Obviously this distinction is critical. No way are "presupposition" and "prejudice" synonyms.... Thank you, Alamo-Girl, for making the distinctions between them explicit.
Certainly world views or cosmologies are at the very foundation of our thought. The point is to become aware of them and how they affect one's methods, reasoning, and conclusions. This requires a rigorous self-analysis -- which is NOT the same thing as "introspection."
Socrates urged, "Know thyself." In effect, this is to become capable of objectively recognizing the habits, forms, and tendencies of one's own thought processes. Anyhoot, if one can't get control over one's presuppositions, one is skewing one's analytical findings right from the get-go. JMHO FWIW
Thank you so much, Alamo-Girl, for your excellent post/essay!
