What is "regressus"

Usage examples of "regressus".

An insoluble problem, it seemed, a regressus ad infinitum: One could devise a system to monitor a monitoring system, but that system itself would be vulnerable to attack, so one would have to monitor the monitor of the monitor, and so on, without end.

The same applies to the series of causes, one being prior to the other, and to the series leading from conditioned to unconditioned necessary existence, which can never be regarded either by itself finite in its totality or infinite, because, as a series of subordinated representations, it forms a dynamical regressus only, and cannot exist prior to it, by itself, as a self-subsistent series of things.
