Georg Cantor quotes

The essence of mathematics lies precisely in its freedom.
 Georg Cantor 
To ask the right question is harder than to answer it.
 Georg Cantor 
A false conclusion once arrived at and widely accepted is not easily dislodged and the less it is understood the more tenaciously it is held.
 Georg Cantor 
A set is a Many that allows itself to be thought of as a One.
 Georg Cantor 

In mathematics the art of proposing a question must be held of higher value than solving it.
 Georg Cantor 
The actual infinite arises in three contexts: first when it is realized in the most complete form, in a fully independent otherworldly being, in Deo, where I call it the Absolute Infinite or simply Absolute; second when it occurs in the contingent, created world; third when the mind grasps it in abstracto as a mathematical magnitude, number or order type.
 Georg Cantor 
The fear of infinity is a form of myopia that destroys the possibility of seeing the actual infinite, even though it in its highest form has created and sustains us, and in its secondary transfinite forms occurs all around us and even inhabits our minds.
 Georg Cantor 
Every transfinite consistent multiplicity, that is, every transfinite set, must have a definite aleph as its cardinal number.
 Georg Cantor 

In mathematics, the art of asking questions is more valuable than solving problems.
 Georg Cantor 
There is no doubt that we cannot do without variable quantities in the sense of the potential infinite. But from this very fact the necessity of the actual infinite can be demonstrated.
 Georg Cantor 
What I assert and believe to have demonstrated in this and earlier works is that following the finite there is a transfinite (which one could also call the suprafinite), that is an unbounded ascending lader of definite modes, which by their nature are not finite but infinite, but which just like the finite can be determined by welldefined and distinguishable numbers.
 Georg Cantor 
The transfinite numbers are in a certain sense themselves new irrationalities and in fact in my opinion the best method of defining the finite irrational numbers is wholly disimilar to, and I might even say in priciple the same as, my method described above of introducing trasfinite numbers. One can say unconditionally: the transfinite numbers stand or fall with the finite irrational numbers; they are like each other in their innermost being; for the former like the latter are definite delimited forms or modifications of the actual infinite.
 Georg Cantor 

Use Campaign link tagging labels all for specifying slight differences in content for split testing.
 Georg Cantor 
The potential infinite means nothing other than an undetermined, variable quantity, always remaining finite, which has to assume values that either become smaller than any finite limit no matter how small, or greater than any finite limit no matter how great.
 Georg Cantor 
The old and oftrepeated proposition "Totum est majus sua parte" [the whole is larger than the part] may be applied without proof only in the case of entities that are based upon whole and part; then and only then is it an undeniable consequence of the concepts "totum" and "pars". Unfortunately, however, this "axiom" is used innumerably often without any basis and in neglect of the necessary distinction between "reality" and "quantity", on the one hand, and "number" and "set", on the other, precisely in the sense in which it is generally false.
 Georg Cantor 
Had MittagLeffler had his way, I should have to wait until the year 1984, which to me seemed too great a demand!
 Georg Cantor 

The transfinite numbers are in a sense the new irrationalities [ ... they] stand or fall with the finite irrational numbers.
 Georg Cantor 
Don't always blindly follow guidance and stepbystep instructions; you might run into something interesting.
 Georg Cantor 
This view [of the infinite], which I consider to be the sole correct one, is held by only a few. While possibly I am the very first in history to take this position so explicitly, with all of its logical consequences, I know for sure that I shall not be the last!
 Georg Cantor 
My theory stands as firm as a rock; every arrow directed against it will return quickly to its archer. How do I know this? Because I have studied it from all sides for many years; because I have examined all objections which have ever been made against the infinite numbers; and above all because I have followed its roots, so to speak, to the first infallible cause of all created things.
 Georg Cantor 

Great innovation only happens when people aren't afraid to do things differently.
 Georg Cantor 
I am so in favor of the actual infinite that instead of admitting that Nature abhors it, as is commonly said, I hold that Nature makes frequent use of it everywhere, in order to show more effectively the perfections of its Author. Thus I believe that there is no part of matter which is not  I do not say divisible  but actually divisible; and consequently the least particle ought to be considered as a world full of an infinity of different creatures.
 Georg Cantor 
I entertain no doubts as to the truths of the tranfinites, which I recognized with God's help and which, in their diversity, I have studied for more than twenty years; every year, and almost every day brings me further in this science.
 Georg Cantor 
My beautiful proof lies all in ruins.
 Georg Cantor 

I realize that in this undertaking I place myself in a certain opposition to views widely held concerning the mathematical infinite and to opinions frequently defended on the nature of numbers.
 Georg Cantor 
I like creativity in data collection. Here are a few creative Google Analytics tracking ideas I have seen:
 Georg Cantor 
Mathematics is entirely free in its development, and its concepts are only linked by the necessity of being consistent, and are coordinated with concepts introduced previously by means of precise definitions.
 Georg Cantor 
Mathematics, in the development of its ideas, has only to take account of the immanent reality of its concepts and has absolutely no obligation to examine their transient reality.
