Document Summary
Quantifiers and scope (specify the amount/thing in question) Quantifier scope: the parts of a statement governed by the quantifier (range of the sentence that the quantifier applies to) In each case, the premise can be true, but the conclusion can be false. If we interpret the everything in 2. 1 as referring to everything taken as one big thing then the inference is not fallacious. 2. 1: the totality of all things as a unit, is capable of non-existence. 2. 2: if the totality of all things as a unit, is capable of non-existence, then there is some time at which nothing exists. Still relies on the assumption that anything capable of not existing doesn"t exist at some time. Suppose the universe is something necessary, but which requires a cause for its necessity. Granting the possibility of an eternal universe what is left to explain. Why do we need to posit a cause of the necessity, if necessity here just means.
