Aristotle’s Definition of Time in Physics IV: Aristotle on Time

Aristotle on Time

Diving into Aristotle’s thoughts on time in Physics IV feels like unraveling the mysteries of time itself.

It’s not just a philosophical musing but a deep dive into the fundamental questions that have puzzled thinkers for centuries.

In this section of his work, Aristotle grapples with some of the most perplexing aspects of time, and his insights are as relevant today as they were over 2,000 years ago.

Aristotle’s Puzzles About Time: Aristotle on Time

Aristotle starts his discussion by laying out the difficulties and puzzles surrounding the concept of time.

In The Physics, he presents “a statement of the difficulties about the attributes of time.”

These are the hard questions that have stumped philosophers and scientists alike:

  • What is the nature of time?
  • Does time exist independently of change and motion?
  • Is time continuous or composed of indivisible instants?

Aristotle dives right in, facing these challenges head-on without hesitation, determined to untangle the mysteries of time.

One of the key insights Aristotle offers is the intricate relationship between time and change.

He argues that while time is not identical to change, it is inextricably linked to it. In his words, “time is not a kind of change, but that it is something dependent on change.”

This is a crucial distinction. Time isn’t just another form of change or motion, but it can’t exist independently of it either.

It’s a unique attribute that emerges from the reality of change in the physical world.

Defining Time as a Number of Change

So, how exactly does Aristotle define time?

In a stroke of philosophical genius, he describes it as a kind of “number of changes” concerning the before and after.

This dense formulation packs a lot of meaning. As Coope explains, time is a type of order, a way of arranging and relating all the various changes unfolding in the universe.

By counting time instances, we’re effectively marking out the “before and after” of change, putting all events into a unified sequence.

This definition is a far cry from our everyday notions of time as an absolute, independent flow.

For Aristotle, time is deeply interwoven with the reality of change, a unique expression of the dynamic nature of the physical world.

He makes us question what we thought we knew, pushing us to really consider how closely time and change are linked.

Key Takeaway: Aristotle on Time

Aristotle sees time as a “number of change,” linking it closely to motion and change rather than an independent flow. This view forces us to rethink our understanding of time’s true nature.

The Dependence of Time on Change in Aristotle’s View: Aristotle on Time

Aristotle’s theory of time is a head-scratcher, to say the least.

He claims that time depends on change, but what does that mean?

Let’s unpack this idea and see where it takes us.

Arguments for Time’s Dependence on Change

Aristotle’s main argument for time’s dependence on change goes something like this:

Time is a kind of order that relates all changes to each other. It’s a universal framework in which every change finds its place.

But here’s the kicker – Aristotle thinks that without change, there would be no time. Time only exists because things are constantly shifting and transforming.

As Ursula Coope puts it in her book Time for Aristotle, “Aristotle claims that time is not a kind of change, but that it is something dependent on change.”

In Aristotle’s view, time is a parasitic entity that latches onto change. It can’t exist on its own.

This is a pretty radical claim, raising all sorts of questions. If time depends on change, does that mean time itself is constantly changing? How do we make sense of that?

Aristotle’s theory challenges our common-sense notions of time as fixed and absolute. It suggests that time is more fluid and relative than we might think.

Objections to Time’s Dependence on Change: Aristotle on Time

Of course, not everyone buys Aristotle’s argument about time’s dependence on change.

Some philosophers have raised objections, pointing out potential problems and inconsistencies in his view.

One issue is that Aristotle seems to contradict himself at times. On one hand, he says that time depends on change. But on the other hand, he also claims that change depends on time – you can’t have change without time passing.

So which is it? Does time depend on change, or does change depend on time? Aristotle’s theory appears to go in circles.

Another objection is that Aristotle’s view seems to imply that time is subjective and mind-dependent. If time only exists when a soul or mind perceives change, does that mean time is just a figment of our imagination?

This is troubling for those who believe in the objective reality of time. We like to think that time marches on whether anyone can experience it.

As Coope notes, “On the interpretation favored by Coope, however, Aristotle could have assumed that change depends on time since he believes that there is no change without time. The fact that he does not assume this calls for an explanation.”

