Lucian Blaga was the creator of a speculative and metaphoric philosophical system that placed mystery at its very core. Mystery, according to Blaga, veils existence and represents both a stimulus and a brake for human knowledge. His articulation of this view is strongly indebted to Kant, whose transcendental philosophy he sought to extend by critically examining the forms of sensibility and categories of the understanding, not so much in relation to consciousness, but as they are duplicated, or doubled, in the unconscious. The result is Blaga's stylistic apriorism, according to which the unconscious always manages consciousness through abyssal categories in terms of which different regions and peoples at once reveal and remain isolated from mystery.
