If one were to examine the mottos and crests of each organization, he or she would notice striking similarities between each of the crests, rather the similarities be the elements of the shields or similarities in mottos. The answer is simple. People have different ways of achieving their goals. Each fraternity and sorority has its own mottos, passwords and handshakes. But, just as cars are designed differently, they are all used for transportation.
People are the same way.
If one studies Physics or English, the goal is to receive a degree of some sort. Fraternities and sororities are the same way. Each of the organizations propose different methods as to how we could improve our communities, but in each, the goal is to improve the quality of life for everyone. Most of the fraternities' and sororities' governing bodies were started in the early 1900s. The National Panhellenic Conference, founded in 1902, is an umbrella organization for 26 international women's fraternities and sororities.
