Well known in philosophy and mathematics, the so-called paradox of Tristram Shandy was introduced by Bertrand Russell in his book The Principles of Mathematics to evidentiate the inner contradictions that arise from the assumption that infinite sets can have the same cardinality  —as would be the case with a gentleman who spends one year to write the story of one day of his life, if he were able to write for an infinite length of time. The paradox depends upon the fact that "the number of days in all time is no greater than the number of years".
