Rational manipulation is constituted by the following conditions: (i) A aims to persuade B of thesis X; (ii) A holds X to be true and rationally justifiable; (iii) A knows of the existence of evidence, argument or information Y. While Y is not itself misinformation (Y is factually correct), A suspects B might take Y as important evidence for not-X; (iv) A deliberately chooses not to mention Y to B, out of a concern that it could mislead B into believing (...) not-X; and, (v) B has no compelling reason to expect A will avoid mentioning Y in this way. A’s behavior is rational insofar as A aims to use reasons to persuade B to believe a thesis that A holds as true and justified. Yet it is manipulation because A deliberately avoids furnishing B with information that B might regard as relevant, to ensure B arrives at the correct belief. I argue that we have good reason to think that A’s action will be wrongly manipulative because it disrespects B’s consent, epistemic autonomy, and personal autonomy. That said, context is critical, and there are many times evidence is intentionally occluded that are not rational manipulation. Even so, ethical arguers should beware of ambiguous contexts, such as when there are conflicting expectations about argumentation roles and goals. (shrink)

Free speech fallacies are errors of meta-argument. One commits a free speech fallacy when one argues that since there are apparent restrictions on one’s rights of free expression, procedural rules of critical exchange have been broken, and consequently, one’s preferred view is dialectically better off than it may otherwise seem. Free speech fallacies are meta-argumentative, since they occur at the level of assessing the dialectical situation in terms of norms of argument and in terms of meta-evidential principles of interpreting how (...) and why people follow (or fail to follow) argumentative rules. Our plan here is to begin with a brief explanation of meta-argument and meta-argumentative fallacy. We will then turn to the variety of forms of the free speech fallacy, which we will explain as meta-argumentatively erroneous. (shrink)
