Materialism is a philosophical viewpoint asserting that physical matter is the only or primary reality. It posits that everything, including thoughts, feelings, and consciousness, can be explained in terms of material interactions. This perspective contrasts with idealism, which emphasizes the primacy of the mind or spirit. In the context of economics and culture, materialism often refers to a preoccupation with material possessions and physical comfort. This consumerist attitude can lead to the belief that happiness and fulfillment are derived from acquiring goods, rather than from relationships or experiences.
