Peirce • “A Theory of Probable Inference” (1883) The formula of the analogical inference presents, therefore, three premisses, thus: S′, S″, S‴, are a random sample of some undefined class X, of whose characters P′, P″, P‴, are samples, T is P′, P″, P‴; S′, S″, S‴, are Q's; Hence, T is a Q. We have evidently here an induction and an hypothesis followed by a deduction; thus: [Parallel Column Display] https://inquiryintoinquiry.files.wordpress.com/2022/04/peirce-on-analogy-e2… Hence, deductively, T is a Q. (Peirce, CP 2.733, with a few changes in Peirce’s notation to facilitate comparison between the two versions) </QUOTE> Figure 8 shows the logical relationships involved in the above analysis.
