The scientist sees love and spouts some nonsense about increased oxytocin levels and pheromones, recognizing the chemical phenomena that corresponds to the emotional phenomena.
The madman sees love and spouts some nonsense about the merging of souls under the sacred matrix of ‘THE ALL’, sees it as proof of our interconnected oneness in the universe.
Both of these pictures, while perhaps reductive (or inaccurate) and incomplete, recognize valuable things and are valuable perspectives about and on the phenomena of love — one is emphasizing the biology necessary to the experience while the other recognizes the poetry, the true untruth, that is necessary to it.
Madmen (poets) and Scientists are both specialists in a field of knowledge and both bring valuable insights to the common human experience. Revoking either the poetic construct or the scientific construct is a sad decimation of dimension within experience.
