The idea of objective value has come into disrepute in some quarters. We have an image of the natural world, well defined by physics—a world of mostly empty space filled sparsely with unimaginably tiny objects (an umbrella term for particles, fields and waves) that are governed in law-like ways. Indeed, this world, given precise definition and overwhelming empirical support, is often thought to be radically different to the world we know from experience—the world of vibrant colours and sounds, tastes and smells. The fact that our perception of the world seems to be so profoundly impoverished has led many to despair at the prospects of genuine knowledge of the world. So, this line of reasoning goes, the natural world given to us by physics has absolutely no room for objective values, as pure “atoms in the void” exhaust all of reality.
I think this line of reasoning is wrong, and shows the desperate need for philosophers to make sense of the natural world as defined by physics, with our place as human beings firmly as part of that natural world. To use a term from Wilfrid Sellars, it's the job of philosophers to navigate the way between the scientific image and the manifest image of the world. The scientific image is the “atoms in the void” picture of reality, where ordinary objects like tables and chairs are really just near-empty lattice like structures of atoms. The manifest image is what is presented to us in experience, where tables and chairs are solid objects, we have rich conscious experiences of music that touches us deeply, and, as I'll be focusing on in the remainder of this essay, objective values that bind on us whether we like it or not.
In his superb book, From Metaphysics to Ethics: A Defence of Conceptual Analysis (1998), the Australian philosopher Frank Jackson develops some tools for navigating our way between the scientific image and the manifest image.
