Interesting comment on Sean Carroll's last AMA: he says that Steven Weinberg's book "Gravitation and Cosmology" was a way to teach General Relativity in a very anti-geometric way.

Carroll says that Weinberg wasn't interested in curvature or the geometry of spacetime. Weinberg saw things like, we have a field (the metric), and it has this dynamic, it obeys these differential equations and we solve them. That how we think about the spacetime, the curvature or the geometry wasn't relevant at all. That the only relevant stuff were dots in photographic plates. A very particle physicist point of view, Carroll says.

Carroll says that, while being humble and acknowledging that Weinberg was a much more important physicist than him, he thinks Weinberg was wrong. Carroll thinks that the metaphors and terms we use to understand science are essential to improve and go beyond of our present knowledge, and that they offer understanding.
