Aristotle (384-322 BC), an ancient Greek philosopher, believed that infinity could exist, because a finite quantity was infinitely separable and could not reach the pole, but infinity was universally acknowledged as unreachable.

/kloc-in the 20th century, a great Indian mathematician, Bascara, appeared, and his concept was close to that of modern theorization.
