A bird’s wing shape can be pointed at by the derivation we call ‘an airfoil’. That is true. It’s a fact. It’s also a fact that a bird’s wing »is not an object. It is of an entirely different order, ontologically. In the same way that your eye is not a camera, a bird’s wing is not an airfoil. This distinction is crucial to human intelligence, because collapsing nature into the likenesses of our mechanical derivations of function is a catastrophic loss of meaning-space, identity and perspective. Useful if limited in scope. Lethal if universalized.
