Please provide formal proof (or near enough, according to ability) for your decision as to which of the following two assertions is correct:
"Even if a claim is arrived at fraudulently, that does not mean the claim is untrue."
"A claim that is true, cannot be arrived at fraudulently."
A simple example of where the choice between these two assertions may come into play:
Someone publishes a claim that the Earth is flat. The claim is arrived at fraudulently, with empirical falsehoods and illogical reasoning. If we believe in the first assertion, we may consider the Earth to be flat, regardless. If we believe in the second assertion, the Earth cannot be flat.
EDIT:
To clarify, the idea of a "claim arrived at fraudulently" is that the claim is arrived at by empirical falsehoods, illogical reasoning is not enough, as any truth may be placed in an illogical sentence.
