Merging

I don't see the necessity of this page being merged with cardinality.

I would definetely not merge the two, they should be kept separate.

Julius Baumann?

Sparing the gory details, I find Frege's work (Sense and Reference) to be philosophically naive. I often wondered how Frege could possibly espouse a theory of meaning so obviously at odds with Kant without some defense of his theory vis a vis Kant.

So the comment that Frege had "probably never read Hume" leads me to wonder if Frege ever read Kant. If Frege never read either Hume or Kant, isn't analytical philosophy, of which Frege is one of the "fathers", in some sense an illegitimate child? Can whoever wrote this page include some more details regarding Frege's philosophical background?

Thanks in advance,

That information is likely to be found on the page for Gottlob Frege. I would also recommend J. Alberto Coffa's book "The Semantic Tradition from Kant to Carnap to the Vienna Station".--138.251.242.34 (talk) 12:01, 9 January 2010 (UTC)[reply]

Fs and Gs??

Why would a supposedly important principle be stated using nonsense words Fs and Gs. And why would anybody care about them? Visibly Hume never mentioned them. So maybe the intro to this article should be restated in a meaningful way. Marc van Leeuwen (talk) 12:42, 7 March 2010 (UTC)[reply]

It is stated in this way by Frege and HP figured prominently in the literature on Frege (rather than the literature on Hume). Mars2mogwai (talk) 20:51, 25 July 2011 (UTC)[reply]

In any case I think it should be explained (parenthetically) what exactly "Fs" and "Gs" mean (I think they just stand for arbitrary things, in which case why not use the more familiar "Xs" and "Ys"?) Joel Brennan (talk) 16:12, 9 May 2020 (UTC)[reply]

What about using in the lead the contemporary mathematical definition of set cardinality; Frege's original phrasing (if available) could be given as a footnote, or in the "Origins" section. Concretely, I suggest the sentence "... HP says that two sets F and G have the same number of elements if and only if there is a one-to-one correspondence (a bijection) between F and G". Note that bijection needn't be linked again. - Jochen Burghardt (talk) 14:14, 10 May 2020 (UTC)[reply]
