 To get a feel for the hybrid picture, consider a contrast between an expert bird-watcher and an ordinary perceiver, both observing a northern bobwhite. The hybrid theorist would say that they have the same rudimentary visual sensation in some way involving colors and shapes, with only the expert has a visual seeming specifically to the effect that a northern bobwhite is present. Here the visual sensation shared by the expert and novice is sensory in character, but the seeming had only by the expert is itself not sensory. (For further examples, see the opening of Tucker 2010).
