Anchors in the Heavens – The Metaphysical Infrastructure of Human Life

Imagine you suddenly find yourself in the control room of a vast technological apparatus, sometime in the future, where you are told that science has satisfied all the needs of all living humans. Furthermore, you learn, the next generation of the species will not be produced in the usual way, but instead by this machine, provided only that somebody push a little red button. The catch: you have to give a reason for pushing it. You hesitate: what do you say?
     Our own world is more like this scenario than we at first may be inclined to admit, not least in the fact that, mutatis mutandis, we seem to be struggling to come up with a good answer. The problem, says Rémi Brague, is fundamentally a metaphysical one. Now, mention of ‘metaphysics’ in decent society these days is likely to elicit a smile or an unimpressed shrug. If there is a shelf with that label on it in your typical bookstore you are as likely to find guides to crystals, chakras, or hemp care there as you are treatises by Aristotle, Aquinas, or Kant. And, in spite of the ongoing revival of academic interest in metaphysics, it remains a rather specialist domain, a marginal sub-discipline in departments of philosophy, be they analytical or continental in cast. If you should take it too seriously, you’ll lose your bearings in the real world, and you’ll go adrift in some ethereal sea of dreams.
     It is, in a word, irrelevant – right?
     Wrong, Brague writes. Sustained reflection on the nature of being, undertaken in the hope that something can indeed be said about it, was for millennia considered to be among the most important of intellectual pursuits, and not without reason. With his characteristic combination of erudition and wit, Brague takes us on a sweeping tour of the discipline’s varying fortunes, from its early Athenian practitioners through its Jewish, Muslim, and Christian heirs, to the chorus of critics who in the last few centuries succeeded in putting an end to its dominance.
     But the questions that metaphysics was asking, Brague shows, did not disappear with its demise, and so, whether implicitly or explicitly, metaphysics itself has resisted relegation to the history books. For the...
