Here we see Bitzer as the personification of the Gradgrind philosophy. Although Gradgrind pleads with Bitzer to release Tom, Bitzer is cold to any sort of sympathy or human conscience. Bitzer is the "by the book" person he was schooled to be. Bitzer does what is best for himself, he concludes that if he turns Tom in to Bounderby then Bounderby will give him Tom's old job. Bitzer thus lives up to "fundamental principle of the Gradgrind philosophy, that everything was to be paid for. Nobody was ever on any account to give anybody anything or render anybody help without purchase."
