    Saying that someone "should know" is an infinite regress, because obviously they don't know that they should know. Your examples also assume that the bad-actor (de Medici) knows that usury is wrong.

    Around 12:30, how does the will fail to consider something? I thought the will selects what the intellect presents to it as the best good. The will doesn't have contemplative properties, does it? Only the intellect can contemplate. Thoughts?

    Can you prove that whatever is unmoved mover is omnipotent, omniscient, omnibenevolent, unique, simple, and perfect?

    • @ElliotPolskyPhilosophy
      @ElliotPolskyPhilosophy Місяць тому

      Not demonstratively from natural reason. You can get part of the way there, however. You can show that the unmoved mover is simple with regard to quantitative and essential parts (i.e., doesn't have body parts or matter-form composition). You can also show that the unmoved mover is perfect in itself, though I'm not sure you can show it is infinitely perfect in the way Christianity claims. Aquinas explicitly says omnipotency is an article of faith, not something proved through natural reason.

    Your videos are by far the best by virtue of precision that gives rise to clarity. I have watched just about everything on UA-cam/Spotify in the realm of thomism (1000s of hours) and your videos have helped me more than all of the videos/podcasts combined. I was wondering if you could possibly do a future video on this topic… - 7 deadly sins and their daughters / virtues that correspond to them - Gifts and fruits of Holy Spirit - 64 virtues and consequent vices (Fr. Ripperger has a list) I read almost entirely 3 authors and those are St. Thomas Aquinas, Aristotle and Fr Ripperger. If you haven’t already give this book a read. - Introduction into the science of mental health -Fr Ripperger I am interested in this topic above as this would help in a more concrete and practical manner with many individuals… especially those who are idiots when it comes to philosophy/theology truth and putting that truth into the concrete (I’m one of those idiots lol). Here’s an example, let’s say I struggle with x vice and I have x daughters. The corresponding virtue to that vice/daughter would be x. Thank you for all your work you have done! Always remember to follow the truth no matter the personal consequences! God bless!

    I don't understand how "white" is a property of swans. Isn't "not found outside the species" part of the definition of property"? There's plenty of white species.

  • @TruthNerds
    @TruthNerds 5 місяців тому

    The conversion of a universal affirmative ("Every swan is white") is a particular affirmative ("Something white is a swan")? I'm not willing to accept that because the latter requires swans to exist (at least if something white exists) but the original statement does or should not. Now, of course, we know that swans and white things exist, but the entire point of the exercise is to look at the structure only, so we should be able to say, neutrally, "Everything A is B" and the alleged conversion "Something B is A". Also, we can essentially define that "every A is B" shall imply that at least one A exists. But I don't think that's a good idea for the following reasons: FIrst, the conventions I personally know, e.g. in programming (all function in Haskell, std::all_of in C++) or first-order logic (∀x: A(x) → B(x) is true if there is no x such that A(x)) Second, in mathematics, it is quite useful to construct statements of the form "Every _something that doesn't exist_ is …" for the purpose of proof by contradiction. Third, and I admit that's rather technical, if we don't consider "Every A is B" to imply the existence of an A, and we need that, though, we can easily add an axiom to our axiomatic system that says "There is an A". However, if we do consider that "Every A is B" implies this and we do not want this additional axiom, we need to remove it with an implication: "If there is an A, then every A is B." and an implication translates to a disjunction ("There exists no A or every A is B."), which can't be a separate axiom because axioms are effectively combined in a conjunction (logical and). (Maybe I'm missing something, of course…)

    • @TruthNerds
      @TruthNerds 3 місяці тому

      To answer my own objection … Aristotelian logic differs in this from Boolean logic. I.e. in modern times, we do not consider a universal affirmative to imply the existence of the subject but Aristotle did. Conversions from one system to the other need to take this into account.

    This is another fantastic lecture and it has been very useful in helping to reinforce my learnings from Jensen's books on sin and natural law. Do you have any thoughts as to how to avoid an infinite regress of interactions between the intellect and will when considering sin as culpable ignorance? For instance, the final step appears to fall with the will in allowing substitution for a major premise (sins of weakness), a minor premise (sins of ignorance), or an entire syllogism (sins of malice). However, how can we avoid saying that the intellect could subsequently inform the will that avoiding this substitution would be a higher good? We might answer that the will has ceased this process, but one might object that the intellect could inform the will that avoiding cessation would be a higher good? This would lead to an infinite regress. Do we merely say the will's cessation of the process is an irreducible fact? I believe this culpable ignorance is understood as "choosing without a rule." However, I've really struggled with understanding 1.) how one can be culpable without ending the process with the intellect's information and 2.) how one can be free without ending the process with the will's choice. How do we reconcile this to allow for culpable freedom?

