It is important to think of what prompts the native's assent to 'Gavagai?' is stimulations and not rabbits. It is not adequate to think of the visual stimulations as momentary static irradiation patterns. To do so would obstruct examples which, unlike 'Rabbit', affirm movement. And it would make trouble even with examples like 'Rabbit', on another account: too much depends on what immediately precedes and follows a momentary irradiation. Better to take as the relevant stimulations not momentary irradiation patterns, but evolving irradiation patterns of all durations up to some convenient limit or modulus. One that shows the rabbit too peripherally simply will not be one that prompts assent to 'Gavagai' or 'Rabbit'(wo31)
