### Berry’s paradox

We can classify the integers based on the smallest number of syllables in English necessary to describe them. For example, 6 could be described in one syllable as “six,” while 729 could be described in two syllables as “nine cubed.”

Since there are only a finite number of words in the English language, only a finite (although very large) number of numbers can be described with a given number of syllables. Specifically, for the purpose of this argument, only a finite number of positive integers can be described using 18 or fewer syllables. Therefore, there must be a least integer not describable using less than 19 syllables.

Now, consider the set of all positive integers that require at least 19 syllables to describe them. This set will have a smallest element. However, we can describe this integer as the “least integer not describable using less than nineteen syllables”, which is a description of 18 syllables!

Views of the Tesseract Posterby theFOUNDRY. A tesseract is the four-dimensional analog of the cube; the tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of 6 square faces, the hypersurface of the tesseract consists of 8 cubical cells.
