Kellert closed his speech by quoting the great environmental scientist and writer Rachel Carson, whose words perfectly encapsulated his life's work on biophilia. Carson's observation that contemplating nature's beauty creates enduring reserves of strength aligned with Kellert's research findings that human well-being is fundamentally linked to our relationship with the natural world. By ending with Carson's voice rather than his own, Kellert placed his message within a larger tradition of ecological thinking. His speech as a whole argued that even in an increasingly fabricated and artificial world, humanity must remain true to its biology rooted in nature. If we stray too far from our inherited dependence on the natural world, he warned, we do so at our peril.
