I think we’ve made the argument well enough for our present purposes. Circadian, ultradian and infradian rhythms do enter cellular processes through evolutionary selection. At least in low-level cellular and organ functions they do. To get from here to love and wisdom and the other meaning-bestowing rhythms in human life is harder. We have bigger steps to take. We have to discover how high up the same rhythms go. Do they penetrate behavior? Do we love as well as make love in rhythm? Do the fruits of wisdom deliver themselves on rhythmic trains of association? Do the oscillatory characteristics of behavior influence our values via our sense of timing? Do our attitudes, motivations, passions and possibilities congeal from rhythmic units? Do rhythms drive history?
     Our review of the rhythms of nature taken up by life,  though providing us with important information,  does not seem to help us answer the most  important questions –  how the meaning of life  could in any way depend on the interactions  of bio-oscillators. Or even that love and wisdom are oscillatory processes to which we resonate. Or how they could have become so by evolving from primitive environmental precursors. But when you look at life in the frequency domain, when you take on that perspective, when you envision the whole thing as a temporal unfolding, when you see all of “Nature naturing” (Spinoza’s phrase,) when you understand the continuity of rhythms, a pathway to love and wisdom set deep in the tissue of life opens up to you.
   I  will next show how two primordial rhythms, the very ur-rhythms of animate nature, evolve and lead the way to love and wisdom.
