Interesting, I didn't know there was such a thing (despite having read quite a lot of Ortega y Gasset).
Compare this with paradigm shifts in T. S. Kuhns The structure of scientific revolutions:

Strongly recommend The Structure of Scientific Revolutions - I actually think it ties a bow pretty neatly between the Ortega and Newton hypotheses.
