 Thus, the main goal of 1877b is apparently to address the problem concerning evolutions and to show how they relate to the Second Law. Indeed, this is what one would naturally expect since the reversibility objection is, after all, a problem concerned with evolutions. Even so, a remarkable fact is that the 1877b paper hardly ever touches its self-professed “main goal” at all.  For a sketch of how different commentators on Boltzmann's (1877b) view his attitude on this question I refer to Uffink (2007).
