    Reasons to buy: The logic of advertisements
    Argumentation 16 (2): 157-178. 2002.
    This paper argues that advertisements have been wrongly conceived as appealing to the irrational. Advertisements contain a structure of argumentation, but often far more complex than would initially appear. Advertisements give reasons for consumers to choose products, voters to elect a candidate, or citizens to alter their behavior. The way they do so is to best explained in terms of their argumentative structure

    Seeing Reasons: Visual Argumentation in Advertisements (review)
    Argumentation 17 (2): 145-160. 2003.
    It is a commonplace of discussion about the impact of visual media, whether visual images in print, televisual images or the images of the internet, to claim that it functions irrationally. This paper argues against that claim. First, the assumptions about the connection between rationality and linear, written, unemotional prose are unjustified. Secondly, using analytic techniques analogous to those used in identifying argumentation in verbal text, is possible to discern arguments in visual text…Read more

    Reflective Reasoning in Groups
    Informal Logic 17 (2). 1995.
    The conception of reflective reasoning, like that of higher order thinking, has been informed by a Cartesian view of the self. Reflection is conceived of as a solipsistic process, in which persons consider their own thoughts in isolation. Higher order thinking has equally been represented as a single thinker considering thoughts at a meta-level. This paper proposes a different conception of reflection and higher order thinking, in which reflective dialogue is seen as the fundamental context in w…Read more

    This paper deals with the new cult cartoon series, "South Park". While reviled as vulgar and likely to lead children astray, it is in fact a fertile field of ethical and logical argumentation. The paper analyses in detail the argumentation of one epi sode, entitled "An elephant makes love to a pig" and shows how it can be used to teach reasoning skills.
