Man is but a reed, the most feeble thing in nature, but he is a thinking reed.
I’m not sure which is getting flabbier faster–my biceps or my brain. As I advance in middle age I tend to avoid overworking both to just get by with only occasional heavy lifting: a hay bale here, a challenging abstract philosophical commentary there. Hard work, whether physical or mental, is getting harder. As a naturally lazy person, I have to be forced into manual and central nervous system labor out of necessity. Necessity happens less and less often unless I go looking for it.
Given the choice between a physical task and a thinking task, I’ll opt for thinking over lifting any day. Even so, I find my mental strengths are ebbing. My brain is less flexible, I can tend to be stiff headed when trying something new, it starts to feel strained if I push it too fast. There are times when it feels like it just goes into spasm and I need to sit down and rub it for awhile. Feeble suddenly doesn’t sound like it just belongs to the aged and infirm.
The only remedy is to use it or lose it, whether muscles or gray matter. So I dig a little deeper each day, even when it hurts to do so. I purposely stretch beyond the point of comfort, just so I know it can still be done. I lift a little higher, heft a little heavier, push a little harder. Being the most feeble thing in nature may mean being easily broken by the smallest effort, but at least I’ll have thought my reedy limitations through thoroughly, chewed on it until there was nothing left and digested what I could.
Eventually I’ll come to accept that my greatest strength is to know what I don’t know.
“I have come to think that if I had the mind, I have not the brain and nerves for a life of pure philosophy. A continued search among the abstract roots of things, a perpetual questioning of all that plain men take for granted, a chewing the cud for fifty years over inevitable ignorance and a constant frontier watch on the little tidy lighted conventional world of science and daily life–is this the best life for temperaments such as ours? Is it the way of health or even of sanity?” C. S. Lewis (in a letter to his father, Aug. 14, 1925)
