In my house this year we are celebrating the feast of Kwanza, the African-American festival of harvest which begins the day after Christmas and lasts for seven days. There are seven principles of Kwanza, one for each day. The first principle is Umoja, which means unity, the decision to strive for and maintain unity in self and community. The principle for yesterday, the second day, was Kujichagulia—self-determination—the decision to define ourselves, name ourselves, and speak for ourselves, instead of being defined and spoken for by others. Today is the third day of Kwanza, and the principle for today is Ujima—collective work and responsibility—the decision to build and maintain ourselves and our communities together and to recognize and solve our problems together.
