While Aristotle's view on knowledge may well be convenient, I would point out that based upon that view we knew the earth was the center of the solar system. So I wouldn't call it a dependable method if we are looking for any degree of accuracy.
If you are wrong about some things, should we conclude that you are then wrong about all things? The discussion was not about Aristotle's Ptolemic view of the solar system. That he was subsequently proved to be in error about that does not negate what he was right about. Aristotle was restricted to the physical restrictions of his time and culture but nevertheless contributed more to the understanding of basic science than any other figure of his time. He is basically the father of the modern scientific method i.e. a statement of a concept, a definition of terms, a statement of the rational that goes into the analysis, observation, argument on how well the concept is justified via observation, and finally what could be concluded.
He had no means to measure time or speed and he dismissed all concepts of invisible force because it was unobservable so he did not conceive of gravity. Drawing on Platonian reasoning, he concluded that things fell to the ground and the moon orbited the Earth because that was their nature. But even with such limitations in understanding, he proved that infinite linear motion and voids and infinite velocities could not exist on Earth and came up with the theory that time was even flowing, infinite, and the same everywhere. He was able to make amazing contributions to physics that laid a groundwork for Galileo, Newton, and even Einstein to build on. We can learn much from Aristotle's manuscripts. And as for his observation he coined as infinite regress which is the only reference I made to Aristotle in my argument, I don't think anybody can argue with the concept.
So returning to the thesis of the thread, the syllogistic argument:
Everything that exists must have a beginning.
The universe exists.
Therefore the universe had a beginning and some call that beginning God.
Aristotle's infinite regress concept then kicks as to where God came from.![]()
When it came to the idea that knowledge does not require evidence, he was flat out wrong. He may have been right about other things, but not about this.
Ok, to the argument.
Aside from assertion, how do you know everything that exists must have a beginning? Everything that currently exists, as far as we know, has always existed.
Having a bit of reading comprehension problems today? I did not say that Aristotle said knowledge did not require evidence. That would be absurd. What I said he said is that knowledge does not have to be demonstrable in order to be knowledge. A very different thing.
And I accept the reasoned conclusion that everything must have a beginning because there is zero evidence, zilch, nada, nothing--no eye witnesses, no testimony, no theory put forth by anybody--that suggests otherwise.
I am notoriously thick. What is the difference between not being demonstrated and not having evidence?
There is an equal amount of evidence which suggests everything must have a beginning.
Including god?
Certainly.
