Everything that happens in our brains, all of our thoughts, dreams and aspirations, are driven by a body which is relentless in its demands. If you doubt me, try fasting for 24 hours like Jews on Yom Kippur, and see if at the end you have a desire to compose a sonnet or a piano concerto. No, more likely you’ll be focused on where you next meal will be coming from.
We fall in love because it is our biological imperative. We may have ancestors who lacked an interest in romantic adventure, but they failed to pass on their DNA to us. This does not imply that the love we feel is insincere, any less than our enthusiasm for good food is not authentic. It’s the adaptions, in the evolutionary sense of the word, which truly make us human. We seek to form loving relationships that nourish not only our bodies but our souls, because that’s what makes us tick.
My body has just told me to get back into the sunshine, and I intend to follow its command. Not mind over matter, but matter is the mind.
