Building on our diverse research traditions in the study of reasoning, language and communication, the Polish School of Argumentation integrates various disciplines and institutions across Poland in which scholars are dedicated to understanding the phenomenon of the force of argument. Our primary goal is to craft a methodological programme and establish organisational infrastructure: this is the first key step in facilitating and fostering our research movement, which joins people with a common research focus, complementary skills and an enthusiasm to work together. This statement—the Manifesto—lays the foundations for the research programme of the Polish School of Argumentation.

The aim of the paper is to explore the interrelation between persuasion tactics and properties of speech acts. We investigate two types of arguments ad: ad hominem and ad baculum. We show that with both of these tactics, the structures that play a key role are not inferential, but rather ethotic, i.e., related to the speaker’s character and trust. We use the concepts of illocutionary force and constitutive conditions related to the character or status of the speaker in order to explain the dynamics of these two techniques. In keeping with the research focus of the Polish School of Argumentation, we examine how the pragmatic and rhetorical aspects of the force of ad hominem and ad baculum arguments exploit trust in the speaker’s status to influence the audience’s cognition.
