greater the interdependence of the individuals, the more complex the
government.

Confining our attention now to man, whose government is the most complex,
we may put our generalization into this form: Man establishes government
because _by nature he is a social being_. This may be taken as the
fundamental reason. Let us now proceed to trace the relation between cause
and effect.

In order that people may go from place to place to meet others for
pleasure or business, roads are needed. Some of these roads may cross
streams too deep for fording, so bridges must be provided. These things
are for the good of all; they are public needs, and should be provided by
the public. But "what is every body's business is nobody's business." It

things. By the act of appointing these persons, society becomes to that
extent organized. We see, then, that society organizes in order to provide
certain public improvements, _to carry on certain public works_.

For his own preservation, man is endowed with another quality, namely,

Communities take their character from that of the individuals composing
