The principles of logical proof


LANGER, SUSANNE K (1953)(1967) An Introduction to Symbolic Logic, Dover Publications, New York. (Philosophy).

The review continues... Me learning symbolic logic continues:

Key symbols

≡df = Equivalence by definition : = Equal (s) ε = Epsilon and means is ⊃ = Is the same as ⊨ is Entails ˜ = Not ∃ = There exists ∃! = There exists ∴ = Therefore . = Therefore  <  = Is included v = a logical inclusive disjunction (disjunction is the relationship between two distinct alternatives). x = variable . = Conjunction meaning And 0 = Null class cls = Class int = Interpretation

Langer explains that the propositions using tautology will use no exponents. (215). In other words, in multiplication, there will not be a smaller exponent number present, to the right of the base number. (215). This is in the context of multiplication.

Therefore, z x z = z, and z2, z3 and related, etcetera in not used. (My example, based on Langer (1953)(1967: 215). In a similar way with addition 2z cannot be arrived at with z + z = z. With addition, 23, 34 etcetera is not arrived at. (My example, based on Langer (1953)(1967: 215).

'A calculus is any system wherein we may calculate from some given properties of our elements to others not explicitly stated.' (235).

Calculus is expressed in symbols in general terms and their relations in general it is in algebra. (236). The classes provided through general propositions is genuine algebra. (236).

The principles of logical proof...

Importantly, philosopher Langer explains that there is no guarantee that there is truth in a logical system. (189). Logic does not necessarily promote a fact, rather 'it stands for the conceptual possibility of a system'. (189). Logic documents with the deduction of premises. It stands for 'the consistency of all propositions'. (189). It is standing for logical validity. (189), not factual certainty or truth. (189). This is standard from philosophy, logic, texts. Certainly not something Langer or I manufactured as original.

In many cases when a person states that a premise or argument is logical, the person means that it is true. But a premise or argument can be logical and false. Therefore, it would be more accurate in many cases to claim that a premise or argument is true and or reasonable.

On standard views, logic has as one of its goals to characterize (and give us practical means to tell apart) a peculiar set of truths, the logical truths...

Langer demonstrates the following as logical:

Napoleon discovered America
Napoleon died before 1500 A.D. (189).
Conclusion

America was discovered before 1500 A.D. (189).

These two premises imply that America was discovered before 1500 and Langer opines that a third proposition that would be derived (a conclusion, my add) would also be logical and valid. (189). 

Indeed the first two premises are historically false. (189). They are still logically consistent, while the consequent is true that America was discovered before 1500 A.D. (189).

Also logical, but a true premise:

n= Napoleon
d= Discover
a= America

n ˜ (d+a)

Napoleon did not discover America.

Apollinarianism


Apollinarianism was discussed in the video lecture below:

Grenz, Guretzki and Nordling explain that this view was the teaching of fourth century bishop of Laodicia, Apollinarius, that reasoned in the incarnation of Christ, God the Son, took on a human body but not a human mind or human spirit. (13).

The divine logos took the place of the human mind or spirit (
nous νος(13).

In other words, the incarnate God-man, had a divine mind and spirit alone. (13).

Erickson explains that 
 apollinarianism was an overreaction to Arianism. (714).

Apollinarius taught the dualism of the incarnate Jesus Christ having two complete natures, absurd. (714). Instead Jesus Christ was part human, but mostly divine. (714).

Therefore, the incarnate God-man was different than every other human being. (715). Christ did  not have a human mind or spirit (
nous νος(715). In this view, the centre of Christ's consciousnesses is the divine. (715). This serves as explanation of how Jesus Christ would remain sinless. (715). 

Erickson correctly points out that with this view, the divine nature of Jesus Christ would swallow up the human nature. (715). It also would have Christ lacking human will, human reason, and human mind and this doctrine was condemned at the Council of Constantinople in 381. (716).

Being incarnate implies, fully divine, as in fully God, and fully human, I am in agreement with Erickson and Bruce Gore from the video that in one person, Jesus Christ possessed and still possesses one human nature, spirit/mind and one divine nature, spirit/mind.

