求廊桥遗梦原著里最后几章里那段讲到欧几里德、平行线的那段原文

Euclid was not always right. He assumed parallelness, in constancy, right to the end of things; but a non-Euclidean way of being is also possible, where the lines come together, far out there. A vanishing point. The illusion of convergence.
Yet I know it's more than illusion. Sometimes a coming together is possible, a spilling of one reality into another. A kind of soft enlacing.
