What does it mean to be alive? Where do we draw the line between the living and the non-living? Is it possible not only to change our mind about where to place the border, but to transform our minds into a living thinking beyond borders? In this essay, we strive to think about life itself as a kind of belonging, which means also coming to experience how thinking itself belongs with life. We take time to exactly imagine the way a plant is, how it lives into its environment and environment lives through it. We then precisely imagine how animals live in their world in a radically different way and yet interpenetrate with plants. Finally, we see how humans are not divorced from the world but live in it as thinking beings. As living thinking, scientific research might move beyond drawing boundaries and into participating in nature’s creative unfolding.
