That does not in any way guarantee that any two people can or will agree on it or even sense it. The problem with people is that we are all biologically predisposed not to truth but to whatever is convenient, so truth is abstract. Its like a very tiny object or something on our back that we can't quite reach. Convenience often is mutual to the truth, but that doesn't make us truthful beings. Too much truth people do not like and can't see. Its a psychological thing that we believe in truth yet are often not able to accept some things that are real.
People agreeing is irreverent to the truth (insert flat earth example). Does not matter if i see or sense the truth, just because i think or believe something to be true does not mean it's true (again, insert flat earth example). My point at the end of the day is, that there is a truth to everything and only 1 truth each question. Just like saying Obama is the 44th president of the USA, that won't change with context. The USA has only had 45 presidents so far, Obama is and always be the 44th and Trump will always be the 45th one. That won't change over time.
