Second nature

Is a settled habit a kind of nature? Second nature is the saying that a habit, once formed, acts as firmly as the character a person was born with. These readings ask how far that comparison holds, and which of the two is the stronger.

Aristotle’s Nicomachean Ethics, Book VII, treats “incontinence” (akrasia) and how curable its forms are. At the close of chapter 10 he cites the poet Evenus on “habit” and “nature”, after comparing the one who is incontinent “through habituation” with the one in whom it is “innate”. The lines are among the best known on the subject, and they sit here as the place where habit and nature are named together.

Thought 93 of Pascal’s Pensées, in the usual English numbering of the Brunschvicg edition, is a short fragment on “nature” and “custom” that begins from the fear of “parents” for their children’s “natural love”. The Pensées are notes for an apology for the Christian religion, left unfinished at his death in 1662. It stands under this term for the phrase “second nature” and its inversion.

Chapter IV of William James’s The Principles of Psychology (1890) is titled “Habit”. He opens a passage on the “veteran soldier” with the remark attributed to the “Duke of Wellington”, “Habit is ten times nature”. It stands under this term for the saying that sets habit beside nature.
