Analytic/synthetic and a priori/ a posteriori distinctions?
Why refrain from asking the next questions that are directly related to these questions and distinctions already answered within the PhilPapers survey, namely: Are there analytic a priori judgments or statements? Are there synthetic a priori judgments or statements (e.g., a straight line is the shortest distance between any two points)? Synthetic a posteriori? And (the anti-Kantian) analytic a posteriori?
Depending upon one's view of contradictions, there could be a set of valid arguments supporting a fourth set of analytic a posteriori judgments or statements. Anyway, it would be interesting to see if 1-5% made that distinction or sided with Kant against it. I doubt it would be 0% though, and it is important to see how many would make the synthetic a priori distinction contra Hume, which has important implication in ethics and metaethics.
