> "Perception is more actively engaged in making sense of the world than is commonly thought. And yet it is characterized by curious passivity. Our perceptual relation to the world is robustly guided by the offerings of the sensory input. And yet the relation is indirect and marked by a somewhat disconcerting fragility. The sensory input to the brain does not shape perception directly: sensory input is better and more perplexingly characterized as feedback to the queries issued by the brain." (p. 2)
