I'm reading on Kwanzaa, an African American holiday for the winter solstice which has been criticized severely by some people in the Xtian Reich (most notably Ann Coulter and Fox News) because they fear that it is intended to replace Christmas. Either way, I was reading about the seven principles that Kwanzaa celebrates and their ethical meanings and was quite inspired by them. 'Faith' might be interpreted as a religious principle, but then again one of the three candles that are lit for Humanlight, the Humanist solstice celebration, is for 'Hope' which is sort of the same thing - the idea being that since this is the longest night of year we know that the sun will shine again and spring will return.
Otherwise, the message of Kwanzaa promotes relationships between equals, cooperation, respect for elders, having goals and planning for the future, cultivation of the arts and creativity. It's a pretty wholesome set of principles and it's pretty much in line with humanist values because it is critical of economic exploitation and the commercialization of the holidays and there's absolutely no reference to the supernatural.
