An aggregate in which order does not matter I call a 'set' [Bolzano]
|
|
Full Idea:
An aggregate whose basic conception renders the arrangement of its members a matter of indifference, and whose permutation therefore produces no essential difference, I call a 'set'.
|
|
From:
Bernard Bolzano (Paradoxes of the Infinite [1846], §4), quoted by William W. Tait - Frege versus Cantor and Dedekind IX
|
|
A reaction:
The idea of 'sets' was emerging before Cantor formalised it, and clarified it by thinking about infinite sets. Nowadays we also have 'ordered' sets, which rather contradicts Bolzano, and we also expect the cardinality to be determinate.

Laissez-faire individualism doesn't work, especially in troublesome times [Keynes]
|
|
Full Idea:
It is obvious that an individualist society left to itself does not work well or even tolerably. The more troublesome the times, the worse does a laissez-faire system work.

From:
Maynard Keynes (The General Theory of Employment [1936]), quoted by Ian Dunt - How to be a Liberal 7
|
|
A reaction:
I thought I was a Communitarian, but I may be a Keynesian Liberal, committed to a safety net welfare system. I haven't quite decided yet. Political philosophy is hopeless, if the ideas actually have to be implemented. What is the criterion of 'work'?
