Opis:: The goal of the paper is to describe the role and structure of nonfoundational reasoning, i.e. a kind of argumentation that meets the revisability, the feedback, the background stability and the disputability conditions. I begin by observing that any nonfoundational reasoning has two components: the deductive and the hermeneutic. Next, against the background of Gadamer’s insightful, although somewhat vague, observations I attempt to uncover aspects of the hermeneutic component. I then proceed to reconstruct nonfoundational argumentation with the help of formal theory of belief revision, defeasible logic, and logical conception of coherence. Finally, I argue that nonfoundational reasoning is the backbone of both scientific endeavours and philosophical inquiry.

multi-agent system
Opis:: Negotiation is an interaction that happens in multi-agent systems when agents have conflicting objectives and must look for an acceptable agreement. A typical negotiating situation involves two agents that cannot reach their goals by themselves because they do not have some resources they need or they do not know how to use them to reach their goals. Therefore, they must start a negotiation dialogue, taking also into account that they might have incomplete or wrong beliefs about the other agent’s goals and resources. This article presents a negotiating agent model based on argumentation, which is used by the agents to reason on how to exchange resources and knowledge in order to achieve their goals. Agents that negotiate have incomplete beliefs about the others, so that the exchange of arguments gives them information that makes it possible to update their beliefs. In order to formalize their proposals in a negotiation setting, the agents must be able to generate, select and evaluate arguments associated with such offers, updating their mental state accordingly. In our approach, we will focus on an argumentation-based negotiation model between two cooperative agents. The arguments generation and interpretation process is based on belief change operations (expansions, contractions and revisions), and the selection process is a based on a strategy. This approach is presented through a high-level algorithm implemented in logic programming. We show various theoretical properties associated with this approach, which have been formalized and proved using Coq, a formal proof management system. We also illustrate, through a case study, the applicability of our approach in order to solve a slightly modified version of the well-known home improvement agents problem. Moreover, we present various simulations that allow assessing the impact of belief revision on the negotiation process.

Opis:: The article presents some problems of logical representation of belief change. The problem of beliefs (approached in a synchronic way) was analyzed on the ground of epistemic or intuitionist logics. In the 1980’s works concerning logical reconstruction of belief change appeared. The basic conception here is the conception of belief change formulated by C. Alchouron, P. Gärdenfors and D. Makinson (abbreviated as AGM), based on the assumption that the belief state is represented by a non-contradictory set of propositions and that a belief change should be minimal (the postulate of economy). However, the AGM theory, characterized by a good formal shape, gives rise to several problems of the intuitive nature. Some of them are: the way the object of beliefs is understood, logical value of propositions that induce a change, the propositional way of representing beliefs, putting beliefs in an order and the way this order is formally represented.
