this dubious fight) to remind those who might have doubted it "that mathematics is not a positive science". I clumsily hoped that you would be led, on this occasion, to say something positive about the role of mathematics - although it is not a positive science, it is important to remember this - and especially about mathematical objects that did not exist in Peirce's time and about which he had a strong intuition. But it was a waste of time; only the beginning of my posts caught your attention ... so I won't do it again and I'll stop spreading terror with a humorous signature that you took perhaps a bit too seriously. There won't be blood on the walls!
