My business, my art, is to live my life. If anyone forbids me to talk about it according to my own sense, experience and practice, let him also command an architect to talk about buildings not according to his own standard but his next-door neighbour’s, according to somebody else’s knowledge not his own.

[Mon mestier & mon art, c’est vivre. Qui me defend d’en parler selon mon sens, experience & usage : qu’il ordonne à l’architecte de parler des bastimens non selon soy, mais selon son voisin, selon la science d’un autre, non selon la sienne.]

Michel de Montaigne (1533–1592) French essayist

Essays, Book 2, ch. 6 (2.6), “Of Practice [De l’exercitation]” (1574?) [tr. Screech (1987)]

My arte and profession, is to live. Who forbids mee to speake of it, according to my sense, experience, and custome? Let him appoint the Architect to speake of buildings, not according to himselfe, but his neighbours, according to anothers skill, and not his owne.
[tr. Florio (1603)]

My art and business is to live. He that forbids me to speak according to my own sense, experience, and practice, may as well enjoin an architect to speak of buildings not in his own style, but in his neighbour's; not according to his own science, but according to another man's.

[tr. Cotton/Hazlitt (1877)]

My profession and my art is living.

Living is my job and my art.
[ed. Rat (1958)]
