Here is another point of view.

What is the function of a symbol as subject? To stand for certain things. Then if the predicate be true of all the things that it stands for as [yet ??] that is for all which we [yet ??] know it to stand for, the symbol may stand as subject provisionally.

The difficulty with this is that it does not represent the synthetic probability of the inference.

It is however a good idea [hest ??] a random selection is equivalent [to ??] all known -- the genus of those two would [like that ??].

The difficulty with this is that it does not [Dr?] the synthetic probability of the inference.

It is however a good idea that a random selection is equivalent to all known _ the genius of there trio would hit that.

We have

M is P in the sense that the actual denotation of things taken under M are P ([contingent ??]) [and ??] 2nd in the sense that all possible things taken under M would be P. (necessary)

On the same principle

S is M in the senses 1st that S has the qualities taken of M (attributive) 2nd that S has all qualities of M (subsumptive)

Still it may be doubted [if ??] hypothesis proceeds by random selection of qualities of the new predicate.

Then the principle would be the possible is like much of the actual.

1869 April 1.

What is taken -- the [present ??] -- of a class if it has any common character -- that character probably belongs to the class, or to the majority of it. or something like it And if what is known of the characters of a thing belong to another thing, the second thing has most of the characters of the first, probably.

The reason is that the parts compose the whole and therefore what does not belong to a number of parts the majority of the whole does not belong to the majority of the parts.

What does not belong to the most of the parts does not belong to the parts taken [mostly ??], because the parts to be taken are all the possible parts.

The distinction must be observed between Induction & Hypothesis as formal operations & between them as leading to truth.

Certain characters are those know to belong to M
