  We present an English translation of Erwin Schr\"odinger's paper on "On the
Reversal of the Laws of Nature". In this paper Schr\"odinger analyses the idea
of time reversal of a diffusion process. Schr\"odinger's paper acted as a
prominent source of inspiration for the works of Bernstein on reciprocal
processes and of Kolmogorov on time reversal properties of Markov processes and
detailed balance. The ideas outlined by Schr\"odinger also inspired the
development of probabilistic interpretations of quantum mechanics by F\'enyes,
Nelson and others as well as the notion of "Euclidean Quantum Mechanics" as
probabilistic analogue of quantization. In the second part of the paper
Schr\"odinger discusses the relation between time reversal and statistical laws
of physics. We emphasize in our commentary the relevance of Schr\"odinger's
intuitions for contemporary developments in statistical nano-physics.
