Highest reason is aesthetic, and truth and good are subordinate to beauty [Hegel]
|
|
Full Idea:
I am now convinced that the highest act of reason, which embraces all ideas, is an aesthetic act, and that truth and goodness are brothers only in beauty.
|

From:
Georg W.F.Hegel (Oldest System Prog. of German Idealism [1796]), quoted by Simon Critchley - Continental Philosophy - V. Short Intro Append
|
|
A reaction:
This seems to be the distinctive value framework of the romantic movement and the nineteenth century, where art is destined to replace religion. However, Plato in the Symposium is an interesting ally. Aim for beauty, and the rest follows?

Obtaining numbers by abstraction is impossible - there are too many; only a rule could give them, in order [Benacerraf]
|
|
Full Idea:
Not all numbers could possibly have been learned ŕ la Frege-Russell, because we could not have performed that many distinct acts of abstraction. Somewhere along the line a rule had to come in to enable us to obtain more numbers, in the natural order.

From:
Paul Benacerraf (Logicism, Some Considerations (PhD) [1960], p.165)
|
|
A reaction:
Follows on from Idea 13411. I'm not sure how Russell would deal with this, though I am sure his account cannot be swept aside this easily. Nevertheless this seems powerful and convincing, approaching the problem through the epistemology.

We must explain how we know so many numbers, and recognise ones we haven't met before [Benacerraf]
|
|
Full Idea:
Both ordinalists and cardinalists, to account for our number words, have to account for the fact that we know so many of them, and that we can 'recognize' numbers which we've neither seen nor heard.
|
|
From:
Paul Benacerraf (Logicism, Some Considerations (PhD) [1960], p.166)
|
|
A reaction:
This seems an important contraint on any attempt to explain numbers. Benacerraf is an incipient structuralist, and here presses the importance of rules in our grasp of number. Faced with 42,578,645, we perform an act of deconstruction to grasp it.

|
If numbers are basically the cardinals (Frege-Russell view) you could know some numbers in isolation [Benacerraf]
|
|
Full Idea:
If we accept the Frege-Russell analysis of number (the natural numbers are the cardinals) as basic and correct, one thing which seems to follow is that one could know, say, three, seventeen, and eight, but no other numbers.
|
|
From:
Paul Benacerraf (Logicism, Some Considerations (PhD) [1960], p.164)
|
|
A reaction:
It seems possible that someone might only know those numbers, as the patterns of members of three neighbouring families (the only place where they apply number). That said, this is good support for the priority of ordinals. See Idea 13412.

Some kinds are very explanatory, but others less so, and some not at all [Devitt]
|
|
Full Idea:
Explanatory significance, hence naturalness, comes in degrees: positing some kinds may be very explanatory, positing others, only a little bit explanatory, positing others still, not explanatory at all.
|
|
From:
Michael Devitt (Natural Kinds and Biological Realism [2009], 4)
|
|
A reaction:
He mentions 'cousin' as a natural kind that is not very explanatory of anything. It interests us as humans, but not at all in other animals, it seems. ...Nice thought, though, that two squirrels might be cousins...
