Karl Marx' father Heinrich:
Alas, your conduct has consisted merely in disorder, meandering in all the fields of knowledge, musty traditions by sombre lamplight; degeneration in a learned dressing gown with uncombed hair has replaced degeneration with a beer glass. And a shirking unsociability and a refusal of all conventions and even all respect for your father. Your intercourse with the world is limited to your sordid room, where perhaps lie abandoned in the classical disorder the love letters of a Jenny [Karl’s fiancée] and the tear-stained counsels of your father. … And do you think that here in this workshop of senseless and aimless learning you can ripen the fruits to bring you and your loved one happiness? … . As though we were made of gold my gentleman son disposes of almost 700 thalers in a single year, in contravention of every agreement and every usage, whereas the richest spend no more than 500.
