Cool quotation about embodied cognition

From Michael Spivey's 2004 book, The Continuity of Mind:


"Indulge me while I recount a little anecdote that epitomizes, for me, the intimate role that the body plays in cognition. One day, I spent much of the morning and afternoon mulling over in my head different versions of a few sentences for a manuscript I was working on. I was somewhat frustrated with trying to find the right wording. Later, while sitting in the audience for a visiting speaker's lecture, the phrasing for those sentences suddenly fell into place. I quickly grabbed a pen and the back of an envelope, and scribbled them down just legibly enough that as long as I transcribed them onto my computer within 24 hours, I could probably decipher the chicken scratchings. Then, a brief, inexplicable, unidentifiable motoric urge came over me. For about half a second, I felt a dire need to carry out some unspecified motor movement that would safely preserve these precious sentences that I had finally, after several hours, found a way to arrange that was likable. Then the feeling was gone. I folded the envelope, tucked it in my pocket, and then continued to ignore the visiting speaker's words while my mind uncontrollably wandered to try to explore what that weird urge had been. By running some kind of mental inventory of my body, asking what limbs had wanted to move, I gradually localized it to my left arm. i am right-handed, so this seemed slightly odd. Then I felt the remnants of the motoric urge continue to localize themselves further, down my arm to my left hand. I wiggled those fingers, and two of them seemed to want to wiggle more than the others. My thumb and middle finger seemed somehow potentiated for action. But why? Then it hit me: My thumb and middle finger had wanted to press the Command and S keys on my keyboard to save those prized sentences! My left thumb and middle finger had participated in my powerful desire to preserve those much-pondered phrasings. That, for me, is the embodiment of cognition."
