 I know that the wooden table in my office, Messy, is not broken. How do I know that? I see it. Although not broken, Messy can break. How do I know that? Because the table I had before Messy, which we may call “Twin-Messy”, was a twin-sister of Messy, and it broke; and I know that Twin-Messy broke because I saw it. (Roca-Royes 2017: 226)
