There are classes of these abstractive elements which are of great importance.
2
Such a segment can also be defined as an abstractive element.
3
This definition defines the location of an element in any type of abstractive element.
4
There are also the correlative abstractive sets which I call the sets of σ-antiprimes.
5
In my last lecture I have already investigated one class of abstractive elements, namely moments.
6
Thus all abstractive sets belonging to the same element are equal and converge to the same intrinsic character.
7
Furthermore it was also noted that there were many spatial abstractive elements which we had not yet defined.
8
An 'abstractive element' is the whole group of abstractive sets which are equal to any one of themselves.
9
It is evident that-withthis meaning of σ-every abstractive set equal to a σ-prime is itself a σ-prime.
10
In particular we can conceive an abstractive set of which all the members have point-contact at the same event-particle.
11
This emergence of a definite intrinsic character from an abstractive set is the precise meaning of the law of convergence.
12
According to my own theory it only differentiates itself from time at a somewhat developed stage of the abstractive process.
13
We have got to annex some condition to the root property of being covered by any abstractive set which it covers.
14
The importance of the equality of abstractive sets arises from the assumption that the intrinsic characters of the two sets are identical.
15
We will first consider the definition of some of these abstractive elements, namely the definitions of solids, of areas, and of routes.
16
In so doing we are also cutting out those abstractive elements which cover sets of event-particles, without these elements being event-particles themselves.
