With Anaximenes, the third great thinker of Miletus, the inquiry into the archè advances a further step toward the construction of a technical language of processes. After Thales’s visible element (water) and Anaximander’s indeterminate abstract principle (the ápeiron), Anaximenes identifies air as the primordial substance, conceiving it as a dynamic matter, capable of transformation according to measurable rules.

His fundamental contribution lies in the intuition that the transformations of reality obey gradual processes of rarefaction and condensation. Air, when compressed, becomes wind, cloud, water, earth, and ultimately stone; when expanded, it turns into fire. This vision introduces the first genuine physics of processes: becoming itself is rendered technical, the result of quantitative variations generating qualitative differences.

Here arises an extraordinary anticipation of the engineering mindset: to master nature means to understand the parameters of transformation that govern its transitions of state. Rarefaction and condensation operate as proto-algorithms, procedures allowing the calculation and prediction of matter’s behavior. The cosmos of Anaximenes thus becomes the first model in which technique is no longer confined to measurement or representation, but begins to describe mechanisms of transformation, opening the way to a manipulative and experimental conception of reality.

Anaximenes’s thought transforms the archè into a malleable matter, accessible through processes reducible to laws. It marks a further step toward a technological conception of the cosmos, wherein knowledge is configured as the art of modulating intensities, rather than the mere contemplation of essences.
