In George Eliot's "Middlemarch," the author reflects on the concept of consciousness and perception. The analogy of a sore palate detecting grit serves to illustrate how a troubled mind is attuned to negativity and criticism. This suggests that when someone is feeling uncomfortable or guilty, they are more likely to interpret comments or behaviors as jabs against them, even if they are not intended that way.

Eliot's insight emphasizes the influence of our internal states on how we perceive the world around us. It underscores the idea that our insecurities can distort our interpretation of others’ words and actions, leading to a heightened sensitivity to perceived slights. This commentary on human nature reveals the complexity of interpersonal interactions and the impact of our emotional struggles on our experiences.
