In sharp and clear contrast the set just considered is a readily finished, locked infinite set, fixed in itself, containing infinitely many exactly defined elements (the natural numbers) none more and none less. (Y. Manin [3]), There is no actual infinity, that the Cantorians have forgotten and have been trapped by contradictions. From the division of magnitudes – for the mathematicians also use the notion of the infinite. (Georg Cantor)[10] (G. Cantor [8, p. 252]), One proof is based on the notion of God. In its daring flight the infinite reached dizzying heights of success. Proponents of intuitionism, from Kronecker onwards, reject the claim that there are actually infinite mathematical objects or sets. Anaximander (610–546 BC) held that the apeiron was the principle or main element composing all things. It's just infinity. Levy 1984, This page was last edited on 29 May 2020, at 19:12. would it be undefined, 0, or all positive real numbers? morale 14 (1906) p. 316]), When the objects of discussion are linguistic entities [...] then that collection of entities may vary as a result of discussion about them. Find the image of the triangle having vertices(1, 2),(3, 4),(4, 6)under the translation that takes the point(1, 2) to(9, 1) These might include the set of natural numbers, extended real numbers, transfinite numbers, or even an infinite sequence of rational numbers. Or is it an imaginary number. The ancient Greek term for the potential or improper infinite was apeiron (unlimited or indefinite), in contrast to the actual or proper infinite aphorismenon. (J. Baconthorpe [9, p. 96]). [14] Georg Cantor is the most significant mathematician who defended actual infinities, equating the Absolute Infinite with God. If you use ZF set theory (with or without the Axiom of Choice), you can for any infinite cardinal construct one which is … First, from the highest perfection of God, we infer the possibility of the creation of the transfinite, then, from his all-grace and splendor, we infer the necessity that the creation of the transfinite in fact has happened. "For the fact that the process of dividing never comes to an end ensures that this activity exists potentially, but not that the infinite exists separately.". There is no "absolute answer" as to whether there is an absolute infinity, because whether or not you can have an absolute infinity is a function of what mathematical formalism you use. Find its width.? There were exceptions, however, for example in England. Neither is it present in nature nor is it admissible as a foundation of our rational thinking – a remarkable harmony between being and thinking. (D. Hilbert [6, 190]), Infinite totalities do not exist in any sense of the word (i.e., either really or ideally). [5, p. 255]), Intuitionists reject the very notion of an arbitrary sequence of integers, as denoting something finished and definite as illegitimate. (Aristotle)[5], Belief in the existence of the infinite comes mainly from five considerations:[6], Aristotle postulated that an actual infinity was impossible, because if it were possible, then something would have attained infinite magnitude, and would be "bigger than the heavens."
