In praxeology, methodological dualism is an epistemological position which states that it is necessary ─ based on our current state of knowledge and understanding ─ to use a different method in analysing the actions of human beings than the methods of the natural sciences (such as physics, chemistry, physiology, etc.).[1]
This position is based on the presupposition that humans differ radically from other objects in the external world. Namely, humans purposefully aim at chosen ends and employ chosen means to attain them (i.e. humans act), whereas other objects in nature ─ such as, for example, sticks, stones, and atoms ─ do not.[2]
Methodological dualism is not a metaphysical or ontological doctrine, and refrains from making such judgments.[3]
