THE FUNDAMENTAL OXYMORON OF THERMODYNAMICS
The absurdity that entropy always increases would not hold "the
supreme position among the laws of Nature" (A. Eddington, 1935) if
Clausius had not deduced it gloriously from the fundamental oxymoron
of thermodynamics:
THE FUNDAMENTAL OXYMORON OF THERMODYNAMICS: Any irreversible process
is reversible; that is, any irreversible process can be closed by a
reversible process to become a cycle.
Any textbook author who relishes deducing the supreme absurdity should
initially introduce the fundamental oxymoron:
Peter Atkins, Physical Chemistry, 5th ed., p. 127: "Let the original
change in the entropy of the system when the process of interest
occurs be dS (this is the change we want to measure). The process need
not be reversible, but we suppose that we can find a path that joins
the same initial and final states and which is reversible."
For 140 years (Clausius deduced the supreme absurdity in 1865) the
fundamental oxymoron of thermodynamics has been questioned once:
http://philsci-archive.pitt.edu/archive/00000313/ p.39: "A more
important objection, it seems to me, is that Clausius bases his
conclusion that the entropy increases in a nicht umkehrbar
[irreversible] process on the assumption that such a process can be
closed by an umkehrbar [reversible] process to become a cycle. This is
essential for the definition of the entropy difference between the
initial and final states. But the assumption is far from obvious for a
system more complex than an ideal gas, or for states far from
equilibrium, or for processes other than the simple exchange of heat
and work."
