 Scholars of esotericism such as Godwin and Faivre differentiated the tradition of religious illumination from the religious system established in the late nineteenth century by Helena Blavatsky by referring to the latter with a capital letter as Theosophy, and the former with a lower-case letter as theosophy.Followers of Blavatsky's movement are known as Theosophists, while adherents of the older tradition are termed theosophers.Several Theosophists — such as C. C. Massey and Franz Hartmann — were also theosophers.
