Ph&Rh meaning in General ?

Philosophy & Rhetoric is a quarterly peer-reviewed academic journal covering rhetorical theory, ethics, continental philosophy, informal logic, argumentation theory, critical social theory, and political theory. It is published by Penn State University Press and was established in 1968. The editor-in-chief is Erik Doxtader (University of South Carolina). The journal was established in 1968 by Henry Johnstone Jr. and Carroll Arnold, who saw a need for a journal that would, among other things, investigate "rhetoric as a philosophical concept".

Johnstone was the journal’s first editor, serving from 1967 to 1977, and then again from 1987 to 1997. Next to Johnstone, Gerard A. Hauser was the longest serving editor of the journal, filling the post from 1987 to 1993, and then from 2003 to 2017.
