Hi, Esquire.
If Hume’s problem of induction is valid, then virtually nothing is knowable; at least if you believe (as I do) that all knowledge comes to us through the senses.
Let’s be more precise: When it comes to the external reality, then there is always some degree of uncertainty. We must always be aware that there can be an error, either in the observation, or the interpretation. This, of course, does not invalidate the inductive method, it merely cautions us to be aware of the possible problems, or exceptions. As such it is a practical “warning”. On the other hand, in the formal, axiomatic systems, we know with absolute certainty that propositions from the axioms are valid (by definition). The Pythagoras theorem will never be invalidated.
The objection simply warns us not to elevate the “practically” certain method to the rank of “absolutely” certain, metaphysical principles. Yes, we can practically say that physical causation is universal. A billiard ball will not start rolling, unless it is pushed by the cue-stick. But from this, practical observation it does not follow that there cannot be an “uncaused” event. As a matter of fact, the “emergence” of virtual particles look like a good example of uncaused events.
Not even the laws of logic are known a priori.
Without the laws of logic there can be no reasoning. If “A is A” would be denied, then there would be no “true” or “false” propositions.
Are we going to question those too? Craig’s argument is that there is no good reason to jettison the laws of causality (or the laws of logic) simply because we are speaking of the universe. I would put it this way: if the objector to the law of causality wants to reject all human experience in this regard and make a special exception for the beginning of the universe, then there needs to be a reason. Craig argues none are forthcoming.
The reason is simple. The universe is not an object, it is abstract set. It is a collection of physical objects. The fallacy of composition is applicable here. Again precision is important. The fallacy of composition does not say that it is incorrect to generalize from the particular to the general, it merely states that such
generalization cannot be “automatic”, it needs to be established. (Example: valid generalization: “the floor is composed from white tiles, therefore the floor is itself white”. Incorrect generalization: “the floor is composed of square tiles, therefore the floor is itself square”).
The last sentence is correct. The explanations of physics break down at the singularity. But one tends to wonder how this helps your argument. Why? Because Craig would adamantly reject the truth of the first sentence. He is speaking about efficient cause, not material cause.
As opposed to “
inefficient” causes? Sorry, this thomistic concept is also rejected. Causation is experienced as a physical interaction. True it is not an absolute rule, theoretically there could be exceptions, but they need to be demonstrated. People who believe in the “paranormal” are welcome to demonstrate such non-physical causation using their “mental powers”.
Yet I have no problem using your nomenclature, that the current form of the universe had a beginning, As long as the universe in which we find ourselves had a beginning, no problem. You can certainly assert a multiverse theory, but it still doesn’t have any implications for this particular premise. Although it might have some implications for what is the cause of our universe.
I am not interested in the multiverse concept. My stance is simple. When it comes to the universe, concepts like “temporally before” or “spatially outside” or “externally caused” are nonsensical, undefined and undefinable. The universe is all there is, and one cannot speak meaningfully of “creation”.
Even if they speak of a lack-of-beginning of our universe, it seems that nobody can really say anything about “the universe.” My observation is that if the fallacy of composition applies, then nobody can speak about the origins of our universe at all; and any discourse concerning it is nonsense. Is that your view?
I explained about the problem of composition above. And, indeed to speak of the “origin” of the universe is an exercise in futility. The universe is the ontological foundation of existence, and to speak of “outside” or “before”, etc… exactly as unacceptable as speaking of an object that resides to the north from the North Pole.
Sometimes people state that the universe “does not explain itself”. Apart from the horrible linguistic form (the universe is not a teacher to explain anything

), this objection is unacceptable. If one wishes to avoid the infinite regress, there must be a “starting point”. For theists this starting point is God, unexplained and unexplainable. For the atheists it is the universe. The theistic starting point is more “complicated”. That would be no problem, if only it had “explanatory power”. But it explains nothing. As I said before: “an unknowable being using unimaginable means made the universe somehow happen”. That is not an explanation.
