Interestingly, both "idealist" and "materialist" philosophies tend to say that the "first cause" (or "first principle") is something that is "simple", has infinite potentialities etc. — boundless
What the cosmological argument shows is that "infinite potentialities" (as infinite possibility) is physically impossible. Whatever has actual existence, at any given time, will limit the possibilities, such that "infinite possibility" implies that there is nothing actual. Because something actual is required to actualize any particular possibility, then if there ever was infinite possibility there would always be infinite possibility, and therefore nothing actual would exist ever. Since we observe that there is actual existence then it is impossible that there ever was infinite possibility.
"Many Worlds" has the means to avoid the cosmological argument (or is a manifestation of the disregard for it) by claiming that what we perceive as "the world" is just one of many possible worlds. But the fundamental problem with this is that we must adhere to this designation, and the logic of "possible worlds". And this means that we cannot declare any world as the "actual world". Each world is equally a possible world and there can be nothing to distinguish one world from another as the actual world. If we try to declare one world as the actual world, we step outside the boundaries of what is permitted by the logic. So we would have to refer to some other principle, something extra-worldly as that which distinguishes the actual world. Now we've just put ourselves back to Rene Descartes' position. What principle is going to ensure us, that the world we live in is "a real world"? So all we have is "my being", "my existence", "I am", to validate "my world". Therefore Many Worlds is inherently solipsistic because there are no principles whereby my world ought to be the same world as your world.
Anyway, Aristotle's argument is sound. — boundless
It's unusual that a scientifically minded individual would say that the cosmological argument is sound. It is generally framed in a theist/atheist argument where the scientifically minded person would take the atheist perspective. The problem is that the atheist is prone to denying the argument simply because it is used to support the theist position. Therefore instead of acting to properly understand the principles involved, and the force of the argument which is consequent upon understanding, the atheist will expend all sorts of energy attempting to dismiss the principles as unsound.
If it is true, then a "double-aspect" is heavily implied. — boundless
The "double-aspect" is a duality of "actual" existence. Forms of existence are describable states, which are assumed to have actual existence. This is the basis for logic, what is and is not. "Becoming" falls between the cracks of actual existence, so it is described as potential, the potential for this or that state of existence to follow what actually is right now. However, "becoming" is itself understood to be an activity, so this activity must be accounted for by something actual. Thus we have two distinct actualities, what actually "is", and what is active. Without employing this second actuality "becoming" appears to be infinite potential. Infinite potential is impossible, so we must, according to the cosmological argument assign a second type of actuality to account for activity itself.
In Aristotelian philosophy "form" refers to what is actual. We get a glimpse of this second type of form in his biology, as the soul. The primary definition of "soul" is as the actuality of a body having life potentially in it. This body is an active body, and the form here, the soul, is responsible for the activities (becoming) of the body. So in his biology, the describable states, forms of being are referred to as the potencies of the soul, and the soul itself is the principle of activity which is required to actualize the various potencies.
In this theory, free-will seems well explained. — boundless
Free will is well explained because it is taken as a premise, something concluded from observation, that human beings interfere in natural processes creating artificial things. Human activity is what necessitates the concept of "potential", that there is a multiplicity of possible states to follow any current state. And when we assume the reality of potential, what may or may not be, we need to allow exceptions to the fundamental laws of logic, referring to moral laws instead.
In your view the universe had a beginning? I agree that speaking about something "before time" is illogical ("before" is a temporal relation and outside time speaking of "before" or "after" is meaningless), but at the same time, to me it seems that this model requires that time had no "beginning" due to the fact that potentialities and actualities cannot be separated. — boundless
The point is not necessarily that the universe had a beginning, it's more like facing the fact that there are aspects of reality which are outside of our conception of time. So if "the universe" is restricted to temporal existence, (as we define time), then there are things outside the universe, things outside of time. If there are things outside of time, and temporal existence defines the universe, then it appears like the universe had a beginning. But in my mind, to say that there are things outside the universe is to speak contradiction, and so I conclude that our conception of time is faulty because it forces on us the contrary notion of something prior to time.
