The taste of a wine, like the taste of everything, is not merely the sum of that alcoholic liquid in the glass. It cannot be deduced by beginning with our sensations and extrapolating upwards. This is because what we experience is not what we sense. Rather, experience is what happens when our senses are interpreted by our subjective brain, which brings to the moment its entire library of personal memories, wine shop factoids and idiosyncratic desires. As the philosopher Wilfrid Sellars pointed out, there is no reasonable way to divide sensory experience into what is “given to the mind” and what is “added by the mind.” (Sellars referred to this as the “Myth of the Given.”) When we take a sip of wine, for instance, we don’t taste the wine first, and the cheapness second. We taste everything all at once, in a single gulp of thiswineisplonk, or thiswineisexpensive. As a result, if we think a wine is cheap, it will taste cheap. And if we think we are tasting a grand cru, then we will taste a grand cru. Our senses are vague in their instructions, and we parse their inputs based upon whatever other knowledge we can summon to the surface.
