Abstract

I discuss eight theses espoused or occasioned by Toulmin: (1) The validity standard is nearly always the wrong standard for real-life reasoning. (2) Little in good reasoning is topic neutral. (3) The probability calculus distorts much probabilistic reasoning. (4) Scant resources have a benign influence on human reasoning. (5) Theoretical progress and conceptual change are connected. (6) Logic should investigate the cognitive aspects of reasoning and arguing. (7) Ideal models are unsuitable for normativity. (8) The role of the Can Do Principle.

Eight Theses Reflecting on Stephen Toulmin

McMaster University

I discuss eight theses espoused or occasioned by Toulmin: (1) The validity standard is nearly always the wrong standard for real-life reasoning. (2) Little in good reasoning is topic neutral. (3) The probability calculus distorts much probabilistic reasoning. (4) Scant resources have a benign influence on human reasoning. (5) Theoretical progress and conceptual change are connected. (6) Logic should investigate the cognitive aspects of reasoning and arguing. (7) Ideal models are unsuitable for normativity. (8) The role of the Can Do Principle.
