Not only would the skill and speed demanded by modern industry be
impossible without the aid of habit, but without its help none could
stand the fatigue and strain. The new workman placed at a high-speed
machine is ready to fall from weariness at the end of his first day. But
little by little he learns to omit the unnecessary movements, the
necessary movements become easier and more automatic through habit, and
he finds the work easier. We may conclude, then, that not only do
consciously directed movements show less skill than the same movements
made automatic by habit, but they also require more effort and produce
greater fatigue.

Kant asserted that the processes of combination of surrounding

cold materials would generate heat, and, therefore, that the
resulting planetary masses would assume the liquid form; that
Jupiter and Saturn are now in the liquid state; and that all
the planets will ultimately become cold and solid
Kant asserted that the processes of combination of surrounding
cold materials would generate heat, and, therefore, that the
resulting planetary masses would assume the liquid form; that
Jupiter and Saturn are now in the liquid state; and that all
the planets will ultimately become cold and solid. This is in
fair agreement with present-day opinion as to the planets, save
that modern astronomers go further in holding that the outer
strata of Jupiter and Saturn, likewise of Uranus and Neptune,
down to a great depth, must still be gaseous. In 1785, after
the principle of heat liberation attending the compression of a
gas had been announced, Kant supplemented his statement of 1755
as to the origin of the Sun"s heat. He attributed this to
gravitational action of the Sun upon its own matter, causing it
to contract in size: he said the quantity of heat generated in
a given time would be a function of the Sun"s volumes at the
beginning and at the ending of that period of time. This is
substantially the principle which Helmholtz rediscovered and
announced in 1854, and which is now universally accepted--with
the reservation of the past ten years, that radioactive
substances in the Sun may be an additional factor in the
problem.

II.--In the Psychology of Ethics, he regards the Conscience as a
derived or generated faculty, the result of a series of associations.
He assigns the primary feelings that enter into it, and traces the
different stages of the growth. The distinctive feature of Conscience
is its close relation to the Will.