These are just a few difficulties connected with Aristotle’s theory of time’s dependence on change. This view raises as many questions as it answers.

Implications of Time’s Dependence on Change

Despite the objections and puzzles it raises, Aristotle’s theory of time’s dependence on change has some intriguing implications.

For one thing, it suggests that our experience of time is intimately bound up with the changing world around us. We don’t perceive time in a vacuum but through change and motion.

This could help explain why time seems to speed up or slow down depending on what we’re doing and how engaged we are. When we’re absorbed in an activity, time flies by. When we’re bored or waiting, it drags on endlessly.

Aristotle’s view also has implications for how we think about the nature of reality itself. If time depends on change, then perhaps change is more fundamental than we realize.

Maybe the universe’s constantly shifting, dynamic nature is what’s truly real, while the stable objects and entities we perceive are just temporary manifestations.

This is a mind-bending idea, but some modern physicists have echoed it. The theory of relativity, for instance, suggests that time is not absolute but relative to the observer’s motion.

In the end, Aristotle’s theory of time’s dependence on change is challenging and thought-provoking. It may not be the last word on the nature of time, but it certainly gives us plenty to ponder.

As we grapple with the mysteries of time and change, we can take some comfort in knowing that even the great minds of history struggled with these deep questions. Aristotle’s discussion reminds us that when it comes to time, there are no easy answers – only endless opportunities for wonder and exploration.

Key Takeaway: Aristotle on Time

Aristotle turns our usual thinking on its head by suggesting time can’t exist without change. This idea challenges the notion of time as fixed, proposing instead that it’s deeply tied to the ever-shifting world around us. It opens up a whole can of worms about whether time is real or just our perception, pushing us to rethink not just time but reality itself.

Aristotle on Time as a Number and Measure: Aristotle on Time

Aristotle’s take on time is a bit of a head-scratcher. But stick with me, and we’ll unravel this ancient mystery together.

In his work Physics, Aristotle makes a bold claim: time is a kind of number.

Not just any old number, though. Specifically, he calls it a “number of changes.”

Time as several Change

So, what does Aristotle mean by this? Well, he’s not saying that time is changing. Instead, he’s arguing that time is dependent on change.

Think of it like this: when we count time, we count instances of change. Each “now” we count off marks a point in the ongoing flow of change around us.

As philosopher Ursula Coope puts it, Aristotle defined time as essentially countable. We measure time by ticking off these countable nows.

“Aristotle defines time as a kind of ‘number of change’ with respect to the before and after. It is argued that this means that time is a kind of order (not, as is commonly supposed, that it is a kind of measure).”
– Ursula Coope, Time for Aristotle

In Aristotle’s view, time isn’t just a measuring stick we hold up to change. It’s woven into the very fabric of change itself. This is pretty deep stuff.

The Directionality of Time: Aristotle on Time

But wait, there’s more. Aristotle also has some thoughts on the directionality of time.

He sees time as a universal ordering system. It allows us to put all the various changes in the world into a coherent sequence—a before-and-after.

“It is a universal order within which all changes are related to each other.”
– Ursula Coope, Time for Aristotle

In other words, time points everything in the same direction. It’s the ultimate organizer.

Without this temporal order provided by time, the world would be a jumble of disconnected changes with no rhyme or reason. Time is the great connector.

Time as a Measure of Change

Now, you might be thinking – isn’t this all just a fancy way of saying that time measures change? Fair question.

But for Aristotle, it’s a bit more nuanced than that. Remember, he defines time as several changes, not a measure of change.

The difference is subtle but important. As Coope argues:

“It is argued that Aristotle defining time as a ‘number of change’ means that time is a kind of order (not, as is commonly supposed, that it is a kind of measure).”
– Ursula Coope, Time for Aristotle

So, while time can certainly be used to measure change, that’s not its defining feature in Aristotle’s eyes. At its core, time is the countable, orderly progression in which all change occurs.

It’s the backdrop against which the drama of change plays out – not just a handy tool for keeping track of it all.

Of course, this doesn’t mean Aristotle thinks time and measurement are unrelated. He spends much time (pun intended) exploring how we use time to measure change and vice versa.

