1.Scientism
The term scientism can be used as a neutral term to describe the view that natural science has authority over all other interpretations of life, such as philosophical, religious, mythical, spiritual, or humanistic explanations, and over other fields of inquiry, such as the social sciences.

2.Empiricism
In philosophy generally, empiricism is a theory of knowledge emphasizing the role of experience, especially sensory perception, in the formation of ideas, while discounting the notion of innate ideas.
The term "empiricism" has a dual etymology. It comes from the Greek word εμπειρισμός, the Latin translation of which is experientia, from which we derive the word experience. It also derives from a more specific classical Greek and Roman usage of empiric, referring to a physician whose skill derives from practical experience as opposed to instruction in theory.

3.Logical Positivism
Logical positivism (later and more accurately called logical empiricism) is a school of philosophy that combines empiricism, the idea that observational evidence is indispensable for knowledge of the world, with a version of rationalism, the idea that our knowledge includes a component that is not derived from observation.
