Who really said it

What does not kill me makes me stronger

Written by Friedrich Nietzsche 1844–1900 · German philosopher & philologist
Verified Free to reuse

This is genuinely Nietzsche. It is aphorism 8 of the “Maxims and Arrows” section of Twilight of the Idols (Götzen-Dämmerung, 1888): “Was mich nicht umbringt, macht mich stärker.” The popular English is a near-literal rendering of that line.

Location
“Maxims and Arrows,” aphorism 8
First published
1888 (German)
Translation
Anthony M. Ludovici, 1911 (“That which does not kill me, makes me stronger”)

Aus der Kriegsschule des Lebens. — Was mich nicht umbringt, macht mich stärker. (“Out of life’s school of war — what does not kill me makes me stronger.”)

The line is the whole of aphorism 8; its first clause — “from life’s school of war” — is almost always dropped in popular use.

How we know

  • Wikipedia ↗ traces the line to aphorism 8 of “Maxims and Arrows” in Twilight of the Idols (1888): “Was mich nicht umbringt, macht mich stärker.”
  • The exact wording appears in Anthony Ludovici’s 1911 English translation on Project Gutenberg ↗ as “That which does not kill me, makes me stronger,” under the heading “From the military school of life.”
  • The German original was published in 1888, placing the source text firmly in the public domain.
Public domain

The source work, Nietzsche’s Twilight of the Idols, was first published in German in 1888 — long in the public domain. Early English translations such as Anthony Ludovici’s (1911) are also public domain; the popular wording is a near-literal rendering of the 1888 German, though some specific modern translations remain under their own copyright.

This reflects the original work, which is public domain. If your exact English wording comes from a specific modern translation, that translation may itself still be under copyright — check the edition you quote.

Fact-check

Genuine quote, mangled wording

The attribution to Nietzsche is correct — but the line is one of the most-misquoted sentences in English. Nietzsche wrote “me,” and framed it as the survivor’s hard-won lesson, not a blanket promise.

Popular paraphrase misquote

The most common English form swaps Nietzsche’s first-person “me” for a universal “us.” The original ↗ is singular: “Was mich nicht umbringt” — “what does not kill me.”

Pop-culture form paraphrase

The second-person “you” version was cemented by Kelly Clarkson’s 2011 hit “Stronger (What Doesn’t Kill You).” It captures the sentiment but is not Nietzsche’s wording.

The real line is Nietzsche’s own, from Twilight of the Idols (1888): “Was mich nicht umbringt, macht mich stärker ↗” — “What does not kill me makes me stronger.”

Context

Why it mattered

The aphorism sits under the sub-heading “Aus der Kriegsschule des Lebens” — from life’s school of war. For Nietzsche it was not a feel-good slogan but a claim about how strong individuals metabolise suffering into growth; the dropped first clause and the shift to “us/you” have softened it into the motivational mantra it is today.

Was mich nicht umbringt, macht mich stärker.

About Friedrich Nietzsche

Friedrich Nietzsche

1844–1900 · German philosopher & classical philologist

Friedrich Nietzsche was a German philosopher whose work on morality, power and the individual reshaped modern thought. Twilight of the Idols (1888) was among his last books before his 1889 breakdown, written as a rapid-fire “philosophy with a hammer.” Its opening “Maxims and Arrows” are terse aphorisms — one of which became this famous line.
