Kalam Cosmological Argument - Part 2 - William Lane Craig

COSMOLOGICAL ARGUMENT by William Lane Craig

1. Whatever begins to exist has a cause.

2. The universe began to exist.

2.1 First Philosophical Argument

2.11 An actually infinite number of things cannot exist.

2.12 A beginningless series of past events involves an actually infinite
number of things.

2.13 Therefore, a beginningless series of past events cannot exist.

2.2 Second Philosophical Argument

2.11 An actually infinite collection of things cannot be formed by
successive addition.

2.12 The series of past events is a collection of things formed by
successive addition.

2.13 Therefore, The series of past events cannot be actually infinite.

2.3 First Scientific Confirmation

2.4 Second Scientific Confirmation

3. Therefore, the universe has a cause.

4. If the universe has a cause, it is uncaused, beginningless, changeless, immaterial, timeless, spaceless, unimaginably powerful, and personal.

4.1 The cause is uncaused.

4.2 The cause is beginningless.

4.3 The cause is changeless.

4.4 The cause is immaterial.

4.5 The cause is timeless.

4.6 The cause is spaceless.

4.7 The cause is unimaginably powerful

4.8 The cause is personal.

5. Therefore, a personal Creator of the universe exists, who is uncaused, beginningless, changeless, immaterial, timeless, spaceless, and unimaginably powerful.

Craig's argument is wrong. A hotel with infinite number of rooms could accommodate all the guests including potential guests. You could never have 100% occupancy in a hotel with infinite number of rooms.

[drcraigvideos]

@vincyjojo1 You're not listening to the audio close enough are you. We're talking about actualy infinites, genius.

[xdairybastardx]

Why do these people have such a difficult time understanding what he's saying? I understood what he said instantly the first time I heard it. Is that just me? :/

[drcraigvideos]

@xdairybastardx Nope. Usually atheists (especially youtube atheists) already have their minds made up even BEFORE they hear the Kalam Cosmological argument. In reply, they'll say the most incredibly idiotic things, from "nothing can do something" to "what caused God then". Trust me, I've heard them all.

[MrRyans777]

@drcraigvideos It's also because of their ego and their pride lol

[2rainmalt]

@drcraigvideos time that is potentailly infinite equals space which equals your actual. 

[Intellectual4God]

dang what a long video, that blew me away i have to say i learned a lot, but out of the 42minutes theres one thing i wanted to go back and look at because i couldnt remember and it would be hard to find

is space potentially infinite, actually infinite, or finite

also

the universe is potentially infinite in volume correct?

[Satarack]

@TheCopaceticMan As a result, actual infinities are indistinguishable. We can't tell the difference between one actual infinity and another. With potential infinities we can; because we can see difference in the rate at which they tend toward infinity, and can describe it. But this is not possible with an actual infinity since it's value is infinity everywhere.

So when we encounter infinity - infinity = ? we can't tell if the difference is zero, less than zero, or greater than zero.

[Satarack]

@TheCopaceticMan An Infinite set is not an actual infinite, it's a potential infinite. You have to understand the difference between these two things first.

A potential infinite is a set that goes from i to N where N=infinity. This means that for every i, the set has a finite value, but as the number of i increases toward infinity, the value of the set goes toward infinity.

An actual infinity is an infinity at all points of i. When i=1 the set is infinity, when i=100 the set is infinity.

[vincyjojo1]

I do understand the difference between actual and potential. Craig says that actual does not exist. To demonstrate that he uses Hilbert example. What I am saying is the the infinite room analogy is absurd.

Let me ask you a simple question. On what basis Craig says that actual does not exist. He might say that there is no evidence for the actual infinite in our natural world. Is absence of evidence evidence of absence? The "logic" I used above is Craig's own favorite phrase!!!!

[TheCopaceticMan]

How is subtracting an infinite from an infinite a contradiction? That sounds to me how infinite sets work. I don't see a contradiction there. Any further elaborations?

[ChristusVlCTOR]

@marveymarker I'm not sure where you got that from, but it is my understanding that because of the sheer gravity of Space, that the further you go, it eventually begins to curve back on itself.
