What is time in a philosophical sense?
There is general agreement among philosophers that time is continuous (i.e. we do not experience it as stopping and starting, or darting about at random), and that it has an intrinsic direction or order (i.e. we all agree that events progress from past to present to future). …
Does time require change?
He said, “that time is not change [itself]” because a change “may be faster or slower, but not time….” (Physics, chapter 10). For example, a leaf can fall faster or slower, but time itself cannot be faster or slower.
What does Aristotle say about time?
Aristotle claims that time is not a kind of change, but that it is something dependent on change. He defines it 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).
What did Plato say about time?
Plato clearly says that time is the wanderings of these bodies – their movement – and not a kind of number that measures such movement. Abstracting time from motion was an innovation of Aristotle’s. For Plato, time just is celestial motion. Note that time applies, strictly speaking, only to the realm of becoming.
What is the concept of time?
Physicists define time as the progression of events from the past to the present into the future. Basically, if a system is unchanging, it is timeless. Time can be considered to be the fourth dimension of reality, used to describe events in three-dimensional space.
Does time actually flow?
This world line is a fixed object in four dimensional spacetime – it doesn’t change with time. All that changes is the ball’s position on the world line. This is why we say that time doesn’t flow. Time is just one of the four dimensions that the world line occupies.
What is the relationship between time and change?
It seems that change and time are inseparable: changes take time; are located and ordered in time; and they are separated by time. The inseparability of time and change is a kind of logical truth. Time, it has often been said, stops everything from happening at once.
How does time relate to change?
It has no beginning and no end. This is the actual meaning of Special Relativity: time is relative, its speed changes with the speed of the inertial system. The faster the speed of the system the slower is the speed of time (change).
Why does Aristotle say that there is no time without change?
On this standard interpretation, Aristotle starts from the premise that it is impossible to know that time has passed with- out knowing that there has been some change and argues, on the basis of this, that there is no time without change.
What is known about time?
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. Time is often referred to as a fourth dimension, along with three spatial dimensions.
Who defined time?
In Physics, the Greek thinker Aristotle spelled out a fairly modern-sounding definition of time as “the calculable measure of motion with respect to before and afterness.” This idea of time as a fixed sequence of events would survive with only minor modifications until the work of Einstein in the early 20th century.
What is the beginning of time?
The conclusion of this lecture, is that the universe has not existed for ever. Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down.
What is the philosophy of time in philosophy?
Philosophy of Time. But a whole host of other philosophical issues related to time have also surfaced, including whether time is tensed or tenseless, whether the present is instantaneous or a duration, whether the past and the future can be said to really exist, the manner in which objects persist though time, etc.
What are the philosophical issues related to time?

What do philosophers of time want to build?
Philosophers of time want to build a robust and defensible philosophical theory of time, one that resolves the issues on the list of philosophical issues mentioned in the opening summary.
Is there a consensus among philosophers of time?
Unfortunately, there is no consensus among philosophers of time about what counts as a good reason, although there is among physicists. Does conflict with relativity theory count as a good reason?