    • @ElliotPolskyPhilosophy
      @ElliotPolskyPhilosophy 5 місяців тому

      Unfortunately, there is no settled or even standard solution to the infinite regress I know of. A not terribly satisfying solution is the one Aquinas seems to offer with a citation to the Eudemian Ethics. Ultimately, a higher agent (i.e., God) causes the first movement of the will, which starts the whole immanent process of interactions between intellect and will. In a context like this, it is probably best to stop at this general solution without trying to spell it out in detail. On the question of whether God would then be culpable for the sins that result from his not causing morally right acts of will in humans, the basic answer is that, since everything God does with regard to creatures is gratuitous and a good unnecessary for his own perfection achieved in himself, whereas everything positive in human action is attributed to God, every defect is attributed only to the human to whom it is proper to act, not to God, who doesn't need to give any good to creatures to achieve his own good. I should again emphasize that all this is very much a basic sketch, and there are many problems that would have to be addressed.

    This is another outstanding presentation. I am enjoying all of your work. One question here: Do you feel the estimative power is involved in the training of the sense appetites? E.g., Are both being trained in concert? What do you feel is the relationship between these two powers in the acquisition of virtue?

    • @johannesgh90
      @johannesgh90 6 місяців тому

      Good question, and I'd also like to know, but I think you mean i.e. - id est means "that is", or literally it stands for "it is", while e.g. stands for exempli gratia, which means "for example" - I can never remember acronyms without knowing what they stand for so here you go.

    @kellywilbur 7 місяців тому

    These are excellent lectures! I'm so glad I found them. I do have one question. At 30:02 you said, "the will cannot cause the body to do anything directly." Is there a way to align this with ST I Q82 a4: "Secondly, a thing is said to move as an agent, as what alters moves what is altered, and what impels moves what is impelled. In this way the will moves the intellect and all the powers of the soul" and "Therefore the will as agent moves all the powers of the soul to their respective acts, except the natural powers of the vegetative part, which are not subject to our will." Thank you!

    • @ElliotPolskyPhilosophy
      @ElliotPolskyPhilosophy 7 місяців тому

      Thank you for the feedback! The quotations you give do not describe the will moving the body , only it moving the body. So, there is no contradiction between them and Aquinas's claim that it does not move the body directly, but by way of the sense appetites and imagination.

This information is sprinkled about, but I have yet to see a clear and concise run through of "Johnny and the piece of pizza" with a walk through of what exactly each power of the soul is doing in a given activity (i.e., how the intellect and will interfaces with the external senses, internal senses, sensitive appetite and locomotive powers). Please let me know if you are aware of any relevant publications. Thanks!

    Question: How does prime matter relate to the material cause? Aristotle uses the example of bronze being the material cause of the statue, but that seems like it is a per accidens material cause since "bronze" is not a requirement of making a statue a statue (unless of course if we were talking about a bronze statue rather than just a "statue"). Love your videos by the way.

    • @slocole1005
      @slocole1005 19 днів тому

    What kind of being would color be, considering that light or electromagnetic radiation is not color neither contains color, it contains rather different wavelengths, frequencies, amplitudes of the electric and magnetic field in a spacial direction in time, so those would be the accidents of the substance "light", then in the human person who sees you have a sensitive power that receives and unifies those accidents through the eye, retina, cones, and all of that to bring about the perception of "color", which is also called "visible" light which means that it's a light that has to be perceived by vision in order to be such, plus you have the mediums in which light is carried and reflected on which are not color neither contain the accident of color within them, color occurs only when all of those things are in relationship with each other so color isn't a being in its own right but rather it is due to accidental relations within very specific substances in a very specific manner.

    At 1:23, Occult means hidden. There’s nothing superstitious about. And metaphysics fall under Occult Science, because metaphysical things are not apparent, which means that it can’t be a science. In order for something to be scientific, you have to be able to empirically measure something.

