Absolute knowledge of truth is not part of the human condition. However, we have many things we can do to increase our confidence of a particular idea. A proof is a good first step. The more formal the proof, the better our confidence. (My proof here is not particularly formal.) Also good is publishing a proof so that it's in front of many eyes; the more people that see it, the more chances there are that flaws will be spotted. A single flaw is enough to invalidate a proof.

Other good things to do: publication in a peer-reviewed journal. Also, use of a proof assistant, such as Coq, is an excellent, formal way of reinforcing proofs. But then we can ask, how do we verify the proof assistant is sound? This leads to infinite regress, which is part of why absolute knowledge of truth is impossible.

In practical terms, if, say, VC, Jan Hidders, and Vadim Tropashko don't find anything wrong with it, it's probably right. :-)
