Letter from Heinrich Marx to his son Karl (2 March 1837)

At times my heart delights in thinking of you and your future. And yet at times I cannot rid myself of ideas which arouse in me sad forebodings and fear when I am struck as if by lightning by the thought: is your heart in accord with your head, your talents? Has it room for the earthly but gentler sentiments which in this vale of sorrow are so essentially consoling for a man of feeling? And since that heart is obviously animated and governed by a demon not granted to all men, is that demon heavenly or Faustian? Will you ever -- and that is not the least painful doubt of my heart -- will you ever be capable of truly human, domestic happiness? Will -- and this doubt has no less tortured me recently since I have come to love a certain person [Marx's then-fiancee, Jenny von Westfalen] like my own child -- will you ever be capable of imparting happiness to those immediately around you?

About Karl Marx

Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German political philosopher, economist, historian, sociologist, journalist and revolutionary socialist. Marx's work in economics laid the basis for labor theory of value, and has influenced much of subsequent economic thought. He published many works during his lifetime, including The Communist Manifesto (1848) and the first volume of Das Kapital (1867), the two later volumes being completed by his collaborator Friedrich Engels.
