Excellent Points, But Why Not Using Prima Via?

My New Favorite Argument for God

3:00 You were doing very fine on Secunda Via, not first mover, but generalised to first cause, including of non-movement.

Then you said "even if the chain went on indefinitely" ... it couldn't. If it did, it would lack a hook to the roof, and therefore the werewithal to keep the chain links and the chandelier up.

8:07 Now you have transitioned to Tertia Via.

For non-Geocentrics, that one tends to get more popular than Prima Via ... can you detect why?

Obviously, I agree with Secunda and Tertia Via too.

9:41 If you grant Geocentrism and Tychonian orbits, personal is actually a given through this argument.

The moving of the universe round and round couldn't be an irrational simple propensity, since circular movement requires some aim.

And if smaller personal beings are concerned with Tychonian orbits, it would take a personal being to command them.

14:50 A final point. The ecosystem we live in, to St. Thomas, was a matter of Prima Via, because the Zodiac going around us in close to 24 hours and Sun going through the Zodiac in a year and Moon going through the Zodiac, not so much in herself as in relation to the Sun, is actually keeping us alive.

But the Zodiac is in the sphere of the Fix stars. So, to St. Thomas, even Sirius, Vega, Aldebaran are in our single ecosystem. This is, if you go to Q11, A3, corpus, the third way in which St. Thomas establishes that God is actually one. And that third way is the only that builds directly on the five ways in Q2. The first and second ways of establishing God's unity build on QQ 3 and 4.
