Thanks for your help on my previous post. I have another question open to anyone.

This is the first argument I have presented in my paper and I am trying to figure out which premise would be the easiest one to object to. (Also, I THINK it's valid, but if it's not please let me know!) So, which premise looks the easiest to object to and why?

1. If there is time, then there is a 4th dimension.
2. There is time.
3. ,', There is a 4th dimension (MP).
4. If there is a 4th dimension, then all things have temporal parts.
5. "3"
6. All things have temporal parts (MP).
7. If an object has temporal parts, only one object exists at any place at any given time.
8. "4"
9. ,', Only one object exists at any place at any given time.

Well, first off, you don't need to state 3 or 4 again - so leave out premises (5) and (8). The premises in a formal argument can go in any order - rearrange them all you want, and its still valid. Generally, however, the premises which lead up to a subconclusion or a conclusion are placed somewhere (anywhere) between the subconclusion or conclusion.

I would object to premise (7). Why should it be the case that if an object did have temporal parts, then only one object exists at any given place at any given time? As I explained in another one of my recent posts, the only reason that objects are kept from occupying identical positions in space-time is due to the forces between objects on the subatomic level. Neutrinos, which do not experience any force other than the weak nuclear force (and gravity of coruse, though barely - they're mass is barely detectable), are free to pass through any matter they wish and do, therefore, occupy the same space as other matter without violating any law of physics. This is one of the reasons that neutrinos are so hard to detect - there are probably thousands of them passing through you right now, but you'd never know it. In any case, here's a web site on neutrinos that you might find a useful introduction to them:

The above web site is from the Fermi National Accellerator laboratory in Chicago. However, one piece of information contained on it is outdated - it is now known that neutrinos do, indeed, have mass, as has just been discovered as Fermilab's MINOS detector. See for more on that.
