The transitions are not interchangeable
Explaining how something can exist is not equivalent to showing how it is realized, expressed, or criticized.
Dynamics of the system
A determination does not remain identical as it passes through reality, action, exposition, and reflection: at each transition, the problem it must solve changes
Movement
Viewing the same object from different points of view may leave what is observed unchanged. Here something stronger occurs: the passage from a form to its realization, from realization to exposition, and from exposition to reflexive scrutiny changes the very status of the determination.
A possibility becomes practice; a practice acquires a language; a language produces effects; and the analysis of those effects forces a revision of the initial possibility. The path does not merely add information; it retroactively transforms what it began from.
Relations
Explaining how something can exist is not equivalent to showing how it is realized, expressed, or criticized.
Practical or linguistic consequences may reveal that the initial determination was too poor or built upon a hidden exclusion.
Reflection returns to the point of departure with a more determinate understanding, while leaving open the possibility of further correction.
Error
A theory may define a form precisely yet fail to explain how it enters experience. It may describe a practice and ignore the language that legitimates it. It may analyze a discourse and forget the material conditions that sustain its effectiveness.
Skipping a transition produces an illusion of completeness: what has only been presupposed appears as though it had already been demonstrated. Following the movement helps locate these gaps and prevents one phase from speaking on behalf of the others.
Example
At first, a promise may be defined as a commitment. Once uttered, however, it depends on an addressee, linguistic conventions, and the speaker’s credibility. When it guides conduct, it enters relations of trust, power, and responsibility.
The final scrutiny may show that the initial definition was insufficient: an extorted promise retains the verbal form of commitment but compromises its conditions. The object has not merely been observed several times; it has been more fully determined.
Figure
A non-linear figure makes visible that no direction is simply external to the others. Each vertex acquires meaning through its connections, and every return traverses the entire structure.
The representation nevertheless remains heuristic: it shows simultaneity and connection, but it does not demonstrate the philosophical necessity of the transitions. Demonstration belongs to argument, not to the drawing.
