This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)

In the philosophical literature on the definition of lying, the analysis is generally restricted to cases of flat-out belief. This chapter considers the complex phenomenon of lies involving partial beliefs – beliefs ranging from mere uncertainty to absolute certainty. The first section analyses lies uttered while holding a graded belief in the falsity of the assertion, and presents a revised insincerity condition, requiring that the liar believes the assertion to be more likely to be false than true. The second section (...) analyses assertions that express graded beliefs, exploring how mitigation and reinforcement can alter the insincerity conditions for lying. The last section considers the case of lies that attack certainty (knowledge-lies), understood as attempt to alter the hearer's graded beliefs. (shrink)

This project was undertaken as a response to a perceived deficiency regarding the role of communication in a large block of the phenomenological discourse on lying. The arguments presented here attempt to make the communication process an explicit, rather than an implicit component of this discussion. First, a ‘lie’ is explained as a communicative act that is identified by making a simple comparison between two contradictory realities, the reality presented by the lie, and some sort of ‘true’ reality. Existing discussions (...) of lying are examined and judged to be deficient because they limit their explanations of this ‘true reality’ to subjective and objective standards of truth. Intersubjectivity is presented as an alternative truth standard, and it is argued that ‘lies’ can only be discovered and understood through a process of interpretation or negotiation (dialogue) by human interactants.

The article introduces the concept of ‘argumentational integrity’ as the basis for developing ethical criteria by which contributions to argumentative discussions can be evaluated; the focus is on the derivation, definition, and specification of the concept. The derivation of the concept starts out from a prescriptive use of ‘argumentation’, entailing in particular the goal of a rational as well as a cooperative solution. In order to make this goal attainable, contributions to argumentative discussions must meet certain conditions. It is assumed (...) that participants are not only intuitively aware of these conditions, but in fact expect of themselves and others that they will not consciously violate the conditions. This assumption leads to the most general definition of the norm of argumentational integrity: Speakers must not knowingly violate the argumentative conditions. On the basis of an empirical study drawing upon classifications of unethical strategies in popular rhetorical texts, the general norm is then specified in the form of 11 ‘standards of fair argumentation’.
