An '''entitative [[graph (mathematics)|graph]]''' is an element of the [[graph theory|graphical]] [[syntax]] for [[logic]] that [[Charles Sanders Peirce]] developed under the name of '''qualitative logic''' in the 1880's, taking the coverage of the [[formal system|formalism]] only as far as the [[propositional calculus|propositional or sentential]] aspects of logic are concerned.
