The existence of a non-even function of order 1 is equivalent to the Continuum Hypothesis (i.e., the statement that 2^{\aleph_0} = \aleph_1 ). Causal set theory, by contrast, is purely bottom-up at the classical level. Accordingly, the Language of Set Theory (in this case using $ZF$ axioms) is built up with the aim to express all mathematics. 999, Gerbert was elected Pope Sylvester II. By the 1950s, after the work of Gödel, this problem, known as the "Continuum Hypothesis," had become the central one in the set theory. It is true that some things are not decided by $mathsf{ZF}$, such as the Continuum Hypothesis. Lacan was interested in an ostensible fact of linguistics, according to which cardinals come into language before ordinals. Paradoxes like this are what really drive set theory, much of which centers on defining rules for sets and how they work so that we don't just go around assuming certain sets exist when they clearly can't—andso that we can still use the valuable logic and math of sets even when we can't prove that the stuff we're sticking The downstream effects of these assumptions isn't always obvious — it wasn't obvious that the axiom of choice implies the continuum hypothesis. In the context of classical spacetime, the hypothesis of top-down causation is that causal relationships among subsets of spacetime are not completely reducible to causal relations among their constituent events. In 1963, he proved that the axiom of choice and the continuum hypothesis are independent of the other axioms of set theory. In causal set theory, causality is modeled as an irreflexive, acyclic, locally finite binary relation on a set, whose elements are viewed as spacetime events. Badiou had already addressed the “continuum hypothesis” in maths in his Theory of the Subject. But I've only seen those discussed in the context of the set theory of the real line.

The difference between cardinal and ordinal ordinarily implies a distinction between the question of how many, e.g., 7 stones, and the question of order and hierarchy, e.g., 7th son. It's part of Cantor's set theory.
