1 definition by practical proposition
Any claim that can be expressed as negative, thanks to the rule of double negation. This rule states that any proposition P is logically equivalent to not-not-P. Prove P is true and you can prove P is not false.
Example1:
1. If Unicorns had existed, then there is evidence in the fossil record.
2. There is no existence of Unicorns in the fossil record.
3. Therefore, Unicorns never existed.
Example 2:
Jason: 'Hey, did you that Danish and Deriana are dating?'
Ashley: 'how do you know?'
Jason 'Sam told me'
Ashley: 'I don't think so, those two are pranksters. They play mind games and talk shit all the time and no one has actually seen them together. They're cyber bullies that have nothing better to do with their life plus they're both committed to other people, they're just cyber friends'.
Jason: 'IDK
Ashley: 'C'mon, don't be a pussy like Sam and believe everything you hear or read, if you can't prove it, don't presume it'.

Why is it that people insist that you can't prove a negative? I believe it is the result of two things.
1. Disappointment that induction is not bullet proof, airtight and infallible.
2. A desperate desire to keep believing whatever one believes even if all the evidence is against it and not being able to prove that the P-Word is proven to be true.
