“My suffering left me sad and gloomy.”

Elegy 2 (First version)
Roman Elegies (1789)

Song Walk On By

... The perspective on ourselves that we get when we take the point of view of the universe also yields as much objectivity as we need if we are to find a cause that is worthwhile in a way that is independent of our own desires. The most obvious such cause is the reduction of pain and suffering, wherever it is to be found.

Variant: A Very Short Song

Once, when I was young and true,
Someone left me sad-
Broke my brittle heart in two;
And that is very bad.

Love is for unlucky folk,
Love is but a curse.
Once there was a heart I broke;
And that, I think, is worse.

Letter from Naples, Italy to Otto Grautoff (1896); as quoted in A Gorgon's Mask: The Mother in Thomas Mann's Fiction (2005) by Lewis A. Lawson, p. 34
Context: I think of my suffering, of the problem of my suffering. What am I suffering from? From knowledge — is it going to destroy me? What am I suffering from? From sexuality — is it going to destroy me? How I hate it, this knowledge which forces even art to join it! How I hate it, this sensuality, which claims everything fine and good is its consequence and effect. Alas, it is the poison that lurks in everything fine and good! — How am I to free myself of knowledge? By religion? How am I to free myself of sexuality? By eating rice?
