Teleology (Aquinas 101)

Summary

This video explores the concept of teleology, the idea that everything has an end or purpose, drawing from Aristotle and St. Thomas Aquinas. It explains that understanding an object's purpose, like how a car is for transportation, is key to understanding its nature. Aquinas extends this idea to all things, including nature and inanimate objects, arguing that everything has a directedness or inclination toward an end. Ultimately, Aquinas asserts that this order comes from God, who is the source and ultimate end of all things, and that fulfilling one's purpose leads to flourishing.

Takeaways

• 🔍 Understanding something deeply involves asking, 'What is it for?' (its purpose).
• 📜 St. Thomas Aquinas, following Aristotle, discusses this concept as the 'end' or 'finality' of a thing, known as teleology.
• 🚗 Teleology is easy to see in artificial objects like cars (transportation) or clocks (keeping time).
• 🌍 Aquinas argues that teleology is universal—everything in existence acts towards an end or purpose.
• 👀 Even natural things have purposes: eyes are for seeing, and teeth are for chewing, with form and material suited to their function.
• 🌳 In both animate and inanimate nature, things have tendencies: trees grow toward sunlight, stones fall towards the earth, and matches generate heat.
• 🧠 These tendencies don't imply consciousness but show a reliable pattern of cause and effect, even in inanimate objects.
• 🔬 Science also presupposes this order by aiming to understand intelligible patterns within the universe, such as the Big Bang or evolution.
• 🙏 Aquinas concludes that this intelligible order points to an intelligent source, which he identifies as God.
• 👍 A thing reaches its fullest potential and flourishes when it attains its natural end or purpose—what is 'good' for it.

Q & A

What is teleology according to St. Thomas Aquinas and Aristotle?

Teleology, derived from the Greek word 'telos' meaning 'end,' refers to the idea that everything has a purpose or goal. Aquinas, following Aristotle, believes that understanding something requires knowing the purpose for which it exists.

How is teleology applied to artificial objects?

Teleology is easily applied to artificial objects by recognizing their purpose. For example, a car is made for transportation, and a clock is made to keep time. These objects are fully understood only when their purpose is clear.

How does Aquinas extend teleology to natural things?

Aquinas argues that teleology applies to all things, not just artificial objects. For instance, eyes are for seeing, teeth are for chewing, trees grow towards sunlight, and stones fall towards the earth's center. Everything acts for an end, according to its nature.

Why does Aquinas believe that even inanimate objects have a kind of directedness?

Aquinas believes that inanimate objects have a form of directedness because they follow reliable patterns. For example, a stone resists breaking, and a match generates heat. These behaviors indicate a natural tendency towards certain ends, even without conscious awareness.

How does modern science align with the concept of teleology?

Modern science, while not explicitly using teleology, presupposes an intelligible order in the universe. Science uncovers reliable patterns, systems, and rules in the natural world, which aligns with the idea that everything has a directedness or purpose, as Aquinas suggests.

What role does God play in Aquinas' understanding of teleology?

Aquinas argues that the order and directedness seen in all things ultimately come from an intelligent source, which he identifies as God. God is the ultimate end or purpose of all things, providing the foundation for their directedness.

How does the concept of teleology help us understand what is good for something?

Teleology helps define what is good for something by showing that things flourish when they achieve their natural end. For instance, eyes are good when they see, and teeth are good when they chew. This understanding helps explain the nature of flourishing and well-being.

Why is it considered bad to use things against their purpose, according to Aquinas?

Using things against their natural purpose leads to damage or harm. For example, using teeth to open a beer bottle can break them because they are not made for that. Things function best when used according to their intended end.

What is the connection between the reliable patterns in nature and Aquinas' teleology?

Aquinas sees the reliable patterns in nature, like a tree growing towards the sun or a match generating heat, as evidence of teleology. These patterns suggest that everything has an inherent directedness towards a specific end, revealing an underlying order in the universe.

