What is the idea that everything is material and nothing is spiritual?

The idea that everything is material and nothing is spiritual is known as materialism. This philosophical viewpoint asserts that only physical matter exists, and all phenomena, including consciousness and thoughts, can be explained through interactions of matter. Consequently, it rejects the existence of any spiritual or non-material entities, emphasizing a scientific and empirical approach to understanding reality. Materialism often leads to a focus on tangible, observable phenomena while dismissing metaphysical or supernatural explanations.