The spirit/mind of God, although triune, is infinite and eternal. Jesus Christ's human spirit/mind is finite and everlasting, but not eternal as it was created in the incarnation. This explains, in part, why as God the Son, Jesus Christ in his humanity depended on God and God the Father for guidance. Jesus Christ was still fully God, but humbled himself as fully human.

Philippians 2: 8 New American Standard Bible

Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross.

There is a theological debate whether or not Jesus Christ had his sinful human nature purged from his humanity with the incarnation; or that Jesus Christ had the sinful human nature from the fall, and never accessed it.

Thiessen quotes Strong who states that the incarnation purged depravity from Christ. p.305. This view would be contrasted by scholars such as Mounce and Cranfield:

Cranfield in his Romans commentary p.176, comments on the likeness of sinful flesh. Cranfield states with what he thinks is the best explanation, that being that the Greek word for likeness is not to water down Christ's fallen human nature, as in being fully human, but is to draw attention that the fallen nature was assumed but Christ did not become a fallen human being.

So, unlike some views that reason Christ's sinful human nature was purged out at the incarnation, this view reasons it was there but because of his perfect obedience and I would reason deity, he did not become a fallen human being that sinned. So, in a sense in the likeness of sinful flesh, he had fallen human nature. In another sense in the likeness of sinful flesh, he did not have an active fallen human nature that would have led to sinful thoughts and choices.

Mounce in his Romans commentary sees it the same way on p.175-176, Christ took upon a fallen nature but did not become completely like us, as in sinners.

The Orthodox Study Bible: John 3: 19-20


The Orthodox Study Bible, New Testament and Psalms, (1993) Saint Athanasius Orthodox Academy,Thomas Nelson Publishers, Nashville, Tennessee.
---

I was discussing Christian evangelism and witnessing and obstacles to them, the other day, while my good friend drove us around.  While pulling into a Chevron station my good friend wisely quoted John 3: 19-20...

From the New American Standard Bible:

19 This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. 20 For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed.

The Orthodox text explains in regard to 19-21:

'A profound insight. Goodness and a pure heart welcome the light; whereas evil deeds and malice resist the light and seek to hide in the darkness.' (219).

From Strong's:

4655 for darkness in John 3: 19. (88).

σκότος

Page 88







Bauer explains that here is this context, darkness can be understood as 'religious and moral darkness, of darkening by sin, of the state of unbelievers and of the godless.' (757-758).

I appreciate the definitions from Orthodoxy and the Greek New Testament scholarship from Strong and Bauer. From my Reformed perspective, the corrupted, fallen nature of humanity (Genesis 3, Romans) prohibits a person in darkness from embracing the light to the point of salvation.

New American Standard Bible

Romans 5:10 10

For if while we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved [a]by His life. Footnotes: [a] Romans 5:10

Colossians 1: 21-24

21 And although you were formerly alienated and hostile in mind, engaged in evil deeds, 22 yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach— 23 if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel that you have heard, which was proclaimed in all creation under heaven, and of which I, Paul, was made a minister.

Human beings as enemies of God and being alienated from God with a hostile mind (s), in my opinion cancels out theology/philosophy of person's simply responding to the offer of salvation using libertarian free will (incompatibilism).

In contrast, God, through the Holy Spirit, regenerates the persons (Titus 3, or same makes born again John 3) applying the atonement and resurrection work of Jesus Christ to those persons that simultaneously embrace, as secondary cause, with limited free will, what God has caused, choosing them (Ephesians 1-2) (compatibilism).

This is neither libertarian free will, nor divine force of coercion.

From my Reformed perspective, the goodness and pure heart (I would state purified heart) that welcomes the light is the heart regenerated by the Holy Spirit.

Sentimental theology/philosophy


April 19, 2019 

Happy Good Friday

It seems to me, many secular worldviews ignore the Scriptural revelation, as in the bible in context and related theology, and assume Scriptural revelation is irrelevant in the establishment of true, primarily important premises.

Admittedly, some religious worldviews, accept the bible, but with differing non-orthodox, non-traditional, interpretations.

However, biblical studies, theology (religious philosophy within the bible), philosophy of religion (religious philosophy outside the bible) are legitimate academic disciplines as are, for example, science, mathematics and psychology.

(I am not stating the Christian message needs to be complex, but it should be considered even in its most simple context, for example, at children’s Sunday school)

This ignorance of religious studies significantly negates the establishment of a true worldview.

