There are marked advantages in starting the evolution of the

solar system from a spiral nebula, aside from the fact that
spirals are abundant, and therefore represent a standard
product of development
There are marked advantages in starting the evolution of the
solar system from a spiral nebula, aside from the fact that
spirals are abundant, and therefore represent a standard
product of development. The material is thinly and very
irregularly distributed in a plane passing through the Sun, and
the motions around the Sun are all in the same direction. The
great difficulty in the Laplace hypothesis, as to the constancy
of the moment of momentum, is here eliminated. There are
well-defined condensations of nuclei at quite different
distances from the Sun. According to this hypothesis the
principal nuclei are the beginnings of the future planets. They
draw into themselves the materials with which they come in
contact by virtue of the crossings of the orbits of various
sizes and various eccentricities. The growth of the planets is
gradual, for the sweeping up and combining process must be
excessively slow. The satellites are started from those smaller
nuclei which happen to be moving with just the right speeds not
to escape entirely the attractions of the principal nuclei, nor
to fall into them. The planes of the planetary orbits and, in
general, the planes of the satellite orbits should agree quite
closely with each other, but they could differ and should
differ from that of the Sun"s equator.

Doubtless the attitude toward the victims of commercialized vice will be

modified by many reactions upon the public consciousness, through a
thousand manifestations of the great democratic movement which is
developing all about us
Doubtless the attitude toward the victims of commercialized vice will be
modified by many reactions upon the public consciousness, through a
thousand manifestations of the great democratic movement which is
developing all about us. Certainly we are safe in predicting that when
the solidarity of human interest is actually realized, it will become
unthinkable that one class of human beings should be sacrificed to the
supposed needs of another; when the rights of human life have
successfully asserted themselves in contrast to the rights of property,
it will become impossible to sell the young and heedless into
degradation. An age marked by its vigorous protests against slavery and
class tyranny, will not continue to ignore the multitudes of women who
are held in literal bondage; nor will an age characterized by a new
tenderness for the losers in life"s race, always persist in denying
forgiveness to the woman who has lost all. A voice which has come across
the centuries, filled with pity for her who has 'sinned much,' must at
last be joined by the forgiving voices of others, to whom it has been
revealed that it is hardness of heart which has ever thwarted the divine
purposes of religion. A generation which has gone through so many
successive revolts against commercial aggression and lawlessness, will
at last lead one more revolt on behalf of the young girls who are the
victims of the basest and vilest commercialism. As that consciousness of
human suffering, which already hangs like a black cloud over thousands
of our more sensitive contemporaries, increases in poignancy, it must
finally include the women who for so many generations have received
neither pity nor consideration; as the sense of justice fast widens to
encircle all human relations, it must at length reach the women who have
so long been judged without a hearing.

THE LAW OF RECENCY

THE LAW OF RECENCY.--We may state the law of recency in physiological
terms as follows: The _more recently_ brain centers have been employed
in a certain activity, the more easily are they thrown into the same
activity. This, on the mental side, means: The more recently any facts
have been present in consciousness the more easily are they recalled. It
is in obedience to this law that we want to rehearse a difficult lesson
just before the recitation hour, or cram immediately before an
examination. The working of this law also explains the tendency of all
memories to fade out as the years pass by.
