I posted this once before, I believe. I think it is a valid definition
for any cultural identity, Celtic or otherwise. Of course, that is only
my opinion. You are welcome to disagree.
In sociology and anthropology, the way of life of a particular
society or group of people, including patterns of thought,
beliefs, behavior, customs, traditions, rituals, dress, and
language, as well as art, music, and literature. Culture is
key to describing and analyzing human societies.
