But, Sigma Nu's definition is straightforward. 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.
