why is infinite regress impossible

Powered by Discourse, best viewed with JavaScript enabled, : The views and opinions expressed in these forums do not necessarily reflect those of Catholic Answers. I don’t agree with this part either. Only if the series were finite would it be impossible for there to be something if there were no first cause or uncaused cause. The regress ends in self-evident truths, the axioms of geometry, for example (Foundationalist view) Continue adding intermediate causes, and there is still an invalid causal series if the first cause is removed after each intermediate is added to the chain ad infinitum. Infinity simply doesn’t exist for a finite universe. I'm hoping this version of the question will be more clear and easier to respond to. If one regresses to infinity in looking at intermediate reasons, the fully sufficient reason will never be found, since none of the intermediate links provides the complete reason for the final effect. Therefore there must be a first cause of everything. In philosophy, the infinite regression phenomenon frequently … regardless, infinite regress is impossible simply by virtue of the 'turtles all the way down' problem. If all such causes are merely intermediate, then some causal activity is passing through the entire chain, but no member of the chain can explain it. June 28, 2018, 6:32pm #22. If we remove the first cause, of course, the situation is invalid. In these cases, an infinite regress argument can show us thatwe have reason to reject a theory, but it is not because the theoryyields a regress per se, but rather because it has this otherbad feature, and the regress has revealed that. Is it possible to reach from 1 to zero? Others think there is, but that all truths are demonstrable. to wit, if god made the universe, then who made god, then who made the maker of … To argue for an infinite regress of events, you are by definition arguing for an an actually infinite number of a finite amount. Dr. Craig, I cannot thank you enough for your apologetics work. There are things as actual number of things. To speak of an an actually infinite quantity or number is to speak of something that is made of finite parts or irreducible points that add up to an actual infinite. What is his argument? The regress is infinite but virtuous. It’s indefinable.There is always a finite amount no matter how large the quantity or how many numbers you add. Theism I've read in defense of the second premise of most cosmological arguments that in an essentially ordered series infinite regress is impossible because if it did then there would be no first cause and therefore no source of causal power. He was looking for the *first* cause, something that is 'necessary'. For Plato, infinite regress is an impossibility. It is called intermediate precisely because it is passing along a reason that it itself does not fully explain. Can someone please explain to me why an infinite regress of causes is impossible? Zeno’s paradox shows you can have an infinite number of steps (each one becoming smaller than the previous) in a finite interval. This means that any proposition whatsoever can be endlessly (infinitely) questioned, resulting in infinite regress.It is a problem in epistemology and in any general situation where a statement has to be justified. IWantGod. That is, since each premise is contingent on some reason, we then require another premise to justify that reason. Otherwise, the chain would stop right there. Beyond that, the causal chain could loop back on itself or do all kinds of wonky stuff, too. Thus, there must be a first sufficient reason, which is its own reason – otherwise the principle of sufficient reason itself would be violated. William Lane Craig . Philosophy. Now, to reconsider that chain of intermediate reasons described above, we see that the same problem arises. I argue that Aquinas has good reason to hold this claim given his conception of causation. When St Thomas dismissed an infinite regress of causes, he did so, not because he thought there could never be an actual infinity of ‘things’ or ‘events’ (he was much smarter than that); he dismissed it on account of the fact that an infinite series of things, events, causes, or whatever, cannot explain something existing currently. Well our known universe had a definite start time. There is not an amount, quantity, or number of things, that can add up to an infinite because an infinite is quantitatively indefinable. Think of 1/x where we gradually go toward x=0. The problem is that each prior reason is not really sufficient unto itself. Were it not for the “need” to conform timelike intervals to eternalism’s false hypothesis, the obvious reading of human experience and scientific observation within the same local world line would be that real causality occurs in “normal” time. Infinite regress of causes is impossible So, 4. 1 … Infinite regress is impossible because infinity is an irrational term when appled to a finite universe. What makes infinite regress impossible? Apologetics. Aquinas does not explain why there cannot only be secondary causes. The Infinite causal regress is an important issue in dealing with the cosmological argument, especially the Kalam version, and the argument form final cause. There is no sufficient reason in an infinite chain of causality and there is no need for it so it is meaningless to argue based on it. Why infinite regress is impossible? Because he holds that effects For the most part I've just accepted that infinity is impossible, since it seems to be the accepted view. Explain. The reason is that an instrumental chain of causes (a chain of sticks used to push a rock) can’t get started by itself. Infinite Regression. The end time is still a great unknown. A Production of Word on Fire, "Come now, let us reason together." Because by definition infinity does not end. But that is impossible. But is it? But there is no otherwise. Solely a first cause that initiates the entire chain can do that – a first cause uncaused. - Isaiah 1:18. Infinity simply doesn’t exist for a finite universe. Are Metaphysical First Principles Universally True? This article assumes the evident truth that real causes produce real physical effects in time, as human beings normally conceive it, that is, with the past no longer existing and the future not yet existing. Several versions of the Cosmological Argument (Motion and Causality) make it one of their premises that infinite regress is impossible. What is his argument? Each one leaves some of the needed reason lacking. Because there is no such thing as an actually infinite number of something. How can the God of the Philosophers be the God of Abraham, Isaac, and Jacob? More later inshallah. You are just proving that infinity cannot be reached which this is different from that infinity does not exist. But it still stands that the infinite causal chain must have a first cause. Atheist Physicist Sean Carroll Answers…. If an infinite number cannot be achieved i fail to see how an infinite regress could actually be achieved. This is why it's a logical flaw. From this article, which I just found by Googling “why is an infinite regress impossible?”…. Why Does the Universe Exist? Again, this is not presented as proof of God’s existence, but merely as proof that an infinite regress among essentially subordinated causes is metaphysically impossible. If yes then 1/x is an actual infinity. An Infinite regression is a loop of premises that continue on in ad infinitum. Infinite regress is impossible because infinity is an irrational term when appled to a finite universe. It is infinite otherwise it is bounded with by a boundary and that boundary is bounded by… etc. I've been faithfully using your podcasts, debates, books and articles for about 4 years now. However brief, this summarization provides one of the first contexts for the cosmological argument and its use of infinite regress. Why are philosophers so concerned with the "infinite regress"? Following some unpublished work of Gregory O'Hair, David Armstrong identifies and diagrams several possible ways to escape the Skeptic's infinite regress, including: Skepticism - knowledge is impossible. There is only ever the potentially infinite number. You are just proving that infinity cannot be reached, I think an actually infinite number is meaningless because there is no actual quantity that can be said to be infinite.
