Setting aside this digression, we must now address, albeit at a broad level of abstraction, the relationship between the temporality of the first historical act and the dialectic of the forces and relations of production. In other words, what is the temporal relation between the dialectic of the creation of the means to satisfy existing needs and the creation of new needs, on the one hand, and the dialectic of the forces and relations of production, on the other? The answer to this question begins with a short account of what productive forces are. Along with needs and time<sup>71</sup>, productive forces fill out Marx’s category of wealth (‘wealth’, for Marx, is a particular relation between needs, productive forces and time.<sup>72</sup>) Accordingly, the scope of a productive force is expansive. It takes in, although it is not exhausted by, what David Harvey describes as ‘the power to transform and appropriate nature through human labour.’<sup>73</sup> Productive forces encompass, but are irreducible to, the means of production [Produktionsmittel]: e.g. the tools, instruments, technologies and machineries of production (this includes, it is important to add, human bodies).<sup>74</sup> Socialised matter – both organic and inorganic matter – is a productive force, and this register informs, to take the most notable example, Marx’s extensive analyses of the relationship between land and production. Conceptually, it is important to indicate that in The German Ideology and elsewhere, forces/powers [Kräfte] should be conceived as ontologically basic to ‘means’ [Mitteln], although our understanding of the relationship between ‘productive forces’ and the broader philosophical literature on forces/powers remains largely in the dark.<sup>75</sup> It would seem, at the very least, that Marx’s ‘productive force’ is indebted to the work of Kant, Hegel and particularly Leibniz, whose internalisation of motion and force within matter points towards a necessary condition of Marx’s critical reconstruction of materialism more broadly.<sup>76</sup>
