“What are these lines for?”—the fussy reader will ask. Narrative ones? Lines of behavior? Lines of protection? Life lines on the two authorial hands—the left and the right? Or maybe the name comes from the St. Petersburg streets on Vasilievsky Island? No, no. It’s just lines. Probably straight ones. At least that is what the author’s inner vision suggests—something that is always right. And you are holding now one of these two lines, undoubtedly parallel. In some places, though, they intersect. And in other places—they don’t, just like at school.
The point is that both school Euclidean geometry and the paradoxical geometry of Lobachevsky are correct. Because a universe in which there is only one kind of truth is impossible. For technical, as people say, reasons.