How does teleology relate to human flourishing in Aquinas' philosophy?

In Aquinas' view, human flourishing occurs when people fulfill their natural purpose or end. This means acting in accordance with reason, pursuing the good, and aligning with the ultimate end, which is God. Teleology offers a framework for understanding human well-being and moral actions.

🔍 Understanding Teleology

The paragraph introduces the concept of teleology, drawing from St. Thomas Aquinas and Aristotle, which is the idea that everything has a purpose or end for which it exists. It explains that understanding the purpose of an object, like a car or a clock, is essential to fully comprehend it. Aquinas argues that this directedness towards an end is universal, applying to both living and non-living things. The paragraph uses examples such as eyes for seeing and teeth for chewing to illustrate this point. It also touches on Aquinas's belief that even inanimate objects exhibit a form of directedness, like a stone falling towards the Earth's center.

Keywords

💡Teleology

Teleology refers to the study of ends or purposes, derived from the Greek word 'telos' meaning 'an end.' In the video, it is described as the idea that everything has a purpose or is directed toward an end. For example, a car is for transportation, and a clock is for keeping time. The video uses teleology to discuss how understanding something’s purpose is crucial to understanding its nature.

💡Finality

Finality refers to the ultimate purpose or end for which something exists, similar to teleology. In the script, it is highlighted as a key concept in the philosophy of St. Thomas Aquinas, who, following Aristotle, believes that everything acts for an end. This concept is important to understanding how things are naturally directed towards achieving their specific goals or purposes.

💡Material cause

Material cause refers to what something is made of, an idea taken from Aristotle's four causes. The video explains this in the context of teeth being hard because they are made to chew food. The material cause helps explain why things have the properties they do, in alignment with their purpose or end.

💡Form

Form is another of Aristotle’s four causes and refers to the shape or structure of something that enables it to achieve its end. The video uses the example of teeth being shaped in a certain way to fulfill their purpose of chewing food. This concept of form is central to understanding how things are designed to fulfill their natural purposes.

💡Directedness

Directedness is the idea that all things, whether living or inanimate, are oriented toward a goal or end. The video explains this using examples like plants growing toward sunlight or stones falling toward the earth’s center. This concept underscores Aquinas’s view that everything in the universe acts according to a purpose, even if unconsciously.

💡Natural tendency

Natural tendency refers to the inherent inclination of things to move toward their natural end or goal. The video discusses this in terms of how eyes are naturally inclined to see and teeth to chew. According to Aquinas, recognizing these tendencies helps us understand what is good or bad for an object or being, such as how it is bad for eyes to be blinded because that prevents them from fulfilling their purpose.

💡Order

Order refers to the structured, intelligible arrangement of things, which Aquinas argues is present in the universe. The video states that even science seeks to uncover this order through patterns of cause and effect, like in the theories of the Big Bang or evolution. This order, Aquinas argues, ultimately points to an intelligent source, which he identifies as God.

💡Good

In the context of the video, 'good' refers to the fulfillment of something’s natural purpose or end. Aquinas believes that what is good for a thing is for it to achieve its purpose, such as how it is good for eyes to see. This concept ties into the broader theme of teleology, where fulfilling one’s purpose leads to flourishing.

💡Flourishing

Flourishing is the state of being in which a thing most perfectly achieves its end or purpose. The video describes how things are 'most perfectly what they are' when they are functioning according to their natural tendencies. Flourishing, in this sense, is about living in alignment with one’s purpose, whether it is a plant growing toward sunlight or a human living according to reason.

💡God

God, in Aquinas’s philosophy, is the ultimate intelligent source from which all order and purpose in the universe originate. The video concludes with the argument that the directedness and order seen in all things point to a higher intelligence, which Aquinas identifies as God. This serves as the foundation for his theological and philosophical system, where God is the ultimate end of all things.

Highlights

Understanding something deeply involves asking 'What is it for?' as per Aristotle and Aquinas.