Sentimental theology/philosophy 

Scientifically and empirically (by use of the senses) it appears that human beings die and all that is left are physical remains. Some religions and religious persons believe in an existence of the human spirit that exists after death. In the media, and at funerals it is said sometimes that the person that has passed away has gone to a better place. This is speculative, assumed and hoped for, since the departed was usually and seemingly a good person, humanly speaking.

(I am not trying to be uncaring or mean here. I am attempting to be reasonable and rational.)

This appears to be sentimental theology, and by that I mean theology that is primarily driven by feelings, that is speculative and lacks a significant use of reason that can be supported by historically based religious revelation. Please note, I am not stating that all theological speculation is lacking the significant use of reason.

The naturalist can dismiss this sentimental theology on empirical grounds. If the Scripture is not considered, this type of approach may be more accurately described as sentimental philosophy.

Simon Blackburn defines naturalism as generally a view that nothing resists explanation from methods of natural sciences. A naturalist will therefore be opposed to the concept of mind-body since it allows for the possible explanation of human mental capacity outside of science. Blackburn (1996: 255).

Henry Clarence Thiessen explains that naturalists reject the idea of God and view nature as self-sufficient and self-explanatory. Thiessen (1956: 32). A Christian theist such as myself can reason that the person that has died was morally imperfect as we all are, was part of, and affected by, the problem of evil, did not receive direct communication from God normally, and likely not at any point, prior to death. From this there is not an obvious reason to realistically, and reasonably assume that a person that has passed away goes to a better place within a speculative theistic model which lacks historically based religious revelation.

Within a speculative theistic model, I would reason that if a person lives an earthly temporal life apart from direct communication with God, then it is reasonable to assume that if God does grant everlasting life, it will not be some type of heaven in God’s presence, and therefore not necessarily a better place. Biblical Christianity is not dependent on sentimental theology. Millard Erickson writes that natural theology deduces that God can be understood objectively through nature, history, and human personality. Erickson (1994: 156).

But, it should be stated that although natural theology can perhaps bring a person to a limited knowledge of God, it does not provide revealed information concerning salvation or everlasting life for human beings. In a similar way, the study of philosophy of religion may produce true premises in regard to God and religion, but as it is outside of Scripture, it does not provide scriptural revelation that explains salvation. Erickson explains that Biblical revelation views God as taking the initiative to make himself known to followers. Erickson (1994: 198).

This would be a more effective way than natural revelation as God reveals personal things about himself through his prophets, apostles, scribes, and of course Jesus Christ, who is both God and man. It can be reasoned that this revelation is documented in the Bible with persons that are historical and not mythological.

Thiessen writes that God revealed himself in the history of ancient Israel. Thiessen (1956: 33). God is presented as personally appearing to chosen persons in the Hebrew Bible through dreams, visions and directly. Thiessen (1956: 34). Thiessen explains that miracles were also noted to occur within the Hebrew Bible, miracles being unusual events that were not a product of natural laws. Thiessen (1956: 35). The Hebrew Bible and New Testament present historical persons that experienced the supernatural God and supernatural occurrences.

Some will accept the historicity of these persons, but deny the supernatural aspects of the Bible, but according to the New American Standard Bible presented by Charles Caldwell Ryrie and the Lockman Foundation, approximately 40 authors wrote the Biblical texts over a period of approximately 1600 years. Ryrie (1984: xv).

Not all these persons knew each other and yet spoke of the same God that revealed himself progressively over time. The atoning work and resurrection of Christ was documented and discussed by several historical authors within the New Testament and through this work everlasting life is provided to followers of Christ. The book of Revelation describes the culminated Kingdom of God in Chapters 21-22.

The New Testament provides information about the historical Jesus Christ and his followers in historical setting and this gives much more credibility for theology concerning the concept of life after death in the presence of God, than does sentimental theology which denies or twists the concepts of Scripture in order to fit some type of speculative theistic hope for everlasting life which is devoid of the significant use of reason and revelation.

Without revelation that is legitimate, religious history, there is not convincing evidence for believing that God will provide a departed person with meaningful everlasting life, outside of revelation from God explaining by what means he would bring a person that has passed away into his presence forever, and/or place them in a better place.
