A difference exists in a relation. What has been distinguished acquires definiteness within a relation, and the act of distinction is performed by a subject in their relation to reality. The subject of this investigation is the connection between relation, the act of distinction, and the definiteness emerging within it.
Difference and the Sides Distinguished
The statement “A differs from B” already establishes a relation. If everything relative to which something is distinguished is eliminated, the definite content of the difference itself disappears. A distinguished side does not necessarily have a name or an explanation: the subject is capable of discovering a difference without yet knowing the nature of what was discovered.
Two ready-made objects are not necessary prerequisites for the act. Singling them out already presupposes distinction. Therefore, explaining every distinction through a connection between previously defined objects would use its own result as its initial condition.
The subject is necessary for the act of distinction: in this act, a definite “what” appears to which the subject can turn. The phrase “without a subject, there is nothing to distinguish” expresses the absence of an already singled-out subject matter of distinction. The question of whether the whole of reality originates from the subject is neither resolved by this proposition nor part of its content.
Reality and the Possibility of Further Distinction
Reality is the space of the inexhaustible possibility of distinction. No distinction already drawn exhausts the possibility of further distinction. The expression that differences “tend toward infinity in the limit” expresses this inexhaustibility; it does not provide a mathematical count of ready-made differences.
A definite boundary arises in the subject’s relation to what is happening. Subsequent distinguishing can reveal what the earlier boundary combined or overlooked. Reality is not obliged to be divided in advance into the units of an accepted description. The example of qualification levels shows how two, three, or many levels can organize the consideration of an activity.
Holding a definite boundary over time connects this understanding of reality with form. The possibility of returning to a boundary is compatible with discovering its limitations and revising it.
Several Meanings of Relation
Physical interaction, measurement, and a subject’s relation to what is happening have different structures. A body accelerates under the action of a force; a researcher compares measured force and acceleration; a subject chooses which behavior of the body to consider significant and which question to ask about it. All three cases are connected, but one cannot replace one with another without proof.
A relation in the form “A is connected with B” already presupposes that A and B have been distinguished. If it is said to generate every distinction, a circle arises: the terms of the relation must be given before they themselves emerge. But a more primary meaning of the word is possible: an encounter or being-in-relation in which the sides have not yet been determined as ready-made objects. Distinction then singles out “this / not this” within what is happening, while a formulation of the connection between A and B appears later. Here “before” means a logical condition for consideration, not necessarily an earlier moment in time.
This approach preserves the primacy of the act of distinction: that act remains the first step in which definite sides are established for the subject. The subject’s relation to reality is a condition for the act here; connections between already distinguished objects become available for further consideration.
In this sense, the act of distinction can be understood as the enactment of a subject’s relation to reality: within it, the subject encounters what is happening and singles out “this / not this.” But “subject” and “reality” are names introduced in the subsequent description of the act. One cannot imperceptibly substitute for the initial encounter two sides that have already been defined within that encounter.
Mass as an Example of Determination in a Relation
In classical mechanics, Newton’s second law is written as \(F_{\text{res}} = ma\): the resultant force and the body’s acceleration are connected through its inertial mass. To determine mass in this way, it is necessary to establish which body is measured, specify a frame of reference, determine the resultant force, and measure acceleration. With nonzero acceleration and within the conditions in which the model applies, the relation \(F_{\text{res}}/a\) yields a mass value.
The formula shows that a mass value is established not merely by looking at an isolated body, but through reproducible measurement of its dynamic response. Yet the method of measurement does not imply that the body only acquires inertia when it meets a device or researcher. If it shows a stable response in comparable conditions, this limits the possible measurement values. It is necessary to distinguish the body’s physical capacity, the procedure for determining it, and the numerical value recorded.
The mass example supports the thesis concerning relation as a condition for definiteness accessible to us. The stronger thesis that mass itself exists only as a relation requires a separate argument. The equality \(F_{\text{res}} = ma\) does not in itself prove it.
Difference as the Result of Relating
Even the simple “this differs from that” presupposes a way of relating what is distinguished. It may include adjacency, sequence, comparison with memory, effects on the body, or a question directed at what is happening. However, not every act begins by comparing two already known things. In the act “this / not this,” the sides themselves become definite through the boundary drawn.
Memory preserves traces of distinctions already drawn, to which the subject can return and which the subject can relate to one another. The subject notices their similarity, incompatibility, transition, or common boundary and obtains a new distinction not present in either one separately. Further investigation can relate the result again to other distinctions. This produces a recurring movement:
first distinction → trace in memory → drawing a boundary anew → relating → next distinction
This sequence explains the formation of subsequent distinctions. It must not replace the question about the first act with the claim that two ready-made distinctions already existed beforehand. At the initial level, the issue is the subject’s relation to what is happening; at the next, relations between what has already been distinguished.
Memory allows the subject to return later to what was discovered. “Trace” in this sequence denotes a connection to the previous act, not a ready-made explanation of what exists between acts. On returning, the subject performs a new act and may again draw a recognizable boundary. The research thesis of form as the process of holding a distinction raises the question of this boundary’s continuation over time. What makes it possible to establish its connection to the previous boundary, and how preserving a distinction relates to the possibility of drawing it anew, are examined in “Memory and the Holding of Form”.
Three propositions are connected here:
- Difference is definite in a relation: what has been distinguished becomes definite relative to that from which it differs.
- The act of distinction presupposes a subject: the subject performs a distinction in relation to reality; this relation may be sensory and need not have a ready-made explanation.
- Further distinguishing rests on what has already been distinguished: relating held distinctions may yield a new distinction.
Relation in the first proposition is not necessarily the result of conscious comparison. The subject may hear a change in sound before naming the sides being compared or explaining what occurred. Sensory distinction examines this case.
What Changes in the Investigation
The definiteness of a property includes the relation in which it is discovered. In the mass example, the body’s response, the experimental procedure, and the numerical result are connected. In activity, outwardly identical actions acquire different meanings depending on the relation enacted by the subject.
The general thesis that difference exists in relation leaves the structure of particular relations open. Sensory discovery of a change, measurement, and the introduction of a category yield different ways of establishing definiteness; their connection becomes an independent subject of investigation.
What Requires Examination
- Relation and subject. The necessity of a subject for the act of distinction is established in the accepted definition of the act. What requires separate examination is the sense in which one can speak of relations without distinction performed by a subject.
- Universal interconnectedness. The formulation “everything influences everything simultaneously” has been put forward as a research direction. It has not yet been established whether this means a direct influence of every change on everything else or the impossibility of fully isolating a distinguished phenomenon from the relations of its existence. The meaning of “simultaneously” also requires clarification. The inexhaustibility of distinction in itself establishes neither of these assertions.
- Definiteness and arbitrariness. The possibility of different ways of division raises the question of how the relation to the task and what is happening participate in drawing a particular boundary. The case of qualification levels examines this question without supposing that a unique number of categories is specified by reality in advance.
