In Ten Lectures on Cognitive Linguistics and the Unification of Spoken and Signed Languages Sherman Wilcox suggests that rather than abstracting away from the material substance of language, linguists can discover the deep connections between signed and spoken languages by taking an embodied view.

Winterson, Jeanette - Gut Symmetries

Gut Symmetries is a collage of memories, snippets of scientific theory, meditations on abstract concepts like truth, and the events surrounding Jove, Alice, and Stella's affair. This is a book that demands your attention, jumping as it does from one seemingly tangential topic to another; but whereas physics still seeks a grand unification theory (GUT) to explain how everything in the universe fits together, Winterson actually finds one of her own in this satisfyingly complete fictional world.
