Constructivism undermines realism by arguing that experience is mediated by concepts, and that there is no direct way to examine those aspects of objects that belong to them independently of our conceptualizations; perception is theory-laden. To defend realism one has to show first that perception relates us directly with the world without any intermediary conceptual framework. The result of this direct link is the nonconceptual content of experience. Second, one has to show that part of the… 
Nonconceptual Content, Causal Theory, and Realism
In this paper the connections between the nonconceptual content of perceptual states and realism are considered. In particular, I investigate the argument for realism that uses the notion of
Problems of empirical solutions to the theory-ladenness of observation
Recent years have seen enticing empirical approaches to solving the epistemological problem of the theory-ladenness of observation. I group these approaches in two categories according to their
Cognitive Penetration and Cognitive Realism
The paper addresses the issue of theory-ladenness of observation/experimentation. Motivated by a naturalistic reading of Thomas Kuhn's insights into the same topic, I draw on cognitive neuroscience
Is action-guiding vision cognitively impenetrable?
TLDR
The aim of this paper is to argue that action-guiding vision is not cognitively impenetrable and arguments that suggest otherwise rely on an unjustified identification between action- guiding vision and dorsal vision – a functional and an anatomical way of describing the mind.
Success semantics: the sequel
The aim of this paper is to reinterpret success semantics, a theory of mental content, according to which the content of a belief is fixed by the success conditions of some actions based on this
Modularity, cognitive penetration and perceptual justification
This thesis defends the cognitive penetration of perception. Cognitive penetration can be roughly defined as those cognitive influences on perceptual systems which have consequences for the

The paper argues that the reference of perceptual demonstratives is fixed in a causal nondescriptive way through the nonconceptual content of perception. That content consists first in spatiotemporal

Abstract: Philosophers have often argued that ascriptions of content are appropriate only to the personal level states of folk psychology. Against this, this paper defends the view that the familiar

TLDR
A dual-process approach to visual perception emerges, with the ecological-dorsal process transpiring mainly without conscious awareness, while the constructivist-ventral process is normally conscious.

TLDR
This book is strongly recommended to all who take an intelligent interest in the problems of the nature of man and his relationship to the world.
