Peirce also, along with Frege, independently discovered the existential and universal quantifiers, to name just one major contribution. His existential graphs[1] are extremely cool too. Peirce is grossly underappreciated largely due to the efforts of his less gifted but more politically astute childhood "friend" Simon Newcomb to obliterate his career and legacy. The Peirce gateway is full of great stuff[2][3]. This[4] is the companion paper to How To Make Our Ideas Clear.
