I understand the concern regarding the limits of conceptual systems, especially in thinkers such as Wittgenstein or Heidegger, or in traditions which emphasise silence before what exceeds discursive articulation. But I am not convinced that this therefore entails abandoning systematic philosophy altogether.
For even the recognition of conceptual limitation, ineffability, or the withdrawal of Being still appears to occur through intelligible structures of judgment, distinction, inference, and relation. In that sense, critique itself seems unable to entirely escape the conditions of rational intelligibility it questions.
At the same time, I recognise that we are still articulating all of this through human cognition itself. But perhaps transcendental inquiry does not attempt to step outside cognition altogether. Rather, it asks what structures already appear unavoidable within the very possibility of intelligible thought, judgment, or questioning as such.
The deeper difficulty, then, may not simply concern whether transcendental structure is dependent upon cognition or independent from it, but whether the recognition of such structure is ever possible without already being mediated through cognition itself.
Yet even this recognition still seems to presuppose determinate intelligibility through relation, distinction, and inferential structure. And for that reason, I am not sure systematic philosophy is merely optional. Without some attempt at coherent structural integration, thought risks collapsing into fragmentation, arbitrariness, or isolated intuition lacking justificatory unity.
So perhaps the issue is not whether systematic philosophy should be abandoned, but whether it can become sufficiently reflexive to account for its own conditions and limits without undermining the intelligibility of critique itself.
