I say at the start of the OP that I'm assuming the first cause is God. — Devans99
Of course not, but Zeno's arguments highlight the nonsensical nature of the continuum - that is the purpose of the arguments - not to prove an arrow is motionless. — Devans99
If you don't believe that an arrow in flight must be motionless, then why do you believe that there must be a first cause?
Looks like the same kind of logic to me — S
Seriously, can you present a logical argument for a universe without a first cause? — Devans99
If Homer can walk to the end of a path, then the universe can be without a first cause. — S
Suppose Homer wishes to walk to the end of a path. Before he can get there, he must get halfway there. Before he can get halfway there, he must get a quarter of the way there. Before traveling a quarter, he must travel one-eighth; before an eighth, one-sixteenth; and so on. — S
Your argument for the necessity of a first cause uses the same logic — S
We have a timeless, powerful, intelligent first cause — Devans99
Only if cause and effect applies in this scenario — Pattern-chaser
What do you have to back up this bald assertion? — Devans99
So homer cannot walk to the end of the path so by your logic the universe has a first cause? — Devans99
No it does not. It's a topological argument. First cause is topologically connected (casually connected) to every other cause. Take away the first cause and everything else ceases to exist. It has nothing to do with infinitesimals. — Devans99
That's like you reasoning that for the universe to have existed the time that it has done, then it must have existed half of that time, and half of that time, and half of that, and so on. Except that you then just randomly assert without reasonable justification that there must have been a first cause. — S
You will see that arguments B, C and E do not use cause and effect as an axiom. — Devans99
The point is that your Homer example demonstrates that space is discrete. So it is a valid argument that leads to the valid conclusion: that space is discrete (not that Homer can't walk the path). — Devans99
I never reason like this. Your example has a completely different structure to my argument. — Devans99
I think the start [o]f time requires a first cause... — Devans99
You really want the logic to work in the special case of God, even though it doesn't work elsewhere — S
Your reasoning against an infinite regress is just of the sort that Homer has to get halfway, and half of halfway, and so on, and then you randomly assert a first cause, which would be like randomly asserting a final destination. — S
Please tell me where cause and effect does not hold? — Devans99
My reasoning against an infinite regress is that it has no starting cause, so that the 2nd cause cannot be defined (because it is determined by the first cause), nor the 3rd, and so on. That is a topological argument that the start is causally connected to the rest of the infinite regress. It does not rely on infinitesimals. — Devans99
...while I don't think that my understanding of time is sufficient to justify a cause for it. Or not. — Pattern-chaser
It seemingly does hold, and that's the problem you have to contend with. — S
The logical resemblance is crystal clear. It's just a backwards chain and a forwards chain. You go into detail in a similar way that Zeno's paradoxes do, with a similar logic, and then at an arbitrary point, you randomly assert your dogma of a first cause, like the parallel conceivable dogma of a final destination. — S
Time had a start. — Devans99
Time had a start. Things just don't start themselves (just like it is impossible to create one's self). — Devans99
If cause and effect holds then there must be a timeless first cause. — Devans99
Honestly you are talking about the Summa Theologica, one of the greatest works of philosophy, and calling it dogma. — Devans99