Aquinas follows Aristotle's concept of teleology, where everything has an end or purpose, called 'telos' in Greek.

Artificial things like a car (for transportation) or a clock (for keeping time) have purposes that define their existence.

Aquinas argues that everything in nature acts for an end or purpose, whether it's living or inanimate.

Human anatomy reflects teleology: eyes are for seeing and teeth for chewing, and using them improperly can cause harm.

There is a 'directedness' in all things, even in inanimate objects like stones, which tend to fall toward the Earth's center.

Plants, like trees, show a natural tendency to grow toward sunlight, demonstrating an end-directed behavior.

Inanimate objects also have tendencies: a match, for instance, is directed toward generating heat.

Aquinas suggests this directedness does not imply consciousness; it's about reliable patterns inherent in things.

Even contemporary science presupposes an intelligible order in reality, finding patterns even in chaos or randomness.

Scientific theories like the Big Bang, evolution, and quantum physics reveal dynamic systems with ordered patterns.

Aquinas concludes that this intelligible order points to an intelligent source, which he identifies as God.

Aquinas believes that fulfilling a thing's purpose leads to its flourishing—eyes are best when they see, teeth when they chew.

Achieving the natural end of a thing also indicates what is good for it and what leads to its well-being.

Aquinas's philosophy shows that understanding purpose or telos provides insight into both the nature and the good of things.

Transcripts

If you're trying to understand something, one of the most important things to ask is,

what is it for?

St. Thomas Aquinas following Aristotle, speaks about this as the end or the finality of a

thing--that for the sake of which it exists.

This is sometimes given a more modern name, teleology, drawn from the Greek word for,

"an end," telos.

It's easiest in talking about this to start with artificial things.

A car is for the sake of transportation, a clock is made to keep time, and we cannot fully

understand these things unless we understand this end for which they exist.

Now, Aquinas would argue that teleology or being ordered to an end, that this is found

everywhere.

He thinks it's a universal truth that everything that acts, acts for an end.

This may be confusing to some people today and might even seem doubtful, but we quite

naturally think along this line.

For example, your eyes are made for seeing and your teeth are made for chewing food.

That's why teeth are made of such hard material.

That's their material cause and why they're shaped as they are.

That's their form, and this is why it's a bad idea to open a beer bottle with your teeth.

They're not made for that.

If you show up at your dentist office with broken teeth, he will probably tell you this

with a kind of strong moral disapproval.

Now, Aquinas thinks that there's a kind of directedness in all things, even in inanimate

things.

In the world of plants, a tree seeks to grow upwards towards the sunlight.

And in the world of inanimate things, a stone resists being broken apart.

While on earth, it has a tendency, a kind of directedness to fall towards the earth's

center.

A match has a directedness to generate heat.

St. Thomas in talking about things like this, does not mean that a match is conscious of

a desire to generate heat.

The match isn't thinking about anything.

Aquinas is thinking of the reliable pattern that things like matches insofar as they are

matches, do precisely this--

they generate heat.

Even contemporary science in a certain way presupposes this.

Science aims to understand reality, which means discovering whatever is intelligible in it.

Even where we might at first think we see chaos or randomness, science is often able

to show us that there is in fact within it a dynamic system with ordered rules and systematic patterns.

In other words, there is an intelligible order that our minds discover already existing in

the universe and we detect it wherever there is a reliable pattern of cause and effect

as in the theories of the Big Bang or evolution or in quantum physics.

St. Thomas argues that this order ultimately must come from an intelligent source, which

he calls God, who is the ultimate end of all things.

There's one further and important conclusion to draw from this.

If things have a natural tendency or inclination, if as the kind of things they are, they're

directed towards something, then they will be most perfectly what they are when they

are most perfectly doing what they're directed at doing.

It's bad for your eyes to be blinded.

It's good for them to see.

Attaining to the end or the goal is thus, more than just a description about your eyes.

It also tells us something crucial about what is good for a thing and what leads to its

flourishing.
