3. The Professor did not know the difference between the qualitative and quantitative infinite. I used a deductive argument to show that the universe began, and therefore was preceded by its non-existence. The deductive argument I used can be summarised in the following way:
i. An actual infinite cannot exist
ii. An infinite history of past events is an actual infinite
iii. Therefore, an infinite history of past events cannot exist
iv. Therefore, the universe is finite
v. Therefore, it had a beginning
I argued that this deductive argument is based on the quantitative infinite not the qualitative one. Professor Krauss used the ratio of a circle's circumference to its diameter to try and show that the actual infinite exists. I responded by saying that he just described the qualitative infinite, not the quantitative infinite. For example you can actually measure the diameter and the circumference, and the ratio he referred to is qualitative, in other words it is not based on discrete parts you can quantify. A ratio is a relationship between two numbers, the fact that it is a relationship highlights its qualitative nature. Professor Krauss change the subject when I explained this to him.
http://www.facebook.com/HamzaAndreasTzortzis/posts/580338305309941Hamza says that an actual infinite can not exist, I was wondering whether this includes GOD, as a number of his attributes are infinite. So by his very own deductive reasoning that God does not exist
i. An actual infinite cannot exist
ii. Gods length of existance is an actual infinite
iii. Therefore, an infinite God can not exist
iv. Therefore, the God is finite
v. Therefore, it had a beginning
So the question begs what caused this God, if everything that begins has a cause, then this mean a infinite regress occurs, but those can't exist, therefore God does not exist.
This is just a quick summary of how i understand this argument. Is my reasoning valid? Corrections would be appreciated.
This is the first time I've come across this infinity argument. Anyone got any useful info on this sort of apologetics.
I found this pretty funny. Tortoise got Krauss's twitter username wrong and called some random woman a liar.
(Clicky for piccy!)she does look like a liar
