Infinity is defined as something which is potentially without any limit. According to some philosophers the infinite is dependent on finite. If the concept of finite was not existent, then the concept of infinite would also be non existent. Each signifies the others importance. The existence of finite makes one think of or gives a vision of the infinite.

Eastern philosophy relates infinite to the spirit. Even in Western Philosophy infinity has been considered as the ultimate or the absolute.

The discussion of infinity crosses the realms of three disciplines. These disciplines are philosophy, mathematics and theology. It is truly said the beginning of philosophy starts where mathematics ends. Mathematics can explain the finite. Philosophy can explain the infinite.

I once talked to one of my acquaintance if knows something about infinity. The answer was something which has no end and is not easily comprehensible.

I gave him example of a set of numbers {1, 2, 3, 4....... }. Let us start with the number 2. When it is multiplied by itself it becomes four. When it is multiplied by itself a hundred times it becomes a very big number. What will happen when we will multiply the very big number a hundred times by itself? Shall it be the biggest number and if not what will be the biggest number. How long can we go on doing this?

This all signifies that infinity is potentially without limits.

In words of the Italian astronomer Galileo
"So far as I see we can only infer that the totality of all numbers is infinite, that the number of squares is infinite, and that the number of their roots is infinite; neither is the number of squares less than the totality of all numbers, nor the latter greater than the former; and finally the attributes "equal," "greater," and "less," are not applicable to infinite, but only to finite, quantities."
