Positing of presuppositions

Positing of presuppositions describes how a subject can become responsible for conditions that were never established by a single, consciously chosen act. Rather than discovering a prior moment of sovereign freedom, the subject retrospectively assumes authorship of a framework already shaping experience. The book places this paradox within a wider account of parallax: limits and oppositions need not be reconciled by a higher, external unity, because their constitutive tension can itself disclose the structure at issue.

Retroactive Responsibility

In the discussion of freedom, the phrase names the Hegelian weight of retroactivity. There is no empirical founding act in which a subject steps outside every prior condition and freely creates a basic framework. Instead, responsibility emerges gradually: at a certain point, the subject recognizes that he or she already was responsible. The comparison is to a scattered collection of grains that becomes a heap without any one grain being identifiable as the decisive one. Looking back, one can point to an earlier stage and say that the heap had already formed, even though no single addition created it.

The same retrospective logic applies to a “Primary Mammal.” Physical reality contains no first mammal that can be isolated as the beginning of the species, yet reference to one is necessary at the design level. This is not a claim that an ideal or mental process reaches downward and breaks the causal chain of physical events. Freedom instead names a reflexive, transitive causality: a causality that determines which causality will determine the subject. The act is not a supernatural interruption of mechanism but a way of taking responsibility for the determining framework.

This account also distinguishes responsibility from a simple assertion of conscious mastery. A subject does not first possess complete knowledge of the conditions and then choose them from a position outside them. The framework is already operative; the subject’s freedom takes the form of assuming it as one’s own. The paradox is that what was never an empirical act must nevertheless be presupposed as an act of the subject.

The Kantian Subject and the Hegelian Shift

The subject who assumes such responsibility is not a substantial self transparently present to itself. Kantian self-consciousness is described as more than a fragmentary awareness of changing mental states, but less than direct knowledge of an enduring identity. It is a logical point of reference required to stand for whatever has attitudes, desires, and judgments. Its necessity arises not from an inner theater of direct self-acquaintance but from the absence of one: the subject is not directly accessible to itself.

This problem echoes the book’s account of the passage from Kant to Hegel. Kant treats the gap between knowledge and the thing-in-itself as an epistemological limit, which can leave the inaccessible realm appearing fully constituted beyond that limit. Georg Wilhelm Friedrich Hegel’s move is not simply to close the gap or restore a pre-critical metaphysics. He treats negativity and incompleteness as features of reality itself. The limit is no longer merely an obstacle between the subject and an independently complete object; it belongs to the object’s own constitution.

On this account, positing presuppositions does not mean escaping a division by discovering a final standpoint beyond it. The division can be affirmed as such. A formal shift in perspective reveals that the demand to overcome the opposition was itself part of the problem: recognizing the opposition’s constitutive role can perform the reconciliation that an additional synthesis was supposed to supply. The expression thus belongs to a broader reversal in which a limitation is not merely removed but understood as a positive condition.

Parallax, Exception, and Historical Form

The book extends this logic through the idea of concrete universality. A universal category may fail to contain the elements gathered under it; those elements can resist or exceed its frame. The resulting distance is not simply an imperfection to be corrected. The exception that has no proper place in the structure can, in the relevant sense, stand for the universal dimension itself. Conversely, the element that appears to fit the universal directly may be its true exception. Universality is encountered in this constitutive mismatch, not as a neutral container placed above particulars.

A related tension appears in the account of historical development. Different domains can actualize the same underlying principle without doing so at the same historical moment. The example is the modern principle of subjectivity, expressed differently in religion, ethics, and politics. These expressions do not line up as simultaneous copies of a single essence; their temporal displacement is part of the historical structure. The phrase’s retroactive logic is compatible with this temporal parallax: what counts as a presupposition, or as the organizing principle of a process, becomes legible through relations that are not all present at once.

Marx, Value, and the Necessity of Form

The book applies a comparable parallax reading to Karl Marx. In Marx’s treatment of value, production and circulation cannot be reduced to one another. Value has to originate outside circulation, in production, and in circulation; the opposed positions form an antinomy rather than a choice between one true site and one merely illusory one. Later versions of Marxism, both Social Democratic and Communist, are criticized for losing this perspective and elevating production as the sole site of truth against exchange and consumption.

The analysis of money sharpens the point. Mercantilists treat money as a special thing with inherent power. Classical political economy, represented by David Ricardo, rejects that fetishistic belief but locates value as a substantive property of the commodity, expressed by money as a sign of socially useful labor. Neoclassical economics, by contrast, rejects a substantial value and understands price through relations of supply and demand. The book emphasizes how Marx’s engagement with Bailey’s relational account of value helps him move beyond the opposition between money as an inherently special object and value as an inherent substance. A commodity becomes money by occupying the formal place of the general equivalent, not because gold is naturally money.

A wooden table makes the difference between material object and commodity form visible. As a useful object, it remains wood shaped for human use. Once it enters commodity relations, it takes on a transcendent social character, standing in relation to other commodities and appearing to possess a power beyond its material usefulness. The commodity’s mystification does not originate simply in its physical substance or in useful labor. It depends on the social form assumed when people work for one another.

For this reason, Marx’s critical task is not merely to pierce appearance and uncover a hidden essence beneath it. The form itself is essential: reducing it to a “mere form” misses the way the secret depends on that form. Positing presuppositions, read through this wider argument, helps name a method of attending to the conditions that make a reality possible without treating those conditions as an external, complete foundation. The apparent obstacle, gap, or formal mediation is not disposable residue; it may be where the structure becomes legible.
