Van Reeth is the only daughter in a family of four children.[1] She is of Flemish origin by her paternal grandfather. Daughter of an archivist, she moved a lot in her childhood due to her father's assignments.[2]
While she is eligible for the oral examinations of the philosophy agrégation, she finally prefers to leave this path to work in radio.[2] Since September 2011, on France Culture, she has been producing and hosting the daily philosophy program Les Nouveaux Chemins de la connaissance alongside Raphaël Enthoven[9] which was renamed Les Chemins de la philosophie in 2017. In December 2012, this program became the most downloaded show of Radio France,[10] and maintains this position from time to time.[11]
In March 2014, she launched a series entitled "Questions de Caractère". (co-edition Plon (publisher) / France Culture): she interacts with contemporary philosophers while keeping the spirit and approach of her program. The first volume, co-written with Jean-Luc Nancy, deals with jouissance, a theme on which she has already spoken several times.
On December 19, 2017, it was announced that Van Reeth would take over from Jean-Pierre Elkabbach and host the new literary program of Public Sénat, still recorded in the Senate Library,[12]Livres & Vous.
