Dickens was not the very first author to celebrate the Christmas season in literature, but it was he who superimposed his humanitarian vision of the holiday upon the public, an idea that has been termed as Dickens's "Carol Philosophy". Dickens believed the best way to reach the broadest segment of the population regarding his concerns about poverty and social injustice was to write a deeply felt Christmas story rather than polemical pamphlets and essays. Dickens's career as a best-selling author was on the wane, and the writer felt he needed to produce a tale that would prove both profitable and popular. Dickens's visit to the work-worn industrial city of Manchester was the "spark" that fired the author to produce a story about the poor, a repentant miser, and redemption that would become A Christmas Carol
