perfect right that matters would stand otherwise if through a
number of generations women and men were educated equally, and trained
in the exercise of those arts and of mental discipline. On an average,
woman is also weaker than man, which is by no means the case with many
wild peoples.[140] What exercise and training from early youth are able
to change in this matter, we may see in the circus women and female
acrobats, who in courage, foolhardiness, dexterity and physical strength
achieve marvelous feats.

Seeing that such a development is a matter of the conditions of life and
education--or, to express it in the naked language of science, of
"breeding"--it may be taken for certain that the application of these
laws to the physical and mental life of man would lead to the most
brilliant results, _the moment man sets his hand to the work with full
consciousness of his object and his aim_.

As plants and animals depend upon the conditions for existence that they
live under--promoted by favorable, checked by unfavorable ones--and as
forcible conditions compel them to change their appearance and
character, provided such conditions are not unfavorable enough to
destroy them wholly, so it is with man. The manner in which a person
makes his living influences not his external appearance only, it
influences also his feelings, his thoughts and his actions.[141] If,
accordingly, man's unfavorable conditions of life--defective social
conditions--are the cause of defective individual development, it
follows that _by changing his condition of life, man is himself
changed_. The question, therefore, is so to change the social conditions
that every human being shall be afforded the possibility for the full
and unhampered development of his being; that the laws of evolution and
adaptation, designated after Darwin as "Darwinian," be consciously
rendered effective to humanity. But this is possible only under
Socialism.

As a thinking and intelligent being, _man must constantly, and conscious
of his purpose, change, improve and perfect his social conditions,
together with all that thereby hangs; and he must so proceed in this
that equally favorable opportunities be open to all_. Every individual
must be placed in a position to be able to develop his abilities and
faculties to his own as well as to the advantage of the collectivity;
but his may not be the power to injure either others or the
collectivity. His own and the advantage of o
