The categories of the second class (those of causality and of the necessity of a thing) did not require this homogeneity (of the conditioned and the condition in synthesis), since here what we have to explain is not how the intuition is compounded from a manifold in it, but only how the existence of the conditioned object corresponding to it is added to the existence of the condition (added, namely, in the understanding as connected therewith); and in that case it was allowable to suppose in the supersensible world the unconditioned antecedent to the altogether conditioned in the world of sense (both as regards the causal connection and the contingent existence of things themselves), although this unconditioned remained indeterminate, and to make the synthesis transcendent.
Bigarren motako kategoriek (gauza baten kausalitatearenak eta beharrezkotasunarenak) ez dute eskatzen erabatekotasun hori inolaz ere (baldintzatua dena eta baldintzarena sintesian), zeren hemen ez baita begiespena errepresentatu behar, anitza denetik nola osatzen den erakutsiz, baizik eta hari dagokion objektu baldintzatuaren existentzia nola gaineratzen zaion baldintzaren existentziari (adimenean harekin elkarlotuta), eta han baimendua zegoen sentsuen munduan erabat baldintzatua denari (bai kausalitateari dagokionez baita gauzen ausazko izateari dagokionez ere) baldintzatugabea ezartzea mundu adimenduzkoan, modu determinatugabean bada ere, eta horrela sintesia transzendente bihurtzea;
