In this poem, Science approaches the immaterial (the Soul) to try to explain it; but at the same time, the immaterial (Poetry) approaches Science to try to explain it, physically: so that it does not remain folded in on itself and is illuminated in every part by a light that restores subjectivity and life to its objects, and to its makers. One glimpses a Lucretian legacy in the use of metaphors that come to the rescue when reasoning cannot proceed or where one senses the need for a sudden change of plan (Carlo Cuppini)
