## What is infinity philosophically?

In philosophy and theology, infinity is explored in articles under headings such as the Absolute, God, and Zeno’s paradoxes. In Judeo-Christian theology, for example in the work of Duns Scotus, the infinite nature of God invokes a sense of being without constraint, rather than a sense of being unlimited in quantity.

## Is infinity a metaphysical concept?

Infinity in Physical Science. From a metaphysical perspective, the theories of mathematical physics seem to be ontologically committed to objects and their properties. If any of those objects or properties are infinite, then physics is committed to there being infinity within the physical world.

**Is time infinite in philosophy?**

Temporal finitism is the doctrine that time is finite in the past. The philosophy of Aristotle, expressed in such works as his Physics, held that although space was finite, with only void existing beyond the outermost sphere of the heavens, time was infinite.

### What is the history of infinity?

The ancient Greeks expressed infinity by the word apeiron, which had connotations of being unbounded, indefinite, undefined, and formless. Both Plato (428/427–348/347 bce) and Aristotle (384–322 bce) shared the general Greek abhorrence of the notion of infinity.

### Why is infinity important in math?

Infinity is often used in describing the cardinality of a set or other object (such as a list or sequence of terms) that does not have a finite number of elements. The concept of infinity is extremely important in a variety of contexts, most notably calculus and set theory.

**Can humans understand infinity?**

This goes to show that everything depends on perception. For many of us, it’s easy to understand the concept of infinity, but we can’t comprehend how “big” or “never-ending” it is, because our perception of time always has a beginning and an end — minutes, days, years, lifespans.

**Is infinity a real number in math?**

Infinity is a “real” and useful concept. However, infinity is not a member of the mathematically defined set of “real numbers” and, therefore, it is not a number on the real number line. One of the most common definitions to learn then is that the real numbers are the set of Dedekind cuts of the rational numbers.
