In his 2017 book Taste, the Italian philosopher Giorgio Agamben digs up the roots of the word. Historically, it is defined as a form of knowledge through pleasure, from perceiving the flavour of food to judging the quality of an object. Taste is an essentially human capacity, to the point that it is almost subconscious: We know whether we like something or not before we understand why. “Taste enjoys beauty, without being able to explain it,” Agamben writes. Algorithms are meant to provide surprise, showing us what we didn’t realise we’d always wanted, and yet we are never quite surprised because we know to expect it.
