epistemiology

The word epistemology comes from the Greek word episteme that means knowledge and logos that means study or theory, therefore epistemology is the theory of knowledge. It analyzes philosophical foundations, structures, and how knowledge is created, the way that investigates, explains, and interprets their results.

Materialism is the current claim that everything is matter and that the only reality that exists is material the reality

 Rationalism is the current that states that reality can be known without any prior experience

 Empiricism asserts that experience is necessary to know something.

Realism exposes that ideas exist whether or not they are thought.

 Idealism assumes that objects cannot exist without a mind that is aware of them

Positivism asserts that all knowledge must be based on sensory experience.

Logical positivism emerged in the late 1920s in what is known as the Vienna Circle. Its thought is born of empiricism and is known as total empiricism based on logic to avoid ambiguity.

Phenomenology is a doctrine developed by Edmund Husserl. It proposes that consciousness involves a relationship with the object and keeps the essence of the phenomenon.

Analytic philosophy of language of Wittgenstein says that everything that can be thought can be expressed by language
