Degrees of Attention and Degrees of Consciousness

A standing question in consciousness science is whether consciousness arises gradually or in a sudden way. This empirical question is connected to a metaphysical one, concerning the kind of property that consciousness is, i.e., graded or categorical. Recently, Lee (2022) suggested that settling this question requires deciding which theory of consciousness is true. Applying an insight from Wiese (2020), this chapter pursues a way of approximating answers by examining properties that are necessary for consciousness, which consciousness must have regardless of which theory turns out true in the end. One such property is attention. This chapter suggests that attention is connected to consciousness in such a way that a graded view of the former brings support for a graded view of the latter. To this effect, evidence is discussed that degrees of attention are reflected in several acknowledged dimensions of consciousness. The upshot of this view is that the transition from unconscious information processing to conscious experience is gradual and is a function of degree of attention.
