Scully argues that current environmental and public-health crises are directly related to our increasing disconnection from the physical and man-made world. In art, physical mark-making, whether the drawn line or sweeping brushstroke, expresses both human frailty and passion. In this talk, Scully connects these two sentiments by contending that the 'dry, linear thinking' behind conceptual art has detached the natural world from the world of art—which is why that aesthetic has fallen out of favor. Likewise in the world of human industry and praxis: If humans forget they are physical beings who are a part of nature and cannot proceed by rationality alone, they will be cast adrift from an ecosystem of which they are an integral part.
