Fundamental problems with many-valued logic

 Posts: 12,170 Add as FriendChallenge to a DebateSend a Message 5/9/2015 6:33:06 PMPosted: 1 year agoThe problem with any formulation of logic other than two-valued logic is that it necessarily devolves to two-valued logic. First, such a formulation either is distinguishable (logically distinct) from two-valued logic, or it is not. If one wants to claim that neither of these choices capture the truth of the matter, then one is simply making another two-valued judgement i.e., that, in fact, it is neither distinct nor identical, but something else (whatever that means). Second, either many-valued logic is true or it is not. One cannot say that it is "somewhat" true without invoking yet another two-valued statement, namely that many-valued logic IS somewhat true as opposed to true/false. All statements of fact use 2VL whether they explicitly acknowledge it or not.There are those who believe that irresponsible breeding practices, and the stupidity which fosters them, cannot be stemmed without damage to our freedom. But freedom, and much else as well, cannot tolerate the geometric prolificacy of stupidity. - Chris Langan -

If they don't, then they're not actually claiming anything, and the person asserting it might as well not speak.There are those who believe that irresponsible breeding practices, and the stupidity which fosters them, cannot be stemmed without damage to our freedom.

All statements of fact use 2VL whether they explicitly acknowledge it or notIf something is either true or false, meaning that which is true cannot be false and that which is false cannot be true, then, truth is simply and exclusively universal.A truth that is absolutely true, meaning independent of one's perspective, is an unknowable truth, being all limited sentient beings by necessity define the truth using the mechanisms of perception.You may say one may blindly know the truth, in other words know the absolute truth without the capacity to know absolutely. In order for one to know the absolute truth, being a truth that is not hedged in, or defined by partiality, he, or she, must be impartial in his, or her, comprehension of it. Being impartial, one must ascertain it fairly and without prejudice, having no bias or preference towards it. In other words, one must know, indiscriminately, it is the absolute truth and knowing it is the absolute truth must be objective and impartial in his, or her, understanding.

Since our perspective is obviously part of reality, absolute truth is not "independent" of our perspective - it merely extends beyond it. Since absolute truth applies to every aspect of reality absolutely, it is implicit in every aspect of reality. To perceive one and the same reality, human beings need a kind of "absolute knowledge" wired into their minds.There are those who believe that irresponsible breeding practices, and the stupidity which fosters them, cannot be stemmed without damage to our freedom.

 Posts: 12,170 Add as FriendChallenge to a DebateSend a Message 5/15/2015 1:58:29 AMPosted: 1 year agoAnother way to explain it is this:All meaningful theories aim at truth, and truth just means "what reality is". So all meaningful theories assert that reality is a certain way. Therefore, all meaningful theories imply that reality assumes a consistent form stable enough to be described in a specific way. Thus, many-valued logic requires two-valued logic in order to be true.There are those who believe that irresponsible breeding practices, and the stupidity which fosters them, cannot be stemmed without damage to our freedom.

Its a part of logical thinking but there nothing 2 it.. Because it cannot be determined one way or another , its rather just a Open ended statement