Imagine a point which is supposed to mark the beginning of time. At this point, there is only future and no past. In relation to temporal existence, this implies infinite possibility and nothing actual. There are numerous ways to demonstrate that this is a faulty principle. First, the notions of future and past are derived from the activity of time passing. At this point, there would be no time passing, as there is no past, and therefore to even use "future" and "past" in this context is invalid. Second, at this point, we need time to begin passing, so this is the "necessary cause" the "eternal actuality", which is external to the temporal universe and is implied by the cosmological argument.
But what the cosmological argument really does is demonstrate that our concept of time is inadequate for describing all of reality. There are parts of reality which are non-temporal according to our concept of time. But these parts have causal influence, so we can infer that they are in some way "temporal". Therefore we can conclude that our concept of time is in some way a misconception, and needs to be reconceived to bring these apparently "non-temporal" aspects into relation with the temporal.
This is not a new endeavour, it is what Plato grappled with in The Timaeus, and was taken up by the Neo-Platonists and earlier Christian theologians. Once we see the reality of that which is outside of time, we give it a name, the eternal. However, the eternal must have relations with the temporal or else we would not be able to see its existence. So the enterprising metaphysician is tasked with determining this relationship between the eternal and the temporal. My understanding is that our concept of time falls short, creating this separation between what is temporal and what is eternal. "Eternal", meaning outside of time, only refers to something real because our concept of time doesn't extend far enough to include those things which appear as being outside of time.
Just for curiosity: do you know online sources that explain well the cosmological argument of Aristotle? I am very curious to learn about his philosophy after this discussion :grin: — boundless
I haven't found a good presentation of Aristotle's cosmological argument online. it's very misunderstood and presented through various different lenses. The problem is that it's not well formulated by him in the first place, so it is left to others to pick and choose which statements to reproduce. The key aspects I find are in Bk.9 of his Metaphysics. A good, probably the best, re-formulation is that of Aquinas, in his Five Ways. I think it's Way #3. But even this is a re-presentation, from a Neo-Platonist, Christian perspective.
What Aristotle concludes is that anything eternal must be actual. He uses this to refute Platonic (Pythagorean) Idealism which assumes that human ideas, mathematics and geometry, are eternal. He shows that human ideas are "discovered", made actual, by the human mind, so if they exist prior to this they are of the nature of potential. He then proceeds to posit the idea of "unmoved mover" which is formulated as a perfectly circular motion. Because the perfect circle cannot have a beginning or an end (similar to the Hawking "no-boundary"), the circular motion is eternal. The Aristotelian proposal is defective though, so the Neo-Platonists just go on to assume eternal Forms which are actual. This produces a separation between human ideas which are potentials, and actual divine Forms, which are property of the divine mind, in Christian theology.
Aquinas has developed a quite complex concept of time. He introduces the concept of "aeviternal", which serves to differentiate between the two directions of time, looking backward, and proceeding forward. These two ought to be properly distinguished. Remember, the goal at that time was to produce a concept of time which related the eternal to the temporal. In the realm of the aeviternal are the angels, which are created at a point in time, as time has already passed, but live indefinitely into the future.
There is a way of ;looking at time implied here, which sees temporal existence as completely in the past. Instead of extending time equally to past and future, as we commonly do, we can say that only the past has real temporal existence, the future has not yet come to be temporally. The past is always being extended, all the time, and things come into existence at any moment of the present, and proceed with temporal extension. To account for things coming into existence, we look toward the future, they must come "out of the future". If, on the future side, there is a being like us, which always remains in the future (like we always remain at the present), never slipping into the past, then that being is always outside of time, eternal, always remaining ahead of the present, never coming into view at the present as it would if it slipped into the past. We have no way of understanding any activity of that being, because it is outside of what we know as time. It is eternal because it never slips past our view at the present, into the past. However the actions of that being could create things which slip into the past, come into view in our temporal existence.
Anyway, thank you very much for the interesting discussion we had so far :blush: ... and thanks in advance for the reply! — boundless
Well it's been a long process, we might take a break it up again on a later thread. You've been quite attentive to listen to some very unconventional ideas, demonstrating that you actually take the time to understand. I appreciate that. As you say, we are not at a position to produce any scientific theory but we may find a way in if we could carefully analyze and compare wave features. There are probably aspects of wave phenomena which are veiled by the Fourier uncertainty.
