the view that everything that exists is physical is known as
Reality The view that there is a reality independent of any beliefs, perceptions, etc., is called realism. More specifically, philosophers are given to speaking about "realism about" this and that, such as realism about universals or realism about the external world. Generally, where one can identify any class of object, the existence or essential characteristics of which is said not to depend on perceptions, beliefs, language, or any other human artifact, one can speak of "realism about" that object.
Ceteris paribus There is ongoing debate in the philosophy of science concerning ceteris paribus statements. On the logical empiricist view, fundamental physics tends to state universal laws, whereas other sciences, such as biology, psychology, and economics, tend to state laws that hold true in normal conditions but have exceptions, ceteris paribus laws (cp laws).[2] The focus on universal laws is a criterion distinguishing fundamental physics as fundamental science, whereas cp laws are predominant in most other sciences as special sciences, whose laws hold in special cases.[2] This distinction assumes a logical empiricist view of science. It does not readily apply in a mechanistic understanding of scientific discovery. There is reasonable disagreement as to whether mechanisms or laws are the appropriate model, though mechanisms are the favored method.[3]