But his key insight is that time is fundamentally about sequence and order, not just quantity and measurement. The drumbeat gives structure and direction to the dance of change.

So there you have it – a whirlwind tour of Aristotle’s thoughts on time, number, and measure. It’s a complex and often counterintuitive picture that rewards close examination.

The next time you count the seconds or marvel at the arrow of time, spare a thought for old Aristotle. He may just have been onto something.

Key Takeaway: Aristotle on Time

Aristotle rocked our world by saying time is not just a clock ticking but the rhythm of change itself. It’s all about counting moments of change, giving us an order to follow. This isn’t just measuring; it’s seeing how everything connects in a grand dance of before and after.

The Nature of the “Now” in Aristotle’s Account of Time: Aristotle on Time

Aristotle’s account of time in Physics IV has puzzled philosophers for centuries.

At the heart of his theory lies the concept of the “now” – but what exactly is this mysterious entity?

According to Aristotle, the now is a fundamental building block of time. It’s indivisible and serves as a limit between the past and future.

But the now is also strangely elusive. It’s constantly changing, never staying the same from one moment to the next.

This has led to some head-scratching questions. How can something indivisible underlie the apparent continuity of time? And if the now is always different, what ties together the flow of time?

The Indivisibility of the Now: Aristotle on Time

Aristotle is adamant that the now is indivisible. You can’t split it into parts.

Why not? Well, if the now could be divided, then it would have distinct parts—a beginning and an end. But then we’d have to ask: What separates those parts?

There is presumably another now. But then that now would also be divisible, launching us on an infinite regress of ever-smaller nows.

Aristotle wants to avoid that. For him, the now is a simple, partless limit. It divides the past from the future, but it can’t itself be divided.

As Coope puts it, “The now, for Aristotle, is essentially something that divides: it is defined as the boundary between the past and the future” (Coope, Time for Aristotle, p.111).

But how can something indivisible play this crucial role in the continuity of time? That’s a tricky question and one that has generated much debate among scholars.

For Aristotle, the now plays a role analogous to a point on a line.

Just as a point marks the boundary between two line segments, the now marks the boundary between the past and future.

This analogy has some interesting implications. Points aren’t parts of lines – rather, they are limits of line segments.

Similarly, Aristotle seems to think the now isn’t strictly a part of time. As he puts it, “The now is not a part: a part is a measure of the whole, which must be made up of parts. Time is not held to be made up of nows” (Phy. 218a6-8).

Instead, the now is the ever-changing boundary between the past and future. It separates the two temporal realms without being identical to either.

This makes the now quite different from our typical conception of instants or moments. The now is not a miniature chunk of time but a moving limit.

The Sameness and Difference of Nows

Aristotle’s view of the now leads him to some initially puzzling claims.

On the one hand, he wants to say that the now is always different—no two nows are the same. This underlies the passage of time, the constant flow from one moment to the next.

But he also claims there is a sense that the now is always the same. Here’s how he puts it:

“The now in one sense is the same, in another it is not the same. In so far as it is in succession, it is different . . . but its substratum is the same” (Phy. 219b12-15).

What does Aristotle mean by this? One way to understand it is in terms of the now’s formal vs. material aspects.

Formally, each now serves the same function – marking the boundary between past and future. In this sense, all nows are the same.

But materially, the now is always changing – the boundary constantly shifts as time marches on. No two nows are materially identical.

As Aristotle scholar Tony Roark explains, “The now is not self-identical over time, but it is always the same in form, i.e., the now is always the division between the past and the future” (Roark, Aristotle on Time, p.115).

This formal sameness of nows allows us to track the flow of time as a continuous progression, even while each particular now is unique.

So, for Aristotle, the now is a strange beast – indivisible yet ever-changing, different in material but the same in form.

This baffling nature of the now makes Aristotle’s account so challenging and fascinating even today.

Key Takeaway: Aristotle on Time

Aristotle’s take on time centers around the “now,” a concept that splits the past and future without being part of either. This indivisible, ever-changing point puzzles us with its role in making time flow yet staying constant in function.

