J. Campbell’s Attention-Empowered Relationalism
Philosopher John Campbell's relational theory of consciousness emphasizes the integral role of conscious attention in our ability to refer to and think about objects in the world. Conscious attention is the basis for reference such that our capacity to refer to objects—especially through demonstratives like “that tree” or “this cup”—depends fundamentally on conscious visual attention. He posits that to refer to an object, one must not only perceive it but also consciously attend to it, distinguishing it from its surroundings. This conscious attention enables the formation of thoughts about specific objects.

John Campbell
Professor of Philosophy
John Campbell is Willis S. and Marion Slusser Professor of Philosophy at the University of California in Berkeley, California. He works primarily in philosophy of mind, with special emphasis on questions relating to perception. His books include Past, Space, and Self and Reference and Consciousness.
Key Takeaways
Core Claim
Conscious attention is necessary to refer to and think about specific objects in the world.
How It Works
Conscious visual attention binds features into coherent objects, enabling demonstrative thought like “that tree.”
Distinguishing Idea
Reference depends on relational awareness, not internal representations or descriptive content.
Implications
Consciousness has causal power in cognition, directly shaping thought and language.
Raises the Question
Can reference or thought about objects occur without conscious attention—or at all in unconscious minds?
J. Campbell’s Attention-Empowered Relationalism
Philosopher John Campbell's relational theory of consciousness emphasizes the integral role of conscious attention in our ability to refer to and think about objects in the world. He argues that this conscious attention is the basis for reference such that our capacity to refer to objects—especially through demonstratives like “that tree” or “this cup”—depends fundamentally on conscious visual attention. He posits that to refer to an object, one must not only perceive it but also consciously attend to it, distinguishing it from its surroundings. This conscious attention enables the formation of thoughts about specific objects (Brinck, 2004; Campbell, 2002).
Attention, Reference, and Consciousness
Campbell argues that our capacity for reference is explained by our capacity to attend selectively to the objects of which we are aware; that this capacity for conscious attention to a perceived object is what provides us with our knowledge of reference. When someone makes a reference to a perceived object, one’s knowledge of which thing they are talking about is constituted by one’s consciously attending to the relevant object (Campbell, 2002).
Campbell articulates the connections between three concepts: reference, attention, and consciousness. He looks at the metaphysical conception of the environment demanded by such an account and at the demands imposed on our conception of consciousness by the point that consciousness of objects is what explains our capacity to think about them. He argues that empirical work on the binding problem can illuminate our grasp of the way in which we have knowledge of reference, supplied by conscious attention to the relevant object (Campbell, 2002).
Relational View and Cognitive Insights
Campbell builds on Bertrand Russell's notion of “acquaintance” and suggests that knowledge of the reference of a perceptual demonstrative arises from direct conscious acquaintance with the object. This means that understanding terms like “that woman” requires a conscious experience of the referent, not merely a causal or descriptive link (Brinck, 2004).
Campbell advocates a “Relational View” of perceptual experience, wherein the qualitative character of experience is constituted by the qualitative character of the perceived scene itself. According to this “naïve realism” view, experience is a direct relation between the subject and the object, rather than a representation or internal model of the object (Brinck, 2004).
To explain how conscious attention facilitates reference, Campbell incorporates insights from cognitive psychology, particularly Anne Treisman's Feature Integration Theory. He describes how spatial attention selects a location, and sensory information at that location is integrated into a coherent perceptual object. This process underlies our ability to refer to objects in thought and language.
Campbell's theory challenges views that minimize the role of consciousness in cognition. By emphasizing the necessity of conscious attention for reference and thought, he opposes epiphenomenalism—the idea that consciousness has feelings but no causal power or role. His work suggests that conscious experience is not just a byproduct of neural processes but is essential for our interaction with and understanding of the world (Campbell, 2002; Siegel, 2004).
