The call to remember the lifeworld is part of the ancient Greek counsel: “Know yourself.” The same scientist who claims that behavior is a function of genes can’t give a genetic explanation of why she chose to become a scientist in the first place. The same philosopher who denies freedom freely chooses to present conference papers defending this view. People forget their own lifeworld every day. It’s only human — all too human.
