Spektrum-Essay Evolution
Abstract
Wir sehen Fortschritt, weil unser Gehirn dafür konstruiert ist, stets zu vergleichen und zu bewerten. Wahrscheinlich aber existiert er nur in unserer naiven Vorstellung.
Content
"Wissenschaft entlarvt Illusionen. Vor der zersetzenden Kraft ihrer schonungslosen Analyse scheint nichts sicher. Ob die Illusion von Erdscheibe und Himmelsgewölbe, das »Ich« und der »freie Wille«, ob die Linearität eines Zeitstroms oder auch nur die bunte Farbenpracht in der Welt »da draußen«. All dies gibt es nicht in einem objektiven Sinn, wie man naiv meinen könnte, sondern diese Ideen sind Konstrukte des Gehirns, die sich evolutionär bei der Meisterung des Lebens bewährt haben. Die Evolution setzt bekanntlich auf Nützlichkeit und nicht auf das bestmögliche Erkennen irgendeiner vorfindlichen Objektivität. Das »Ich« ist ein Selbstmodell des Gehirns, der »freie Wille« eine soziale Attribution, und die Farben sind vom Gehirn generierte Erlebnisqualitäten bloßer elektromagnetischer Strahlung in einer absolut farblosen Welt. Ob Fortschritte in der Kosmologie, Neurobiologie oder in den anderen naturwissenschaftlichen Unternehmungen: Paradoxerweise scheint mehr denn je Skepsis bei der erkenntnistheoretisch so bedeutsamen Frage angebracht, ob und in welcher Weise wir die Welt »da draußen« außerhalb unseres Bewusstseins überhaupt erkennen können."
