我们还是不能在屋子里进行鸟类学研究 --对亨佩尔消解性解悖方案的质疑

亨佩尔发现的确证悖论表明,一只粉红色的鞋确证假说"所有乌鸦都是黑的",这意味着我们在屋子里不用出门就可以进行鸟类学研究,但这是违反我们的直觉的.因此,亨佩尔提出一个消解性解决方案来进行辩护.这种消解主要是通过保留等值条件和抛弃尼科德标准中的"非相干性"条件进行的.保留等值条件具有较强的特设性,因此不能令人信服;保留"非相干性"条件不具有导致悖论的必然性,抛弃它也不必定能避免悖论的产生.因此,按照解悖的罗素-策墨罗-哈克标准,亨佩尔方案不具备一个良好解悖方案的合法资质.

We Still Can Not Study Ornithology inside the House --An query on Hempel's dissolution

The confirmation paradoxes that Hempel discovered shows that a red shoe confirms the hypotheis that all ravens are black, which implies we can do the ornithological study inside the door. It is very counterintuitive, so Hempel proposed the dissolution to them. This dissolutive tragedy is to keep the Equivalence Condition and discard the Irrelevant Condition of the Nicod Condition. To keep the Equivalence Condition is very ad hoc, so it isn't convincing. However, to keep the Irrelevant Condition doesn't cause any paradoxes necessarily; to discard it can not escape paradoxes yet. So Hempel's dissolution can not be certified as a good one.
