 Just as we can be acquainted with a person, so too can we be acquainted with a city, a species of bird, a planet, 1960s jazz music, Watson and Crick’s research, transphobia, and so on. If it’s not clear precisely what acquaintance demands in the case of people, it’s even less clear what it demands across all of these various cases. If there is a genus of cognitive success expressed by the verb “to know” with a direct object, or by the French “connaitre”, we have not yet understood that genus.
