It's wrong if it contradicts the evidence of raw sense data or knowledge derived logically from the evidence of raw sense data.
You can choose to reject even that, but there is no reason to make such a choice, and it would be supremely impractical to do so.

The view that knowledge based on sense data isn't really knowledge was advanced by Kant, and certainly helped make room for the Nazis. Marx also exploited the anti-knowledge ethos of the time with his dialectical materialism. Finally, religion thrives when the ability to know is denigrated; that was Kant's stated goal [1]. Religion is fundamentally dishonest and leads to an infinite plethora of evils.

- __MatrixMan__ 7y agoSense data in itself can't be contradicted because it contains no propositions. As for knowledge logically derived from the sense data--it is exactly the choice: "which logic should I choose to interpret this sense data?" that is in question. If you choose a logic where all models are wrong and some are useful, then it won't contradict knowledge derived according to itself. If instead you choose some other way, you're again not going to run into any contradiction. The choice of an epistemic theory can only be about utility. Truth and falsity can only come later because they must be expressed in terms of the chosen theory.
