“Our categories arise from the fact that we are neural beings, from the nature of our bodily capacities, from our experience interacting in the world, and from our evolved capacity for basic-level categorization - a level at which we optimally interact with the world. Evolution has not required us to be as accurate above and below the basic level as at the basic level, and so we are not.”
― George Lakoff, Philosophy in the Flesh: The Embodied Mind and its Challenge to Western Thought
