 As noted earlier, introspection is the first source of evidence about consciousness. Introspective reports bridge the subjective and objective. They serve as a behavioral measure that expresses the subject’s own take on what it is like for her in having an experience. While there have been recent concerns about the reliability or empirical usefulness of introspection (Schwitzgebel 2011; Irvine 2012a), there are plausibly many contexts where introspection is reliable (Spener 2015; see Irvine 2012b for an extended discussion of introspection in consciousness science; for philosophical theories, see Smithies &amp; Stoljar 2012).