Consequences of Aristotle’s Theory of Time: Aristotle on Time

Aristotle’s theory of time, as laid out in Physics IV, has some fascinating implications.

It’s a deep dive into the nature of time itself, raising some mind-bending questions about its finitude and infinity, continuity, and passage.

One of the most intriguing consequences of Aristotle’s theory is whether time is finite or infinite. It’s a real brain teaser.

On one hand, Aristotle argues that time depends on change. And he believes the universe is eternal, with no beginning or end to its motion. This suggests that time could be infinite, stretching back and forward without limit.

On the other hand, Aristotle also says that time is a kind of “number of change.” This implies that time is discrete and countable rather than an infinite continuum. He tosses that the universe could have existed for only “ten thousand years.”

So, is time finite or infinite? Aristotle doesn’t give a definitive answer, but his theory opens up the possibility that time could be either one. This paradox still puzzles philosophers today.

The Continuity of Time

Another consequence of Aristotle’s theory is the question of time’s continuity. Is time a smooth, unbroken flow? Or is it more like a series of discrete moments?

Aristotle’s view is that time is continuous but in a special way. He argues that time depends on the continuity of motion and change.

As Coope explains, for Aristotle, “time is a universal order within which all changes are related to each other.” It’s the overarching structure that unifies and connects all the moments of change.

But this continuity isn’t the same as infinite divisibility. Aristotle believes time is made up of indivisible “nows” or instants. Between any two nows, there is always the potential for another now.

It’s a bit like the continuity of the real number line. Between any two numbers, you can always find another number. But you can’t divide the line into infinitely tiny pieces.

In Aristotle’s view, time is continuous, but not in the sense of being an infinitely divisible quantity. It’s more of an ordered structure that relates moments of change.

Time and Temporal Passage: Aristotle on Time

Perhaps the most puzzling consequence of Aristotle’s theory is its implications for the passage of time. Does time really “flow” from past to future, or is that just an illusion?

Aristotle’s view is that time depends on the mind or soul to count nows before, and afters. This leads to some surprising conclusions.

For example, Aristotle argues that things that exist eternally, like the heavenly bodies, are not “in time.” They are not subject to the flow from past to future because their motion has no beginning or end.

This seems to go against our intuitive sense of time’s passage. We imagine time carrying everything forward, even eternal things. But for Aristotle, eternal motion is not “in time” in the same way that finite motions are.

Some scholars, like Chelsea Harry, argue that this doesn’t mean eternal things are outside of time altogether. They still stand in temporal relations, like before and after or simultaneous. But they are not subject to time as a measure of their motion.

Other interpreters, like Ursula Coope, suggest that, in Aristotle’s view, the apparent “flow” of time might be a feature of our perception rather than time itself. It arises from the way our minds count and compare motions.

So, Aristotle’s theory of time raises deep questions about temporal passage. Is the flow of time real or a product of our experience? Can eternal things be “in time”? There is still much debate over how to understand Aristotle’s view.

But one thing is clear: Aristotle’s account of time is not simple or straightforward. It’s a subtle and complex theory with challenging consequences for understanding the nature of time. Even today, scholars are still grappling with its implications.

Key Takeaway: Aristotle on Time

Aristotle’s deep dive into time leaves us with brain teasers like whether time is finite or infinite, if it flows smoothly or in discrete moments, and how eternal things fit into the timeline. He suggests time could be both countable and endless, continuous yet made of indivisible “nows”, challenging our perception of its flow. This paradox sparks ongoing debates among philosophers today.

Conclusion: Aristotle on Time

In wrapping up our journey through “Aristotle on Time,” it becomes clear that this isn’t just about ancient texts gathering dust. It’s about unpacking concepts that have shaped human thought for millennia—ideas that continue to influence how we perceive our world today. As we’ve seen, AI quietly supports many facets of modern life without much fanfare or terror as Hollywood suggests. Similarly, revisiting Aristotle helps demystify one of life’s constants and invites us to appreciate how it impacts everything from daily chores to deep philosophical inquiries.

So next time you glance at your watch or schedule your day remember—the threads linking us back to Aristotle are woven into these moments; his insights remain as relevant now as they were then.
