Fragments and testimonies
Fragments attributed to Heraclitus address logos, opposites, change and cosmic order. Modern editions collect quotations from different authors: their order and interpretation do not automatically reconstruct the lost book.
Understanding the text
Standard numbers derive from Diels–Kranz; later editions distinguish witnesses, context and wording differently. The authenticity and translation of some passages remain contested.
Editorial reconstruction from ancient quotations; no complete manuscript survives.

Listening for logos
Enter the fragments without turning difficulty into mystification.
Logos
A common order or account calls for listening beyond private opinion; the precise meaning of the word is disputed. Identify the ancient source preserving the passage and distinguish its words from modern interpretation.
Opposites
Tensions such as waking and sleeping may be related without becoming simply identical. Compare this idea with another witness: an isolated quotation does not automatically restore its lost context.
Change
River and fire images illuminate continuity through transformation without licensing a single slogan. Note what the document permits you to conclude and what remains a hypothesis about the philosopher’s thought.
Questions to carry into your reading
- Which meaning of logos does each translation favor?
- Which opposites remain distinct within unity?
Compare at least two translations with the ancient witness and keep uncertainties about context visible.
