Hard Problem of Fact
The dilemma that facts are not raw, uninterpreted bits of the world, but are always "theory-laden." What counts as a fact depends on the conceptual framework you're using. A fact is a statement about the world that we agree is incontrovertible within a given paradigm. The hard problem is that when paradigms shift (e.g., from Newtonian to Einsteinian physics), old facts can become false or meaningless. This means facts are not eternal building blocks of knowledge, but temporary settlements in an ongoing negotiation between observation and interpretation.
Example: For centuries, "The Sun revolves around the Earth" was a brute fact, confirmed by daily observation. The shift to heliocentrism didn't change the raw data (the sun's motion in the sky), it changed the interpretive framework. The "fact" became "The Earth rotates, creating the illusion of solar motion." The hard problem: There is no neutral observation language. What you call a fact reveals your theoretical commitments. A fact is like a piece in a puzzle—it only has a definite shape and place relative to the picture you're trying to build. Hard Problem of Fact.
