The concepts and structures of Jewish Kabbalah have been used in the contemporary world to open comparative dialogue and cross-fertilization with modern secular disciplines in the Sciences and Humanities. This has been an uncommon phenomenon, since it requires wide internal understanding of both traditionalist Kabbalah and modern secular thought, and for social reasons Jewish modernity has seen isolation and entrenchment between the two. Skilled authorities in both traditions have included contemporary traditionalist Orthodox teachers of Kabbalah, as well as Neo-Kabbalistic and Academic scholars who read Kabbalah in a critical, universalist way.
