same
with a loaded gun. The expression of motion in terms of its opposite
rest presents no difficulty at all to the dialectic philosophy. The
whole contradiction in its eyes is merely relative, for absolute
rest, complete equipose does not exist. The movement of the particles
strives towards equipose, the movement of the mass in turn destroys
the equipose, so that rest and equipose where they occur are the
results of arrested motion, and it is evident that this motion is
capable of being measured in respect of its results, of being
expressed in itself and of being restored in some form or other
external to itself. But Herr Duehring would never be satisfied with
such a simple explanation of the matter. Like a good metaphysician he
creates a yawning gulf between motion and equipose which does not
really exist and then wonders if he can find no bridge across the
self-created chasm. He might just as well bestride his metaphysical
Rosinante and hunt the "Ding an Sich" of Kant since it is in the last
analysis nothing else than this which stands behind the undiscoverable
bridge.

But what about the mechanical theory of heat and of latent heat which
is a "stumbling block" in the path of the theory?

If one convert a pound of ice at freezing point under normal
atmospheric pressure into a pound of water of the same temperature by
means of heat there vanishes a quantity of heat which could heat the
same pound of water from 0 deg. centigrade to 79 deg. centigrade, or
seventy-nine pounds of water one degree centigrade. If one heat this
pound of water to boiling point, that is, to one hundred degrees
centigrade and change it into steam of the heat of one hundred degrees
centigrade there vanishes up to the time when the last of the water is
changed into steam a seven fold greater quantity of heat, capable of
raising the temperature of 537.2 pounds of water one degree. This
dissipated heat is called latent. It is transformed, by cooling the
steam, into water again, and the water into ice, so the same mass of
heat which was formerly latent, is again set free, that is, as heat
capable of being felt and measured. This setting free of heat by the
condensation of steam and the freezing of water is the reason that
steam if it is cooled off at 100 deg. transforms itself little by little
into water, and that a mass of water at freezing point is but slowly
transformed into ice. These are the facts. The question is what
becomes of the heat w
