Cambridge English Dictionary states that culture is, "the way of life, especially the general customs and beliefs, of a particular group of people at a particular time." Terror Management Theory posits that culture is a series of activities and worldviews that provide humans with the illusion of being individuals of value in a world meaning—raising themselves above the merely physical aspects of existence, in order to deny the animal insignificance and death that Homo Sapiens became aware of when they acquired a larger brain.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): What is the name of this theory that culture is a series of activities and world views?
