I came upon this article by Evola on Joseph de Maistre:
http://www.geocities.com/CapitolHill/1404/maistre.html
In it, Evola mentions that Masonry at the time of de Maistre was different
from its later incarnations. ("nel quadro della massoneria, la quale a quel
tempo era assai diversa da quella più recente, tanto che lo stesso de
Maistre ne fece parte")
Though it seems that de Maistre was actually involved with Martinism.
The rest of the book review may be of interest to some. While Evola rejects
de Maistre's Christian concept of divine Providence, there are other aspects
of his thought (which stem from the esoteric current in de Maistre derived
from Louis Claude de St Martin) that appeal to Evola.