  • @AprendeMovimiento
    @AprendeMovimiento 9 місяців тому

    I am having a trouble with the notion of "Color" because there is no color in the skin (using your example) neither color in the sight or the eye, neither color on the light or electromagnetic radiation, you get what we call "color" only when there is accidents in relation to each other, the power of sight + electromagnetic radiation (light) + and a medium through which the light travels and/or is reflected on (the skin for example). Color is also called "visible light" because for color to be a thing it needs the person with sight sensing electromagnetic radiation at a specific frequency as such and such "color". So color is not an actual thing in that or that substance but only exists through an accidental relation of sense power, the accidents of light and of the medium for light. Help me please ❤

This is an issue I have been wrestling with for many months. This most clear and brilliant presentation was literally an Answer to my Prayers. I have now watched it 5 times in the last 24 hours, and the presentation is so well done and so enjoyable and interesting, every time I have listened to it my notes have picked up on more issues which inspire even more questions. I can not thank you enough for the very great inspiration, brilliance and thought and care that has been put into this presentation. It is so beautifully done, I have even shared it with a Loved One who is was not deeply interested in the subject matter . . . . . . until now ! Peace be with you and may GOD Bless you abundantly.

    🎯 Key Takeaways for quick navigation: 00:02 🧠 Thomas Aquinas defines three operations of intellect: simple apprehension, judgment, and knowledge by reasoning. 01:34 🧩 Syllogism components: premises (self-evident) and conclusion (non-self-evident). Terms are words/phrases within propositions. 03:03 💡 Self-evident propositions: predicate in subject's definition, subject in predicate's definition, or subject causes predicate. 04:13 ❌ Non-self-evident propositions: contingently true or dependent on prior self-evident propositions. 07:20 📊 Proving non-self-evident propositions: derive from self-evident premises, using logic and reasoning. 09:16 🎓 Understanding, science, and wisdom are intellectual virtues. Opinion, error, and fallacy are non-virtuous habits. 11:17 🤖 Science is an intellectual virtue that leads to knowledge through reasoning from self-evident principles. 14:12 🔬 Three types of science: Natural Philosophy (physics), Mathematics, and Metaphysics. 17:24 🌍 Distinguishing sciences by their object's separation from matter and motion. Individual matter, common matter, sensible matter, intelligible matter. 24:07 👼 Metaphysics studies being in general, separate from all matter. Positively immaterial (e.g., God) and neutrally immaterial (e.g., substance). 25:35 🔍 Sciences judge conclusions differently: natural philosophy uses external senses, mathematics uses imagination, metaphysics uses reason. 26:46 🌐 Mixed sciences combine principles from one science (e.g., math) to study objects of another science (e.g., biology). 27:30 🧠 Philosophy of the human person studies the soul as immaterial substance, differing from psychology's mixed science. 28:02 🔍 Metaphysics has four names: Metaphysics (after physics), Divine Science or Theology (study of God), First Philosophy (first causes), and Wisdom (first principles). 29:26 💭 Metaphysics consists of Critique (study of human knowledge), Ontology (principles of being), Usiology (study of sensible substances), and Natural Theology (study of immaterial substances). 30:26 📘 Logic is a liberal art and speculative science; studies spoken words to produce habits of clear and orderly thinking. 30:54 🔍 Logic studies beings as conceived by the mind, while metaphysics studies beings as they are in themselves outside the mind. 31:25 🕊️ Metaphysics (natural theology) studies God as a principle of sensible things; sacred theology (revealed theology) studies God based on revelation.

    Here is an attempt to symbolize some of the key problems with each of Aquinas' Five Ways using symbolic logic: First Way (Motion) 1. Everything that is moved is moved by another (premise) 1. There cannot be an infinite regress of movers (premise) 1. ∴ There must be an unmoved mover (from 1 and 2) Problem: 4\. ◇∃x(~Mx & ~∃yMyx) It is possible that there exists some x that is unmoved and yet there is no y that moves x In other words, premise 2 is questionable because it is possible for there to be an infinite regress of moved movers, without any unmoved mover. Second Way (Causation) 1. Everything that is caused is caused by another (premise) 1. There cannot be an infinite regress of causes (premise) 1. ∴ There must be an uncaused cause (from 1 and 2) Problem: 4. ◇∃x(~Cx & ~∃yCxy) It is possible that there exists some x that is uncaused and yet there is no y that causes x As with the First Way, premise 2 is doubtful because an infinite causal regress is possible. Third Way (Contingency) 1. Contingent beings exist (premise) 1. Contingent beings require a necessary being (premise) 1. ∴ A necessary being exists (from 1 and 2) Problem: 4. ~□∃xNx It is not necessary that a necessary being exists The move from contingent beings to a necessary being is invalid. The existence of contingency does not necessitate the existence of necessity. Fourth Way (Gradation) 1. Finite goods exist (premise) 1. Finite goods require a maximum good (premise) 1. ∴ An absolute maximum good exists (from 1 and 2) Problem: 4. ~□∃x(Mx & ∀y(My → x≥y)) It is not necessary that there exists some x that is maximally good such that x is greater than or equal to any other good y. An infinite regress of greater and greater finite goods is possible, without any absolute maximum good. Fifth Way (Teleology) 1. Non-intelligent things act towards ends (premise) 1. Non-intelligent things require an intelligent director (premise) 1. ∴ There exists an intelligent director of things (from 1 and 2) Problem: 4. ~□∃xDx It is not necessary that there exists some intelligent director x of things. The move from the apparent functionality of nature to a cosmic intelligent designer is invalid, since there may be naturalistic explanations for biological teleology.

