The quote by Arthur Edward Waite suggests that what is often termed as "Parisian Diabolism" is a specific form of Black Magic found in grimoires, rather than embodying the profound wickedness associated with the more sinister practitioners known as the Brothers of the Left Hand Path. Waite implies that the latter group personifies evil and engages in spiritual malevolence that transcends typical magical practices.
This distinction indicates that while Parisian Diabolism may contain elements of black magic, it lacks the depth of moral depravity that characterizes the sinister traditions associated with the Left Hand Path. Waite's commentary hints at a broader understanding of magical practices, highlighting varying degrees of moral implications within different forms of magic.
