 Below we introduce Alpha Graphs as a formal system equipped with its syntax and semantics. These tools not being available to Peirce, the presentation aims to show Peirce’s EG is not intrinsically different from other formal systems. At the same time, in order to place Peirce’s graphical systems in the traditional well-developed discourse of logic, there will be an intermediate stage, that is, to read off Peirce’s graphs into symbolic language. This will make Peirce’s graphs more accessible, and at the same time support our claim that Peirce extended forms of representations with the same scope of logic as symbolic representation.
