When Johannes Kepler was formulating his eponymous laws of planetary motion (17th century Astronomia nova, Harmonices Mundi) there was no clear distinction between astronomy and astrology. But there was a strong division between astronomy (a branch of mathematics within the liberal arts) and physics (a branch of the more prestigious discipline of natural philosophy). Kepler also had a religious conviction that God had created the world according to an intelligible plan that is accessible through the natural light of reason.
In the 21st century old pharts will be arguing cybernautical vs cybernetical. Its relevance to the real world? Just as relevant as the perihelion and the apohelion.
