Seven kinds of man are to be found in every community, seven different
points of view with regard to health administration. Each individual,
likewise, may have seven attitudes toward health laws, seven reasons
for demanding health protection. These seven points of view, seven
stages of development, are clearly marked in the evolution of sanitary
administration throughout the civilized world. With few exceptions, it
is possible, by examining ourselves, our friends, and our communities,
to see where one motive begins and leaves off, giving way to or mixing
with one or more other motives. A friend once asked me if I could keep
this number seven from growing to eight or nine. Perhaps not. Perhaps
there are more kinds of people, more health motives, more stages in
health progress; but I am sure of these seven, and certain that they
have been of great help to me in planning health crusades for the state
of New Jersey and for New York City. The number seven was not reached
hit-or-miss fashion, nor was it chosen for its biblical prestige. On
the contrary, it came as the result of studying health administration
in twoscore British and American cities, and of reading scores of books
on sanitary evolution.

Seven catchwords make it easy to remember the characteristics and the
source of every motive, every kind of person, and every stage in the
evolution of sanitary standards. These seven catchwords are:
_Instinct_, _Display_, _Commerce_, _Anti-nuisance_, _Anti-slum_,
_Pro-slum_, _Rights_. By the use of these catchwords any teacher,
parent, public official, educator, or social worker should be able to
size up the situation, the needs, and the opportunity of the
individuals or the communities for whom a health crusade is planned.

_Instinct_ was the first health officer and made the first health laws.
Instinct warns us against unusual and offensive odors, sights, and
noises, just as it causes us to seek that which is agreeable. Primitive
man in common with other animals learned by sad experience to avoid
certain herbs as poisons; to bury or to move away from the dead; to
shun discolored drinking water. During the roaming period sun and air
and water acted as scavengers. When tribes settled down in one spot for
long periods, habits that had hitherto been inoffensive and safe became
noticeably injurious and unpleasant. Heads of tribes gave orders
prohibiting such habits and restricting disagreeable a
