Non-monotonic core: Reflexivity, Cut, Cautious Monotonicity, Left Logical Equivalence, Right Weakening [Antonelli]
|
|
Full Idea:
Conservative core of non-monotonic logic:Reflexivity (p proves p), Cut (if p proves q, it proves their joint implications), Cautious Monotonicity, Left Logical Equivalence (equivalences have same consequences), Right Weakening (non-m preserves classical).

From:
G. Aldo Antonelli (Non-Monotonic Logic [2014], 3.5.1)

A reaction:
[Highly compressed, and without symbols]

People don't actually use classical logic, but may actually use non-monotonic logic [Antonelli]
|
|
Full Idea:
Test subjects seem to perform very poorly in various reasoning tests (Wason Selection, Suppression Task), suggesting logic has a subordinate role, but this may be using classical logic, where non-monotonic logics would be more appropriate.
|
|
From:
G. Aldo Antonelli (Non-Monotonic Logic [2014], 4)
|
|
A reaction:
Fred Sommers presents his Term Logic (based on Aristotle) as closer to how people actually reason. It is certainly crazy to infer that most people's everyday reasoning is irrational. Induction is highly rational; it's just not deductive.

When we need to do something, we depute an inner servant to remind us of it [Proust]
|
|
Full Idea:
Whenever we have something definite to do at a given moment, we depute a certain person inside us who is accustomed to that sort of duty to keep an eye on the clock and warn us of the time. This inner servant reminded me that Albertine was coming soon.
|
|
From:
Marcel Proust (Remembrance of Things Past [1922], Cities.2.1)
|
|
A reaction:
I think Proust is wrong that we 'depute' this servant. I think it comes as a built-in feature, and the servant could never be abandoned or sacked, no matter how poor the service. Each of us is a team, which includes servants.

Because human life is what is sacred, Mosaic law has no death penalty for property violations [Johnson,P]
|
|
Full Idea:
Where other codes provided the death penalty for offences against property, in Mosaic law no property offence is capital; human life is too sacred, where the rights of property alone are violated.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt I)
|
|
A reaction:
We still preserve this idea in our law, and also in our culture, where we are keen to insist that catastrophes like earthquakes or major fires are measured almost entirely by the loss of life, not the loss of property. I approve.

The Pharisees undermined slavery, by giving slaves responsibility and status in law courts [Johnson,P]
|
|
Full Idea:
It is no accident that slavery among Jews disappeared with the rise of the Pharisees, as they insisted that all were equal before God in a court. Masters were no longer responsible for actions of slaves, so a slave had status, and slavery could not work.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt II)
|
|
A reaction:
As in seventeenth century England, the rise of social freedom comes from religious sources, not social sources. A slave has status in the transcendent world of souls, despite being a nobody in the physical world.

Mosaic law was the first to embody the rule of law, and equality before the law [Johnson,P]
|
|
Full Idea:
Mosaic law meant that God ruled through his laws, and since all were equally subject to the law, the system was the first to embody the double merits of the rule of law and equality before the law.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt I)
|
|
A reaction:
If this is correct, it seems to be a hugely important step, combined with Idea 1659, that revenge should be the action of a the state, not of the individual. They are the few simple and essential keys to civilization.

Man's life is sacred, because it is made in God's image [Johnson,P]
|
|
Full Idea:
In Mosaic theology, man is made in God's image, and so his life is not just valuable, it is sacred.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt I)
|
|
A reaction:
The obvious question is what exactly is meant by "in God's image". Physically, spiritually, intellectually, morally? I am guessing that the original idea was intellectual, because we are the only rational animal. The others seem unlikely, or arrogant.

A key moment is the idea of a single moral God, who imposes his morality on humanity [Johnson,P]
|
|
Full Idea:
The discovery of monotheism, and not just of monotheism but of a sole, omnipotent God actuated by ethical principles and seeking methodically to impose them on human beings, is one of the greatest turning-points in history, perhaps the greatest of all.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt I)
|
|
A reaction:
'Discovery' begs some questions, but when put like this you realise what a remarkable event it was. It is a good candidate for the most influential idea ever, even if large chunks of humanity, especially in the orient, never took to monotheism.

Sampson illustrates the idea that religious heroes often begin as outlaws and semi-criminals [Johnson,P]
|
|
Full Idea:
Sampson is the outstanding example of the point which the Book of Judges makes again and again, that the Lord and society are often served by semi-criminal types, outlaws and misfits, who become folk-heroes and then religious heroes.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt I)
|
|
A reaction:
This illustrates nicely Nietzsche's claim, that the jews were responsible for his 'inversion of values', in which aristocratic virtues are downgraded, and the virtues of a good slave are elevated (though Sampson may not show that point so well!).

The Torah pre-existed creation, and was its blueprint [Johnson,P]
|
|
Full Idea:
The Torah was not just a book about God. It pre-existed creation, in the same way as God did. In fact, it was the blueprint of creation.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt III)
|
|
A reaction:
You can only become a 'people of the book' (which Moslems resented in Judaism, and then emulated) if you give this stupendously high status to your book. Hence Christian fundamentalism makes sense, with its emphasis on the divinity of the Bible.

Judaism involves circumcision, Sabbath, Passover, Pentecost, Tabernacles, New Year, and Atonement [Johnson,P]
|
|
Full Idea:
The practices of Judaism developed during their Exile: circumcision, the Sabbath, the Passover (founding of the nation), Pentecost (giving of the laws), the Tabernacles, the New Year, and the Day of Atonement.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt II)
|
|
A reaction:
These were the elements of ritual created to replace the existence of a physically located state. An astonishing achievement, not even remotely achieved by any other state that was driven off its lands. A culture is an idea, not a country.

Zoroastrians believed in one eternal beneficent being, Creator through the holy spirit [Johnson,P]
|
|
Full Idea:
Cyrus the Great was a Zoroastrian, believing in one, eternal, beneficent being, 'Creator of all things through the holy spirit'.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt II)
|
|
A reaction:
Is this the actual origin of monotheism, or did they absorb this idea from the Jews? The interesting bit is the fact that the supreme being (called Marduk) is 'beneficent', which one doesn't associate with these remote and supposed pagans.

Immortality based on judgement of merit was developed by the Egyptians (not the Jews) [Johnson,P]
|
|
Full Idea:
The idea of judgement at death and immortality on the basis of merit were developed in Egypt before 1000 BCE. It is not Jewish because it was not in the Torah, and the Sadducees, who stuck to their texts, seemed to have denied the afterlife completely.
|
|
From:
Paul Johnson (The History of the Jews [1987], Pt II)
|
|
A reaction:
This is the idea considered crucial to religion by Immanuel Kant (Idea 1455), who should be declared an honorary Egyptian. To me the idea that only the good go to heaven sounds like sadly wishful thinking - a fictional consolation for an unhappy life.
