“Hobbies provide more examples. If you are a gardener, what you see when you visit Sissinghurst Castle is different from what a non-gardener sees. Your judgment of the quality of the garden has an element of the objective that goes beyond sentiments about how pretty the flowers are. If you are a stamp collector, the reasons you value a particular stamp involve aspects of it that someone who isn’t a stamp collector overlooks. If you are an oenophile, your judgment of the quality of a wine has an element of the objective that goes beyond sentiments of how good it tastes. Expertise changes the quality of the experience, and also introduces an element of the objective.””

“YOUR OPINION OF EXPERTISE IN YOUR OWN FIELD OF EXPERTISE Experts are in bad odor these days. In courtrooms, expert witnesses flatly contradict each other. In the media, experts analyze the news in ways that reflect Hume’s concept of sentiment rather than his concept of judgment. But away from the spotlight, expertise still has a meaning that virtually all readers can understand for themselves because virtually all of you can call upon something in your life on which you are an expert. Now ask yourself whether you share this common tendency: On topics about which we know little, we are dismissive of the importance of expertise (“I don’t know much about art, but I know what I like”). On topics about which we know a great deal, we are dismissive of amateur opinions. The difference between these two reactions is that one has an empirical basis and the other doesn’t. On topics about which we know little, we by definition have no way of knowing that expertise is unimportant. On topics about which we know a lot, we have concrete reasons for concluding that amateur observations are either wrong or boringly obvious.””

“If one person is to be singled out as the one who took that step, it should be Édouard Manet (1832–1883). The painting is not a window on the world, Manet announced. It consists of patches of color on a two-dimensional surface. You don’t look through a painting but at it. Manet proclaimed further that “realism” does not consist of a Kalf-like fidelity to the way things look when they are minutely inspected. When people observe a scene in real life, they perceive it as a whole, focusing on some objects and not on others; seeing motion, with all its blurriness, rather than movement frozen in time; seeing light and shapes rather than specific clouds and shadows.””
