The man loves coffee. For years, for his entire life, he has drunk it every morning and enjoyed it. He loves the warm sensation on his tongue, the flavor that lingers in his mouth, and the obvious mental boost he relies on to work. He considers himself a connoisseur of the drink, just as he believes in the real benefits it brings to his daily life. In short: coffee makes him happy. Then comes the day when he tastes a superior-quality coffee that leaves his palate in ecstasy. When he returns to the old coffee he used to drink, he clearly realizes it is rubbish. He investigates the matter and discovers that it is indeed rubbish, in which real coffee, though made from lower-quality beans, is mixed with a wide variety of impurities, including some too unspeakable to name, and the whole lot is over-roasted to mask its defects. From that day forward, the same coffee, the drink he once cherished so much and which had brought him pleasure his whole life, will never satisfy him again. And philosophy, as it always does, poses the question: is knowledge worth it?
