In a line that appears only once among the thousand or so pages in Kant's epoch-defining Critique of Pure Reason, Kant makes mention of a 'system of the epigenesis of pure reason'. A single phrase, never repeated. Yet it is upon this line - and the profusion of scholarship it has inspired - that Malabou will hang nothing less than the fate of thought itself, a fate tied irrevocably and irreducibly to the fate of the transcendental. Which means what exactly? Some backstory: for Kant, our very ability to think is tied to the possibility of applying the 'categories' of our understanding to the objects of our experience: no application of categories, no thought. So far, so good. But whence do the categories themselves arise, and what, exactly, guarantees the necessity of their application? Why, a system of the epigenesis of pure reason of course. And what, exactly, is that? Well, it's the effort to answer this question that defines the particular and magnificent adventure undertaken by Malabou's Before Tomorrow.
But why the 'fate of thought'? Isn't that a bit grand? Surely this is Kantian arcana, made for the back-alleys of academic journals and squirrelled-away conferences? Perhaps. But the twist is in the peculiar 'status' of the categories, one strictly specified by Kant to make all the difference: the categories, for Kant, are 'transcendental', which is to say - they cannot be derived from experience; indeed, they condition the possibility of experience to begin with. Now, if you're still with me, here's the kicker: at stake in all of this is the need for Kant to avoid the arbitrariness of the agreement between the categories and its objects. Such an arbitrary agreement would lead right down the rabbit hole of skepticism, in which thought would not reflect, at it were, the true nature of the world. Against this, Kant's whole enterprise will be to insist upon the necessity of the categories and their 'agreement' with objects, of their non-arbitrary and 'non-empirical' status: in short, their transcendental nature. Nothing other than this transcendental necessity defines, after all, the very impetus behind the critical philosophy.
But exactly how to conceptualise this necessity is the question which haunts the Kantian project, and, in Malabou's retelling, has been nothing less than the spindle upon which modern philosophy itself continues to turn. Thus from Kant to Heidegger, Foucault to Meillassoux (who, by the way, gets a right ribbing all throughout this book), Malabou takes it upon herself to chart the destiny of the transcendental though its many modifications, and ultimately, through the many attempts made to 'relinquish' it in one way or another. In the narrative so told, contemporary philosophy today finds itself at a crossroads: to be done with the transcendental, to relinquish it once and for all, or to rethink it so as to defend its legacy and extend it along paths yet unexplored. If it isn't obvious by now, it's this latter route which is chosen by Malabou, who, in taking seriously Kant's brief mention of the 'system of epigenesis of pure reason' in the first Critique, aims to set the transcendental on a new footing, grounded in - of all things - the vivacity of life itself.
Indeed, it's in the recourse to 'life' - life in its properly fleshly, biological register - that Malabou stakes her reading of the transcendental, finding in the 'purposiveness' of the biological the key through which to unlock the enigma of the 'system of the epigenesis...'. While I can only barely scratch the surface of the moves made in support of her particular position, suffice to say that its implications bear upon almost the entire terrain of the classical philosophical landscape - on the relation between necessity and contingency; on the need rethink 'finitude' on the basis of 'life' rather than 'existence' (Malabou's anti-phenomenological dig); on the necessity of rethinking history, time, and meaning on the basis of an 'epigenesis' rather than a 'genesis' (a distinction fleshed out in detail in the book); on the need to re-evaluate the relationship between philosophy and science (an ongoing project of all Malabou's writings); these, of course, and so much more. While it's true that this book itself only lays out the rudiments of what seems to me to be a wider, as-yet-unrealized project (cf. Malabou's recent work on biology and the symbolic), Before Tomorrow nonetheless remains a stunning achievement which demands to be read by anyone with an interest in... well, tomorrow.
