We have one claiming to be a teacher of logic on this list who states that logic is a branch of mathematics. Is his claim founded in truth or the mere regurgitation of a false notion possibly stated by his mentors?

Google some words and learn some things. Formal logic Informal logic Mathematical logic And then for fun google "trivium" &/or (logical &/or) "quadrivium" Of course the other term you might want to define is 'teach' . . . teach what? And don't forget "boolean algebra" and "set theory" and "programmatic logic" and I ain't teeched much of nuthin' in a week or two.

Then also there is www.christianlogic.com where one can learn to think critically and also how to teach children to process information correctly and make informed decisions in a biblical manner! Its a great site!

wow... people actually studying logic... what an insightful concept... we need more people like that. God bless!

The scope of logic just keeps expanding. Let’s see if I understand this so far. Logic is a branch of mathematics, therefore, Christian logic must be a branch of Christian mathematics. Formal logic is a branch of formal mathematics. Informal logic is a branch of informal mathematics. Mathematical logic is just a branch of itself. Don’t even think about questioning this logic, for logic, according to the teacher on this list, “really isn’t debatable, it just is.” It feels soooooo good to be right. :smilewinkgrin:

It would have helped you if you had read up on the scope of the different areas of 'logic'. Google would do you a good start. While formal logic can be represented mathematically, mathematical logic is usually described using boolean logic (algebra) or set theory. Informal logic does not break down as easily as formal logic. It is not 'more difficult' to describe, however it is not as 'constrained' as formal logic. Have fun.

2BHizown about logic: // ... to process information correctly and make informed decisions in a biblical manner ... // The dogmatic person MUST not allow that to happen. Dogmatic -- 2. asserting opinions in an arrogant manner BTW, My 3rd grader ward had a lesson about bats (the animal) where she correctly identified statements of opinions and facts. The idea of Mathematics is to quantize the nature of the Universe (God's Creation). The idea of Logic (from the Mathematics viewpoint) is to comprehend the truth (God's Creation) of the nature of the Universe (God's Creation).

HP: The question set forth in the OP concerned whether or not our 'resident teacher of logic' comment that ‘logic is a branch of mathematics,’ is correct or not. The question did not concern whether or not there was a division or branch of logic that involves mathematics. You obviously have done your homework. Was he correct in his statement or not? Is logic a branch of mathematics? If so, why?

Here is you a sermon from Sets (another branch of Mathmetics) An infinite set may be divided into any finite number of infinite sub-sets. For example: eternity is an infinite number of time units (days, hours, minutes, millinnial, etc.). Though there is a large quanity of saints before the throne of God (Rev 7:14), it is a finite number. So let me see, each person's time with Jesus (say one minute every billion years) would be an infinite sub-set of of Eternity. My time in heaven spent with Brother Heavenly Pilgrim (HP) /say one hour each Trillion years, will also be in infinite sub-set of eternity. So I better learn to get along with brother Heavenly Pilgrim, for I will spend an eternity ALONE with him. Interesting, Mathematics & Sermons :saint:

How do you define 'logic'? How do you define 'mathematics'? All mathematics (and for that matter: politics, religion, economy, etc) can be developed by using logic. So it only seems proper that, though originally logic was developed outside mathematics, that mathematics took logic as a way to explain mathematics. One part of logic is for people to agree upon basic definitions and basic statements. But the start of basic definitions depends upon certain 'undefined terms' (that doesn't mean we don't have the foggiest what those terms mean, but that the undefined term represents the basic statements. Examples: If your undefined terms are point, line, and plane; then your logic will develop a geometry. If your undefined terms are man, God, faith; then your logic will develop a religion. CAVEAT: Christianity is NOT a religion (man trying to figure out and reach out to God). Christianity is God reaching out to man. If your undefined terms are man, the state, and thier relationships; then your logic will develop a politics. More next post about the meaning and purpose of the 'basic statements' and a short history thereof.

HP: From this information I believe I can logically assume then that logic is NOT a branch of mathematics, for you say that ‘mathematics took logic as a way to explain mathematics.’ It would appear to me that if we were trying to explain the connection that exists between the two, we would be more correct to say that mathematics is a branch of logic, than the other way around. I personally do not see either as a branch of the other. One simply utilizes the other. Logic, in its most basic form, is a God given intuitive ability utilized to help discern the truth. Logic has existed in the mind of God eternally, and has been part of our makeup as long as man has been cognizant. One needs no formal training in the least to utilize it properly. It is simply reasoning in a fashion that is in accordance to truth, is it not? We utilize logic in all cognizant endeavors, mathematics only being one.
