In this usage, infinity is a mathematical concept, and infinite mathematical objects can be studied, manipulated, and used just like any other mathematical object.

Infinity (philosophy)

In philosophy and theology, infinity is explored in articles under headings such as the Absolute, God, and Zeno's paradoxes.

In Greek philosophy, for example in Anaximander, 'the Boundless' is the origin of all that is. He took the beginning or first principle to be an endless, unlimited primordial mass (?πειρον, apeiron). The Jain metaphysics and mathematics were the first to define and delineate different "types" of infinities. The work of the mathematician Georg Cantor first placed infinity into a coherent mathematical framework. Keenly aware of his departure from traditional wisdom, Cantor also presented a comprehensive historical and philosophical discussion of infinity.[1]

ドロステ効果（ドロステこうか、オランダ語：Droste-effect）とは、再帰的な画像[1]（紋章学における紋中紋）のもたらす効果のこと。あるイメージの中にそれ自身の小さなイメージが、その小さなイメージの中にはさらに小さなイメージが、その中にもさらに……と画像の解像度が許す限り果てしなく描かれる。ドロステ効果は、自己言及システムの不思議の環(strange loop)の視覚的例である。
