Esa Saarinen's deeply human and memorable lectures have spoken powerfully to Aalto University students and to the whole nation for over twenty years. At the heart of his personal approach is ‘thinking about thinking’, presented with his own distinctive lecturing style. At Otaniemi in Espoo, his philosophy and system thinking lecture series grew into a community phenomenon. The lecture recordings have had more than one million viewers, and the total time spent on viewing them totals a whopping 50 years. His farewell lecture last spring was hugely popular, and it received the media's attention as well.