      An infinite regress of the type Aquinas is speaking of is logically impossible. It follows from premisses 1 and 2. Such a series would result in no movement, not movement.

  • @Enigmatic_philosopher
    @Enigmatic_philosopher 11 місяців тому

    Here is a comprehensive philosophical critique of the arguments for God's existence in Summa Theologica: First Way (Motion) - The argument relies on an outdated Aristotelian physics that viewed motion as a transition from potentiality to actuality. Modern physics rejects this framework. Motion can occur without external causes. - Even if we grant the principle that whatever is moved is moved by another, it does not logically follow that there must be an unmoved mover. There could be an infinite regress of moved movers, each moved by a prior cause. Aquinas gives no justification for rejecting such a series. - The argument illicitly moves from observable motions to an unobservable first mover. We have no empirical evidence of a first uncaused cause of motion. It is a metaphysical assumption. - The argument assumes that the first mover must be God. But even if we grant an unmoved mover, it need not have all the properties of God such as perfection, goodness, infinity etc. Second Way (Causation) - As with the first way, the argument relies on an outdated Aristotelian view of causation that is no longer accepted in modern science. Causes do not have to temporally precede effects. - There are credible modern cosmological theories, like eternal inflation, that posit infinite causal regresses. Aquinas gives no good reason to reject such theories out of hand. - The argument illicitly moves from observable chains of causation to an unobservable first cause. We have no empirical evidence of a first uncaused cause. It is a metaphysical assumption. - Even granting a first cause, it need not have the properties of God. It could simply be an impersonal necessary being. Third Way (Contingency) - The argument relies on an Aristotelian cosmology of necessity and contingency that does not match our modern understanding of the universe. - The argument illicitly moves from the existence of contingent beings to a necessary being. We have no empirical evidence of any non-contingent entities. It is a metaphysical assumption. - The argument equivocates between ontological necessity and causal necessity. Something may be necessary causally but still contingent ontologically. - Even granting a necessary being, it need not be God. It could simply be an impersonal ground of being. Fourth Way (Gradation) - The argument relies on an Aristotelian metaphysics of degrees of perfection that is questionable. There are other explanations for degrees besides exemplar causality. - The move from finite goods to an infinite good is invalid. Infinite regresses are possible, so no maximum is necessarily implied. - The maximum being inferred need not be God. It could simply be an impersonal absolute. The properties of goodness, knowledge, power are assumed rather than proven. Fifth Way (Teleology) - The argument relies on empirically questionable teleological explanations in biology. Most adaptation is explained by natural selection, not intentional design. - Even granting the analogy of design, at most this proves a designer, not necessarily God. We have no warrant to assign properties like perfection, infinity or creativity to the designer. - The argument illicitly moves from particular cases of apparent design in nature to a cosmic designer. Local adaptation does not imply cosmic teleology. In summary, Aquinas' five ways are based on Aristotelian metaphysics, science and logic that is outdated and empirically dubious. They rely on illicit moves from the observable world to unobservable metaphysical assumptions. And even granting their dubious premises, they do not lead specifically to the God of classical theism. At best, they point to an impersonal first cause, necessary being, maximum goodness or intelligent designer. Aquinas' arguments are ingenious products of their time, but they do not provide compelling reasons to believe in God from the perspective of modern philosophy and science.

