Part of That Power Which Always Wills the Bad and Works the Good

The expression “Part of That Power Which Always Wills the Bad and Works the Good” is Mephistopheles’s paradoxical account of what he is: an element of a power whose intention and effect diverge. In a few words, it presents evil not as an independent force capable of controlling every outcome, but as something that can unwittingly serve a good beyond its will.

The Question of Identity

The exchange begins when Faust observes that names generally express the nature of what they name. He points to names such as Beelzebub, Destroyer, and Father of Lies as examples whose meaning is readily apparent, then asks Mephistopheles to identify himself. Mephistopheles answers with the expression, which casts his identity as part of a larger and not fully understood power rather than as a simple name for evil.

The Paradox of Intention and Effect

The statement turns on the contrast between willing the bad and working the good. Mephistopheles’s will is directed toward evil, but the effects attributed to the power of which he is a part may be good. The wording therefore separates intention from consequence: destructive desire does not guarantee that destruction will be the final result.

Its qualification that the power is not understood also leaves the relation between the two outcomes unresolved. Mephistopheles offers a concise definition, but not a full explanation of how evil comes to produce good. The answer gives Faust a riddle to interpret rather than a transparent account of the speaker’s nature.

Dramatic Function

Faust immediately asks what hidden meaning the enigma contains. His response keeps the expression from functioning as a settled doctrine: it becomes the opening of a problem about agency, moral purpose, and unintended results. Mephistopheles can describe himself through evil intention, yet his own formulation places that intention within a power whose work exceeds it.

The expression’s force lies in this tension between a will and its outcome. It establishes a frame in which Mephistopheles may act as an adversarial force without being the sole author of what follows; the good that results is not presented as his aim, but as an effect that complicates his claim to define himself.
