(Previously) ...Next, the mea culpa. It concerns Badiou's position on the Continuum Hypothesis. In 1878 Georg Cantor offered a hypothesis about the continuum, essentially a hypothesis about the nature of continuous number. More specifically the hypothesis concerned Cantor's famous two sizes of infinity and the relation between them. After establishing the position of the smaller infinity, the infinity of rational or arithmetical number, Cantor hypothesized that the "next highest" number would be his larger infinity, the infinity of real or geometric number. I write next highest in scare quotes because the question of size and even counting itself stops making intuitive sense after transgressing the threshold of finitude.
If you're looking for a more technical statement of the CH, here is a helpful one by Mary Tiles from her excellent book The Philosophy of Set Theory: An Historical Introduction to Cantor's Paradise (p. 1):
"2ℵ0 = ℵ1, which has come to be known as Cantor's continuum hypothesis, thus says that the number of points on a line is the second infinite cardinal number: there are none in between ℵ0 and 2ℵ0."
Okay, so the CH has a long history in mathematics and I'll be the first to admit that my knowledge of the underlying math is wobbly at best. But let's establish the basics at the outset. Continue reading
