11278 Telesio           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
Bernardino Telesio (1509-1588) was an Italian philosopher and natural scientist who severely opposed the practice of reasoning without reference to concrete data. His studies of plants and animals led him to believe that heat is the source of life. Francis Bacon called him "the first of the moderns".
