Regrets on my old dressing gown is a Essai written by Denis Diderot in 1768.

This part, looked like one of most charming of Diderot, was published the following year in the Correspondance literary of Grimm and published in volume in 1772 in a booklet small in-8°, without indication of place, but certainly leaving a Swiss printing works.

The writer had rendered a service announced to Marie-Therese Geoffrin, famous by the literary living room which it held with such an amount of distinction. To testify its recognition to him, it was dawning one to move all movable poor of the philosopher and replaced them by others which, though more beautiful and better, did not deserve however, appears it, a so pompeux praise. The reader will notice an admirable appreciation of the talent of the painter Vernet.

With more large scales, this small text, written on an ironic tone, is pretext with a soft-bitter reflection on the destiny of the philosophers vis-a-vis prosperity and the compromises to which the growing old intellectual can, the helping age, to let itself go: “My friends, keep your old friends. My friends, fear the attack of the richness. That my example informs you. Poverty has its franknesses; opulence has its embarrassment”.
