 Upon her release, Mary has done two things: She has at last hosted a red sensory quality, and she has learned what it is like to experience a red quality. In experiencing it she has experienced a “what it’s like” in the first of our two senses. But the fact she has learned has the ineffability characteristic of our second sense of “what it’s like”; were Mary to try to pass on her new knowledge of a WIL property to a still color-deprived colleague, she would not be able to express it in English.
