The production of design-oriented knowledge cannot be dealt with fruitfully based on traditional epistemology. In this paper the concept of design artefacts is suggested as a possible backbone in a future design-oriented pragmatic epistemology. It is claimed that a general understanding of how design is mediated is a necessary first step in understanding the use and production of designoriented...

Epistemology tout court is a philosophical inquiry into the nature of knowledge (as a product) and knowing (as a process that produces knowledge). One of the epistemologist’s goals is to separate the epistemic wheat from the doxastic chaff, the knowledge from the mere belief; another one is to describe the very nature of knowledge: its features, conditions, sources, justification and limits. Fo...

This paper proposes new semantics for nondeterministic program execution, replacing the standard relational semantics for propositional dynamic logic (PDL). Under these new semantics, program execution is represented as fundamentally deterministic (i.e., functional), while nondeterminism emerges as an epistemic relationship between the agent and the system: intuitively, the nondeterministic out...

This paper presents an epistemological approach to the investigation of material properties that is opposed both to phenomenalistic epistemology and recent linguistical and ontological accounts of matter/mass terms. Emphasis is laid on the inherent context dependence of material properties. It is shown that, if this is taken seriously, some deep epistemological problems arise, like unavoidable ...

In the late 1960s, Georges Canguilhem introduced the concept of 'scientific ideology'. This concept had not played any role in his previous work, so why introduce it at all? This is the central question of my paper. Although it may seem a rather modest question, its answer in fact uncovers hidden tensions in the tradition of historical epistemology, in particular between its normative and descr...

Folk epistemology refers to a range of cognitive skills that involve epistemic concepts such as knowledge and truth. As human beings we are able to assess the truth of an utterance by another agent or whether an inference someone makes is valid. We can evaluate to what extent sources we acquire information from are reliable and whether new information we acquire should lead to belief revision. ...

Formal treatments of epistemology and epistemological issues have come a great way in recent years. Valuable results have been produced by Bayesians, in formal learning theory (also known as computational epistemology in [Kelly 96] and epistemic logic. While the first to formal approaches concentrate on learning and knowledge acquisition issues, the latter concentrate on axiomatics and validity...
