As long as science fails to discover the sources of life, as long as, on sea or in the sky, there is an abyss that is resistant to mathematical reckoning, as long as mankind in its steady progress is ignorant of where it's heading, as long as a mystery exists for man, there will be poetry!
Gustavo Adolfo Bécquer, Stanley Appelbaum (2006). “Rhymes and Legends (Selection)/Rimas Y Leyendas (selección): A Dual-Language Book”, p.9, Courier Corporation
