@Deftil,
What do you think are the toughest philosophical questions to answer? I'm not looking for your answers (that would be too much for one thread), but I'm looking for your specific questions. What philosophical questions do you find yourself unable to answer? Which ones, if any, do you think are impossible to answer?
Questions:
1. could god make a 10 dollar bill that is not counterfeit?
2. since an oak tree, by definition, has to come from an acorn that came from an oak tree, could god make one of those if he isn't an oak tree?
3. a squirrell and a man are moving around a tree in the same clockwise direction but on opposite sides of the tree never seeing each other. which one is circling the other?
4. (and of course) There are two errors in in this sentence. (is it true or false?)
