It has to do with the lifestyle of the Legion of Honor which relates specifically to the mission and purpose of the Fraternity. And Sigma Nu doesn't mince words about its rasion d'etre . Brotherhood means responsibility. The man who instead stands tall by fulfilling commitments to parents, alma mater, Sigma Nu, and by making his grades, paying his fair share of costs, and contributing his fair share of time and talent to the Chapter, justly earns himself the label of Brother in the Legion of Honor. Central to the Brotherhood concept is the commitment not only to do a thing right but to do the right thing .
Brotherhood means selflessness.
Caring enough for the common good of the whole chapter for all the right and honorable reasons defines Sigma Nu Brotherhood at its best. Brotherhood means sportsmanship. In Sigma Nu, there is no need, no room, and no use for the unsportsmanlike, the apathetic, the indifferent, the lazy, the prima donna . Deliberate foul play, whether in sports or in any other chapter activity or at any other time has no place in Sigma Nu. Fair play, cooperation, motivation, living up to rules and polices, giving credit where credit is earned, being a self starter and remaining self-reliant are characteristics of a genuine Brotherhood.
