Thomas Aquinas’ argument from degree for the existence of God can be summarized as follows:
P1: If there exist beings with varying degrees of a property, then there must exist a being with that property to the maximum degree.
P2: There exist beings with varying degrees of moral goodness.
C: The moral good to the maximum degree exists (which is what we call God). — Samuel Lacrampe
Eg 1: Take a circle: A hand-drawn circle is called a good circle if it gets close to a perfect circle, its nature, and called a bad circle if it gets far from it. — Samuel Lacrampe
This argument is reminiscent of the Ontological Argument isn't it? — gurugeorge
It is different in that the Ontological Argument aims to prove the existence of Perfection (a being perfect in every way) based on the essence of Perfection (which fails because we have not apprehended the essence of Perfection). It starts with the essence of Perfection and ends with its existence.This argument reminds me of the ontological arguments of Anselm and Descartes. — darthbarracuda
You are correct, when it comes to the aim of persuasion rather than to seek truth. This is why I used the terms nature and function rather than formal and final causes (only added in one line for the fans of Aristotle); but there is always room for more clarity.The only problem with this line of reasoning is [...] with the fact that the "technical" metaphysical concepts involved [...] are quite alien to thinkers raised on "modern" and "Postmodern" philosophy and require extensive explication — gurugeorge
Maybe I misunderstand your point here; because as I understand it, that is also my point in the argument; that the potential of moral goodness in persons is the potential to achieve moral perfection.The added wrinkle is that objective morality, in the Aristotelian/Thomist system, is itself related to degrees of perfection (the moral person seeks to actualize their potential, the form of them, as best they can). — gurugeorge
That's a valid point. Slight correction: The existence of imperfection does entail the existence of perfection, though sometimes only from our minds rather than from reality outside the mind. I accept the possibility that perfect circles are man-made (I am not certain about this but this would be off-topic). Now a man-made being entails that we know its essence. E.g., we must conceive the essence of a hammer before we build one.My objection to P1 can be illustrated by objecting to this part of your argument. There are no perfect circles in the world. Every circle is slightly elliptical, they never have a perfectly uniform radius. The point being is that the existence of imperfection does not entail that perfection must exist. — darthbarracuda
In the case of moral goodness, we have not fully apprehended the essence of perfect morality, and therefore this being cannot be man-made. Instead, we deduce its existence from the existence of imperfect moral goodness. — Samuel Lacrampe
I agree with your representation of the argument. This is essentially what I was attempting to describe too, though it may not have come out that way.I don't think the argument from gradation is properly represented here, P1 seems a little simplistic. [...] — Metaphysician Undercover
I think you are on to something when making the distinction between qualities and quantities, and I also agree that when it comes to quantities, there cannot be an ideal because there is no maximum. However, it is not necessary to prove that qualities cannot be reduced to quantities. What is necessary is to prove the existence of the ideal for goodness. Your way is indeed a means to that end, but not the only one. I use a different approach in the OP by showing that the judgement of goodness is possible only if an ideal exists.The argument may not be sound though because in the case of quantities, the ideal is "infinite". So with quantities the ideal escapes the maximum. What is required to make the argument sound, is to establish an acceptable distinction, a categorical division, between quality and quantity, such that a quality cannot be reduced to a quantity. If qualities are really quantities, then the ideal is infinite, there is no maximum, and the argument is unsound. — Metaphysician Undercover
If perfect moral goodness could not or did not exist, then it would not be possible to rightly judge a being to be morally good; because, as described in the OP, a being is called good insofar as it gets close to its perfect nature.How do we do this? Could it be that perfect moral goodness cannot exist? — darthbarracuda

