““The believers believe there’s something out there—some “thing” in some sense of the word “thing”—that corresponds to the word “electron”; and that, though the best we can do is conceive of this “thing” imperfectly, even misleadingly, conceiving of it that way makes more sense than not conceiving of it at all. They believe in electrons while professing their inability to really “know” what an electron is. You might say they believe in electrons even while lacking proof that electrons per se exist.””
