Cosmological Argument Recap 1. On your whiteboards summarise a basic version of the Cosmological argument. 2. Then use your phones to go to kahoot.it and join the room: Think carefully about what mistakes you made on the quiz before Christmas, and what we covered to do with the cosmological argument. Hume’s Four Criticisms What were the four criticisms Hume made of the cosmological argument? 1. Why God? 2. No such thing as necessary beings 3. Cause is a human construct 4. Fallacy of Composition Hume’s Four Criticisms Did any of these arguments have successful responses? 1. Why God? 2. No such thing as necessary beings 3. Cause is a human construct 4. Fallacy of Composition Returning to Copleston Vs Russell Whiteboards – Can you remember the version of the argument that Copleston puts forward? • Things in the universe exist contingently • Something that exists contingently has (and needs) an explanation of why it exists; its existence is not inevitable • This explanation may be provided by the existence of some other contingent being. But then we must explain the existence of these other contingent beings • To repeat this infinitely is no explanation of why anything exists at all • Therefore, what explains why contingent beings exist at all can only be a noncontingent being • A non-contingent being is one that exists necessarily C: This necessary being is God Russell’s Criticisms 1 Which of Hume’s Criticisms is Russell echoing here?: “This raises a great many points and it's not altogether easy to know where to begin, but I think that, perhaps, in answering your argument, the best point with which to begin is the question of a Necessary Being. The word "necessary" I should maintain, can only be applied significantly to propositions. And, in fact, only to such as are analytic -- that is to say -- such as it is self-contradictory to deny. I could only admit a Necessary Being if there were a being whose existence it is self-contradictory to deny.” - Russell https://www.youtube.com/watch?v=hXPdpEJk 78E – 4.59 Russell’s Criticisms 1 – No Necessary Beings Russells first criticism is one of two he borrows from Hume: Both Aquinas and Copleston assume that there can be a necessary being. But Russell disagrees, arguing that only propositions can be necessary, not beings. Necessary truths are ones whose opposite implies a contradiction, but there is no being whose non-existence implies a contradiction. Although they may not be true, claims about existence such as “Barry does not exist” always make sense- they are not selfcontradictory because they are synthetic rather than analytic (we’ll see much more on this idea later). So even talking about the idea of a necessary being is mistaken. Does denying the existence of any of these things create a contradiction? Russell’s Criticisms 2 Which of Hume’s Criticisms is Russell echoing here?: “Because I see no reason to think there is any. The whole concept of cause is one we derive from our observation of particular things; I see no reason whatsoever to suppose that the total has any cause whatsoever. I can illustrate what seems to me your fallacy. Every man who exists has a mother, and it seems to me your argument is that therefore the human race must have a mother, but obviously the human race hasn't a mother -- that's a different logical sphere.” - Russell Russell’s Criticisms 2 – Fallacy of Composition • Russell points out that Copleston moves from talk of individual contingent things to the group of all contingent things. Whilst individual contingent things may need an explanation, that doesn’t mean that the group does. • When someone wrongly attributes a property of individual items to the group of items as a whole, this is known as the fallacy of composition. It is simply not always true that the whole group has the same properties that the individual parts do. What examples have we seen to illustrate this? A Response to Russell The problem is that sometimes properties of the parts do apply to the whole: I might break this table down and look at the properties of it’s individual parts: Brown, Wooden, Flammable etc. As a result I would be able to say that the table as a whole is brown, wooden and flammable and I would be right, the fallacy of composition does not apply here. Could we say the same of the universe? Each part is contingent and requires a cause, so to does the whole? Russell’s Criticisms 3 – The Unnecessary Question Now we move on to Russell’s more unique criticisms of the argument: Building on Hume and the fallacy of composition – Russell criticises the idea that we are looking for a cause of the universe as a whole at all. He argues that we derive our idea of cause from our experience of particular things and therefore, since we cannot experience the universe as a whole, we cannot therefore talk about it’s cause. “I should therefore say that the Universe is just there, and that’s all.” Russell’s Criticisms 3 – The Unnecessary Question Now we move on to Russell’s more unique criticisms of the argument: In arguing this, Russell is denying the very point of the cosmological argument to start with – he doesn’t think we need great, all encompassing answers for existence. He does not think the universe is crying out for an explanation. Russell does not feel the need Copleston does to answer the question “Why is this all here?” “I should therefore say that the Universe is just there, and that’s all.” Russell’s Criticisms 4 – Uncaused Events A final criticism Russell offer’s is one we’ve seen before, supported by modern science: “I don't want to seem arrogant, but it does seem to me that I can conceive things that you say the human mind can't conceive. As for things not having a cause, the physicists assure us that individual quantum transitions in atoms have no cause.” - Russell Russell’s Criticisms 4 – Uncaused Events A final criticism Russell offer’s is one we’ve seen before, supported by modern science: • Although quantum physics was only just being discovered at the time of the radio debate, Russell uses the example of quantum particles which behave indeterminately and appear to be uncaused. • It is accepted by most (but not all) scientists that some of the actions and properties of these particles have no cause, that they do not have definite properties prior to being measured. • This is known as the Copenhagen Interpretation. Russell’s Criticisms 4 – Uncaused Events What does this mean? • If on some sub-atomic level, there are particular events that have no cause – is it not possible that this could explain the start of the universe? That our existence is ultimately based on one of these chance, still-contingent, uncaused actions, rather than a necessary God? • If this is a genuine possibility then it massively undermines one of the key premises of the causal cosmological arguments: the certainty that everything must have a cause. Russell’s Four Criticisms Use pages 287-289 in the textbook to make sure you have these criticisms recorded: 1. No necessary beings 2. Fallacy of Composition 3. The unnecessary question 4.

Anyone who can will get some sweets (because philosophers are apparently not concerned with healthy eating). Remember, you will need to know the answer yourself to make sure I’ve got it right or wrong!
