Apparently some people are ignorant, and others have forgotten,
that we have no sense that is capable of discriminating between
high and low speed, or even between motion and rest, except
by noting the usual accompaniments of motion, such as the
apparent movement of surrounding objects, the resistance of the
atmosphere, or the jolting due to obstacles in the path. If our
surroundings move with us and the motion is smooth, our methods
of detecting it fail. Thus, we can not feel the great velocity
with which the earth is moving through space. In like manner, a
train on a rough road seems to be going faster at forty miles
an hour than one on a smooth road at sixty. The sensations of
high-speed travel depend largely, therefore, on the conditions
of that travel.
In the same way our moral progress can only be measured by the
obstacles we meet and overcome.