Interesting. I am not familiar with this notion of "fundamental unit". Can you give examples to illustrate that the unit must be real in order to have a quantity?Judgement for quantity requires the assumption of a fundamental unit, or unity, as a particular, an individual. So the soundness of this judgement, the judgement of quantity, is based in the reality of the assumed unit. The assumed unit allows for a first, the one, then the other numbers of the quantity may follow. [...] That the ideal must be real can only be known intuitively and cannot be proven with logic, but that the unit, the individual or particular must be real, in order that there is a quantity, can be proven with logic. — Metaphysician Undercover
But we know it is the case for goodness, straight from the definition of goodness: the measure of how close a being gets to its perfect nature or ideal. Under such a definition, an ideal must exist for the judgement of goodness to apply. This definition is backed up by the examples given in the OP. Do you disagree with it?it is based in the assumption that to judge for goodness requires the existence of the ideal (maximum) for goodness. I don't think that this assumption is sound because we can judge for quantity without the ideal (maximum) for quantity. — Metaphysician Undercover
What he means about maximum is not a maximum absolute quantity but a maximum in actuality from potentiality; or to say the same thing in a different way, a grade of 100%, which can be seen as a relative quantity, relative to the perfect nature or ideal.But notice that the reality of the ideal is not necessarily based in a maximum, as Aquinas describes. The reality of the ideal is the grounding principles for the system of gradation. When Aquinas talks about a "maximum" for goodness, this implies the character of a quantity, and this gives the argument an unsound premise to begin with. — Metaphysician Undercover
The only problem with this line of reasoning isn't with the reasoning itself, which is lucid, rather with the fact that the "technical" metaphysical concepts involved (like actuality and potentiality, formal cause, final cause, increments towards perfection, etc.) are quite alien to thinkers raised on "modern" and "Postmodern" philosophy and require extensive explication — gurugeorge

The "existence" is based on scholastic realism's belief in the extra-mental existence of universals. Once that is made explicit, the significance of the "proof" as a proof evaporates. It remains, however, as an artifact of a certain kind of thinking. The presentation of the "proof" as a proof without making its realist underpinnings clear (if known - a material qualification), is simply fraud. — tim wood
I see. Real quantities imply real units. Although real, some can be man-made or arbitrary, such as 1 m in length, 1 kg in weight, etc. Anyways, I suggest dropping this side topic to focus on the main one.A "quantity" is always a number of units. If the units are not real, then neither is the quantity. If you have a quantity which consists of unreal, or false units, then this is not a real quantity. — Metaphysician Undercover
Of course it supports my position, but it is not done arbitrarily for that aim; rather, the definition comes from the Socratic Method using the examples in the OP. To refute it, we would have to find an example that does not fit the definition. And you have attempted to do that with the example on human purpose. See below for the response on this.You are defining "goodness" in a way so as to support your position. — Metaphysician Undercover
And what unit of measure would the utilitarian use? Note that the definition is for goodness in general, and not merely for moral goodness.But if you define it in a utilitarian way, you judge goodness by a quantity — Metaphysician Undercover
Yes, that follows.So if we follow your definition, we would have to assume that there is a purpose for human beings, in order that a human being could be judged as good. — Metaphysician Undercover
A valid point. And now let me blow your mind :cheer: .In order to judge the goodness of any human being, or any human act, we'd need to know this purpose of human existence, and position the person, or act, relative to it. But clearly we do not know this purpose, and we do not judge goodness in this way. — Metaphysician Undercover
I suspect a misunderstanding either from me or from you; because as I understand your comments, I have already addressed these objections in my previous post. I'll try again, and maybe you can clarify. A maximum cannot imply an absolute quantity because absolute quantities are theoretically infinite, and so no maximum is theoretically possible. It can only imply a relative quantity, a percentage, where the maximum is 100%. I suppose you could also call it a quality insofar that relative quantities don't have any units. But as a relative quantity, I see not contradiction."Maximum" is a term which applies to things which are measurable, as is "quantity". To say that there is a "maximum" is to say that there is a "quantity", and this is to say that the thing is measurable. But you define "goodness" as a quality. So by talking about a maximum goodness you talk about goodness as a quantity, when you have defined it as a quality. — Metaphysician Undercover
Through inductive reasoning, we can find the human purpose based on what we observe to be a good human being: — Samuel Lacrampe

The ‘is–ought problem’, as articulated by the Scottish philosopher and historian David Hume (1711–76), which states that many writers make claims about what ought to be, based on statements about what is. Hume found that there seems to be a significant difference between positive statements (about what is) and prescriptive or normative statements (about what ought to be), and that it is not obvious how one can coherently move from descriptive statements to prescriptive ones. The is–ought problem is also known as Hume's law, or Hume's guillotine. — Wikipedia
A "quantity" is always a number of units. — Metaphysician Undercover
thus in Aquinas's terms, we might conclude that there may be many Gods. — Pilgrim
