Christopher William Tindale (born 1953) is a Canadian philosopher specializing in rhetoric, argumentation theory, and ancient Greek philosophy.
[2] Tindale is an editor of the journal Informal Logic, and currently serves as the chair of the Centre for Research in Reasoning, Argumentation, and Rhetoric.
He worked as a professor at Trent University for over twenty years, and served as Chair of the department of Ancient History and Classics for part of that time.
The cognitive environment, as the space in which conviction is experienced and then personalized in persuasion, has been developed in the work since the mid-nineties, culminating in the replacement of Perelman's notorious universal audience with this idea.
This is to be seen in the Oxford textbook (co-authored with Leo Groarke) in its fifth edition, the work on fallacies (2007), and the original German text (2013) that is the first in that language to integrate logical and rhetorical features of argumentation.
