Rotary encourages and fosters these four principles:
FIRST. The development of acquaintance as an opportunity for service;
SECOND. High ethical standards in business and professions; the recognition of the worthiness of all useful occupations; and the dignifying of each Rotarian's occupation as an opportunity to serve society;
THIRD. The application of the ideal of service in each Rotarian's personal, business, and community life;
FOURTH. The advancement of international understanding, goodwill, and peace through a world fellowship of business and professional persons united in the ideal of service.
