spatial turn

If they [Lawrence Krauss, Stephen Hawking and Neil deGrasse Tyson] really believe this [that philosophy is a waste of time] they should stop indulging in low-grade philosophy in their own writings. You cannot do physics or cosmology without an assumed philosophical basis. You can choose not to think about that basis: it will still be there as an unexamined foundation of what you do. The fact you are unwilling to examine the philosophical foundations of what you do does not mean those foundations are not there; it just means they are unexamined.

Actually philosophical speculations have led to a great deal of good science. Einstein’s musings on Mach’s principle played a key role in developing general relativity. Einstein’s debate with Bohr and the EPR paper have led to a great deal of good physics testing the foundations of quantum physics. My own examination of the Copernican principle in cosmology has led to exploration of some great observational tests of spatial homogeneity that have turned an untested philosophical assumption into a testable–and indeed tested–scientific hypothesis. That’s good science.

On the spatial turn - processes of circulation

“There are no doubt many reasons to believe that the spatial turn will prove to be of lasting significance. But, in the final analysis, or so I would claim, the ‘spatial turn’ has proved to be a move of extraordinary consequence because it questions categories like ‘material’, ‘life’ and ‘intelligence’ through an emphasis on the unremitting materiality of a world where there are no pre-existing objects. Rather, all kinds of hybrids are being continually recast by processes of circulation within and between particular spaces. The world is made up of all kinds of things brought in to relation with one another by this universe of spaces through a continuous and largely involuntary process of encounter and the often violent training that the encounter forces.“
