Title / Titel Vis veritatis – Kepler’s criteria of truth
PDF Abstract (PDF, 14 KB)
Summary / Zusammenfassung Johannes Kepler intensified the discussion about the status of astronomical hypotheses as mathematically fruitful fictions or as true descriptions of reality.
At the beginning of the 17th century there were at least two empirically equivalent but contradictory theories about the forma mundi: the Copernican and the Ptolemaic. Given that an astronomical hypothesis is able to describe reality in a true form, it is evident that only one of several contradictory but empirically equivalent theories can be true. The possible criteria to decide which one of them is true must be non-empirical.
The aim of my thesis is to portray Kepler’s non-empirical criteria of truth in natural science.
I assume that Kepler’s theological and philosophical criteria of truth led towards the development of modern physical astronomy and closer to the now existing gap between natural sciences and humanities.
