If you know your father, but don't recognise your father veiled, you know and don't know the same person [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'undetected' or 'veiled' paradox of Eubulides says: if you know your father, and don't know the veiled person before you, but that person is your father, you both know and don't know the same person.

report of Eubulides (fragments/reports [c.390 BCE]) by R.M. Dancy - Megarian School

A reaction:
Essentially an uninteresting equivocation on two senses of "know", but this paradox comes into its own when we try to give an account of how linguistic reference works. Frege's distinction of sense and reference tried to sort it out (Idea 4976).

Removing one grain doesn't destroy a heap, so a heap can't be destroyed [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'sorites' paradox of Eubulides says: if you take one grain of sand from a heap (soros), what is left is still a heap; so no matter how many grains of sand you take one by one, the result is always a heap.

|
A reaction:
(also Cic. Acad. 2.49) This is a very nice paradox, which goes to the heart of our bewilderment when we try to fully understand reality. It homes in on problems of identity, as best exemplified in the Ship of Theseus (Ideas 1212 + 1213).

I don't admit infinite numbers, and consider infinitesimals to be useful fictions [Leibniz]
|
|
Full Idea:
Notwithstanding my infinitesimal calculus, I do not admit any real infinite numbers, even though I confess that the multitude of things surpasses any finite number, or rather any number. ..I consider infinitesimal quantities to be useful fictions.
|
|
From:
Gottfried Leibniz (Letters to Samuel Masson [1716], 1716)
|
|
A reaction:
With the phrase 'useful fictions' we seem to have jumped straight into Harty Field. I'm with Leibniz on this one. The history of mathematics is a series of ingenious inventions, whenever they seem to make further exciting proofs possible.

It would be absurd if even a free constitution did not impose restraints, for the public good [Hume]
|
|
Full Idea:
A republican and free form of government would be an obvious absurdity, if the particular checks and controls, provided by the constitution, had really no influence, and made it not the interest, even of bad men, to act for the public good.
|
|
From:
David Hume (That Politics may be reduced to a Science [1750], p.14)
|
|
A reaction:
Presumably if you attain absolute power you can write any old constitution you like (Clause 1: the presidency is for life). But there does seem much point in doing it - unless it is to facilitate the use of the law for persecutions.

Nobility either share in the power of the whole, or they compose the power of the whole [Hume]
|
|
Full Idea:
A nobility may possess power in two different ways. Either every nobleman shares the power as part of the whole body, or the whole body enjoys the power as composed of parts, which each have a distinct power and authority.
|
|
From:
David Hume (That Politics may be reduced to a Science [1750], p.15)
|
|
A reaction:
He says the first type is found in Venice, and is preferable to the second type, which is found in Poland. Presumably in the shared version there is some restraint on depraved nobles. The danger is each noble being an autocrat.