      Well written but I disagree that the dialectic regarding the 5 ways has been resolved-which seems to be what you are claiming. The interpretations of the 1st way I’ve heard read motion as the actualization of potential. Here it’s argued that even the continued existence of an x from time t to time t+1 is a change reflecting the continuous underlying dependence of x on forces outside of x itself to bring x from t to t+1. Regarding the 2nd way & causation, there are numerous “grim reaper” type contradictions when you assume an infinite causal series for a finite effect. Regarding contingency arguments, many would argue if you accept the PSR you’ll need a necessary foundation if you want to avoid brute facts. As to your claim this foundation doesn’t need to be God, well the divine attributes follow from an analysis of the characteristics of such a foundation. But I’d like to set that aside. By my lights, Rejecting the PSR puts both science & reason on shaky ground. The fourth way has been interpreted as way of presenting the de Ente argument and is about actuality. That existence is held in a per se causal series. So just as the fire transfers heat to objects that don’t retain heat in themselves so too does God grant acts of existence to beings who don’t have it in their nature to bring about or explain their own existence. The 5th way interpretation I’m most familiar with has to with innate teleology, not exterior imposed teleology. The whole idea of the law like behavior of the natural world supports this view. That down to whatever scientific level you want to go: chemical, biological, physical, you see predictability (not necessarily determinism) & pattern, Not absolute & utter randomness. sub atomic particles, atoms, molecules, cells, biological parts, whole living things, and non living material exhibit their natures, powers, & characteristics in predictable ways-flowing from the type of substance they are. When you strike a match a flame is created not lilacs. That’s teleology. (Fine tuning arguments are also used to support a more exterior teleological argument. ) And to make a blatant appeal to authority id recommend the works of Pruss, Kerr, koons , and others. I’m sure my presentation of these interpretations of the 5 ways has flaws, but to act like there’s still not an ongoing dialectic here is inaccurate by my lights. Cheers

      The rejection of an infinite regress is a logical coclusion from premisse 1 and 2. It can not happen.

    I didn`t quite grasp how is ad unum different from ab uno. It seems like in the examples ad unum exploited both types of causality and ab uno exploited the final one, contrary to the description.

    2:35 i think a more appropriate way of converting those sentences with implicit copulas into senteces with explicit copulas is "Socrates is such that he sits" or "Squirrels are such that they eat". i think that because the terms "eat" and "eating" have slightly different meaning and i think it would be prefereable to preserve the meaning of each term of the sentence.

    • @ElliotPolskyPhilosophy

      Yes, there are slightly different nuances in English between "runs" and "is running"-for instance, "is running" sometimes implies "is running habitually" instead of "is running actually"-but we can stipulate these away. Grammatically, there is nothing that prevents them from meaning the same thing. To say that these phrases-or any two phrases-are exactly the same in the custom of everyday language is impossible. With that said, all Medieval authors see "est currens" and "currit" as logically equivalent. That is what I am referring to though it needs some qualification. On the other hand, "Socrates is such that he runs" (Socrates est ut currit) is not equivalent since it is no longer a simple proposition, but a composite one with a result clause (ut ... = such that ...). Moreover, in the first clause prior to the result clause has "est" ("is") as the principal predicate, not a third thing added (tertium adiacens). As a result, the proposition has a very different logical form from "Socrates is running" or "Socrates runs."

    How do I answer the question "what is philosophy"? It's not enough to answer "a theoratical activity"( as there are probably many other forms of theoratical activities). I know it from the account of St. Thomas in the Ethics as: oder that reason does not establish but beholds( natural philosophy). But it seems we'd have to introduce the historical aspect to set philosophy off from other forms of theoratical activity that arose in other parts of the world( for eg. in India). Anyway, how would you define "philosophy". And are there works on this? ( Btw you should post something on community post, that way the comment section will not get cluttered)

    There are, I think, several problems with this. First, sins of malice appear to be sins of ignorance with respect to higher moral values. So, the difference between the two categories is unclear. But this projects a problem for the entire analysis of the issue, since the problem is that some people know the good and pursue the bad. Such a situation would not have existed if only ignorance, in some form or another, was at play. This is why Ayn Rand's analysis is better: it introduces the mechanism of evasion by which ignorance is deliberately created so as to do evil. And that grounds moral judgment, because evasion is the result of volition. Also, some of the examples are weird. Oedipus, to name one, can't have committed a sin precisely because of his ignorance. Ignorance of that kind is exempting of moral condemnation.

      Presocratic Fragments (published by Hackett) is easy cheap option. Best option, however, is just to start by reading Aristotle's Physics I and Metaphysics I-IV for summaries of the presocratics. Most of what we know of them is from Aristotle.
