Daniel is a Jewish humanist in the tradition of the French Left. He was a former colleague and friend of Albert Camus, a fellow pied-noir. In La prison juive: Humeurs et méditations d'un témoin (The Jewish Prison), Daniel argues that prosperous, assimilated Jews in the west live in a self-imposed prison made of up of three invisible walls: the idea of the Chosen People, Holocaust remembrance, and support for Israel. "Having trapped themselves inside these walls...," wrote Adam Shatz in describing the book, "they were less able to see themselves clearly, or to appreciate the suffering of others -- particularly the Palestinians living behind the 'separation fence'."
Daniel co-founded the French magazine Le Nouvel Observateur. The magazine had already existed since 1950 and initially called L'Observateur politique, économique et littéraire. It had turned to L'Observateur aujourd'hui in 1953 and France Observateur in 1954. The name Le Nouvel Observateur was adopted in 1964.
The 1964 incarnation of the magazine was when Jean Daniel and Claude Perdriel took over renaming the magazine and starting its best known phase under the name Le Nouvel Observateur as a weekly. Since then it has been published by Groupe Nouvel Observateur on a weekly basis and has covered political, business and economic news in France and internationally. On 23 October 2014, the magazine was renamed L'Obs.
