In this paper, I discuss some of the recent developments in the political turn of Social Epistemology, focusing on the notions of epistemic injustice and epistemic oppression. In the first part of the work, I introduce Kristie Dotson’s characterization of the epistemic injustices presented by Miranda Fricker, through the understanding of systematic ways of violating epistemic agency in terms of oppressions. In the second part, I discuss Dotson’s critique of Fricker on the grounds that there is an important kind of (...) epistemic injustice that is not dealt with in Fricker’s proposal, and which could help us to perceive a particular, pervasive kind of violation of the epistemic agency.

In his ecological approach to perception, James Gibson introduced the concept of affordance to refer to the perceived meaning of environmental objects and events. this paper examines the relational and causal character of affordances, as well as the grounds for extending affordances beyond environmental features with transcultural meaning to include those features with culturally-specific meaning. such an extension is seen as warranted once affordances are grounded in an intentional analysis of perception. toward this end, aspects of merleau-ponty's treatment of perception (...) are explored. finally, a resolution of the apparent tension between the relational and perceiver-independent nature of affordances is presented.

Different explanations of color vision favor different philosophical positions: Computational vision is more compatible with objectivism (the color is in the object), psychophysics and neurophysiology with subjectivism (the color is in the head). Comparative research suggests that an explanation of color must be both experientialist (unlike objectivism) and ecological (unlike subjectivism). Computational vision's emphasis on optimally prespecified features of the environment (i.e., distal properties, independent of the sensory-motor capacities of the animal) is unsatisfactory. Conceiving of visual perception instead as the (...) visual guidance of activity in an environment that is determined largely by that very activity suggests new directions for research. (shrink)

The ecological realist concept of information as environmental specification is discussed. It is argued that affordances in ecological realism could, in principle, rest on a notion of partial specification of environmental circumstances. For this aim, a notion of Gestalt quality as a hierarchical structure of affordances would have to be adopted. It is claimed that such an account could provide a promising way to deal with problems of intentionality in perception and action, awareness and problem solving.

This article responds to two unresolved and crucial problems of cognitive science: (1) What is actually accomplished by functions of the nervous system that we ordinarily describe in the intentional idiom? and (2) What makes the information processing involved in these functions semantic? It is argued that, contrary to the assumptions of many cognitive theorists, the computational approach does not provide coherent answers to these problems, and that a more promising start would be to fall back on mathematical communication theory (...) and, with the help of evolutionary biology and neurophysiology, to attempt a characterization of the adaptive processes involved in visual perception. Visual representations are explained as patterns of cortical activity that are enabled to focus on objects in the changing visual environment by constantly adjusting to maintain levels of mutual information between pattern and object that are adequate for continuing perceptual control. In these terms, the answer proposed to (1) is that the intentional functions of vision are those involved in the establishment and maintenance of such representations, and to (2) that semantic features are added to the information processes of vision with the focus on objects that these representations accomplish. The article concludes with proposals for extending this account of intentionality to the higher domains of conceptualization and reason, and with speculation about how semantic information-processing might be achieved in mechanical systems.

In this article, James Gibson’s influential notion of “perceptual affordances” is applied to the romantic realm. The core idea of Gibson’s view rests on the possible, meaningful actions that the perceptual environment offers the animal. In order to sustain this idea, Gibson posits two additional major characteristics of affordances: (a) affordances are perceived in a direct cognitive manner, and (b) affordances have a unique ontological status that is neither subjective nor objective. While I accept the core idea, I have doubts (...) as to whether the two other characteristics are necessary in other types of affordances, such as social and romantic affordances. The romantic realm offers an abundance of many enticing affordances. In this regard, I discuss phenomena like the availability of a romantic alternative, romantic ambivalence, choosing a romantic partner, sexual fantasies, the road not taken, reciprocity, playing hard to get, cultivating backup mates, romantic affordances in old age and in the digital realm. In light of the abundance and complexity of romantic affordances in our current romantic environment, knowing the nature of these affordances is most useful from both pragmatic and theoretical viewpoints.

Concepts are the building blocks of higher-order cognition and consciousness. Building on Conceptual Spaces Theory (CST) and proceeding from the assumption that concepts are inherently dynamic, this paper provides historical context to and significantly elaborates the previously offered Iterative Subdivision Model (ISDM) with the goal of pushing it toward empirical testability. The paper describes how agents in continuous interaction with their environment adopt an intentional orientation, estimate the utility of the concept(s) applicable to action in the current context, engage in (...) practical action, and adopt any new concepts that emerge: a largely pre-intellectual cycle that repeats essentially without interruption over the conceptual agent’s lifetime. This paper elaborates utility optimization by establishing three constraints on concept formation/evaluation – non-redundancy, distinctiveness, and proportionality – embedding them in a quasi-mathematical model intended for development into a formal logic. The notion of a distinctor – a quality dimension of the conceptual space in focus at any given time, used for making what we call a difference distinction – is key. The primary contribution of the revised ISDM is the way it relates concepts to action via utility optimization/actualization and the way it describes the emergence of quality dimensions through trial-by-action (trial and error), something previous presentations of CST have failed to address.

This paper proposes an ecological approach to the perception and interpretation of signs. The theory draws upon the ecological approach of James Gibson . It is proposed that cultural and natural perception can both be explained in terms of the direct pick-up of structured information and the Gibsonian concept of affordances without having to invoke a sharp distinction between direct and indirect perception. The application of the theory is exemplified through attention to language and to the visual and audio arts.
