Franz Xaver von Baader

Bavarian Catholic philosopher and theologian (1765–1841), the Munich collaborator and credited precursor of Schelling in the *Philosophical Investigations into the Essence of Human Freedom* (1809). Schelling explicitly credits Baader with the disease-analogy (the "most fitting" comparison for evil) and the formulation that evil resides in a positive perversion or reversal of the principles — the technical heart of Schelling's positive evil doctrine. Baader's short essay "On the Assertion That There Can Be No Wicked Use of Reason" is reprinted as the second Supplementary Text to the Freedom Essay volume. The relationship is more than influence: Baader is Schelling's primary acknowledged precursor on the specific point of evil-as-positive — and through Baader, the wider tradition of Böhmean theosophy reached Schelling's metaphysics. Trained originally as a physician, employed by the Bavarian mining industry, ennobled in 1808; co-founder of the University of Munich in 1826.

Key Points

Born 1765 in Munich (six years before Hegel, ten years before Schelling); trained as a physician and mining engineer; first encountered Böhme c. 1786; became principal interpreter of Böhme into Schellingian-Idealist vocabulary.
The disease-analogy (Schelling's explicit attribution at Freedom Essay p. 481): "the most fitting comparison here is offered by disease, which, as the analogue [Gegenbild] of evil, is of much greater significance than commonly believed." Disease emerges when "I-hood enters as ruling into the periphery" (Baader's formulation, quoted at Freedom Essay p. 487).
"Positive perversion or reversal of the principles" (Schelling's explicit attribution at Freedom Essay p. 485): the technical formulation of evil-as-positive — not privation, not sensuality, but the active reversal of indissoluble principles.
The "drive-to-know analogous to reproductive drive" essay: cited by Schelling at Freedom Essay p. 681 (note 104). Baader's "On the Analogy between the Drive to Know and to Procreate" — grounds Schelling's distinction between scientific inspiration (disciplined dialectic) and "faun-like appetite" (undisciplined feeling).
"On the Assertion That There Can Be No Wicked Use of Reason" (reprinted as Supplementary Text 2 to the Freedom Essay volume): rebuts the Jacobian / Enlightenment claim that reason cannot be put to evil use. "Evil men would announce themselves as devils if that which is animalistic were still to give them a kind of (heteronomic) goodness." Evil is a positive use of reason, not its absence.
Catholic-theological orientation: distinguished Baader from Schelling and Hegel (both Protestant Lutheran by background) and Boehme (Lutheran). His Catholicism shapes his Böhme-reading: he reads Böhme through a sacramental-ontological frame that secular German Idealism does not share.
Co-founder of the University of Munich (1826): institutional figure; Schelling was at Munich 1806–1820 and again from 1827; their personal-philosophical collaboration is a real intellectual relationship, not just textual influence.

The disease-analogy

The disease-analogy is the operative figure throughout Schelling's Freedom Essay treatment of evil. Schelling's attribution (Possibility of Evil, p. 481):

"The most fitting comparison here is offered by disease, which, as the analogue [Gegenbild] of evil, is of much greater significance than commonly believed."

The Baader-supplied analogical reasoning: just as disease is not the absence of health but the positive disorder of health's elements (fever as inner heat, organic dissolution as misalignment of parts), evil is not the absence of good but the positive disorder of the same forces that constitute the good. Health is restored by "reconstruction of the relation of periphery to centrum"; good is restored by re-aligning self-will with the universal will.

The analogy does structural work, not just rhetorical work. It supplies Schelling with:

The positional language (centrum/periphery) for evil's structure
The "I-hood ruling into the periphery" formulation
The active-disorder (not absent-order) ontology of evil
The medical-naturalistic register that grounds the moral-metaphysical claims

See evil-as-positive-reversal §"Disease/health analogy."

"Wicked Use of Reason" (Supplementary Text 2)

Baader's short essay against Jacobi's claim that reason cannot be put to evil use. Central thesis: evil is not the regression of man to animal but a perverse humanization of animal ends — corruption uses reason, not bypasses it. "Man can unfortunately only stand above or under animals."

The argument: animal-being is indifferent toward good and evil (ignorant of both); "evil men would announce themselves as devils if that which is animalistic were still to give them a kind of (heteronomic) goodness." The polemic is directed against the moralistic position that locates evil in the "animal in man" — Baader argues this is exactly backwards: the slavery of vice is not service-to-animal but the prior inner enslavement that makes use of the animal.

The essay also contains the "denial as positive act" formulation: the denial of evil's positive character is "not... a merely passive ignoring but rather a positive, dynamic, and... violent act of the mind" — i.e., refusing to recognize evil's positivity is itself an evil act of reasoning.

The drive-to-know / drive-to-procreate analogy

Baader's essay "On the Analogy between the Drive to Know and to Procreate" (Über die Analogie des Erkenntnis- und des Zeugungs-Triebes, in Sämmtliche Werke vol. 1, 39–48) is cited by Schelling at Freedom Essay p. 681 (note 104). The analogy: the drive to know is not a disinterested cognitive faculty but a productive drive with the same structural shape as procreative drive. Both involve:

A yearning (Sehnsucht) toward an other
A transformation of the knower/lover through the act
A productivity that exceeds the moment of contact

This grounds Schelling's distinction between scientific inspiration (disciplined dialectical engagement with the matter, the eros-driven philosopher) and faun-like appetite (undisciplined feeling that mistakes its own immediacy for knowledge). The analogy is not reductive (knowing is not procreation) but structural (both involve the same form of productive yearning).

Baader as Böhme-mediator

Baader was Schelling's primary route into Böhme's theosophical apparatus. Trained as a physician and engineer, Baader spent years systematically reading Böhme (from c. 1786) and translating Böhme's theosophical vocabulary into philosophically-responsible German Idealist terms. Schelling at Munich (1806–1820) had ongoing personal-philosophical conversations with Baader; the Mysterium Pansophicum Schelling reprints as Supplementary Text 1 is the Böhme text Baader had taught him to read.

Editors' Introductory Note (raw line ~1867): "Baader was one of Schelling's closest friends and collaborators in Munich. Schelling explicitly acknowledged Baader's influence on his own reading of Boehme."

Catholicism and the late falling-out

Baader was Catholic by birth and remained so throughout his career; this distinguished him from Schelling and Hegel (Protestant Lutheran background) and shaped his philosophical orientation toward sacramental-ontological framings that secular German Idealism does not share. Baader saw Böhme as the Protestant theosophist whose insights Catholic theology could absorb and systematize.

The Schelling-Baader friendship cooled after 1830 over disputes about the proper relation of philosophy and theology. Baader maintained that philosophy must be ancillary to theology; Schelling's emerging positive philosophy (Berlin lectures, 1840s) treated philosophy as autonomous (though oriented toward what theology calls God). The breach is real but does not erase the earlier deep collaboration.

Open Questions

Whether Schelling's debt to Baader is primarily terminological (centrum/periphery, disease/health) or substantive (the entire structural-positional ontology of evil) — Schelling's attribution is explicit, but the depth of Baader's contribution is contested in Schelling scholarship.
Whether Baader's Catholic-theological framing distorts his Böhme-reading — Baader systematizes Böhme into vocabulary that German Idealism can use, but does this systematization preserve or transform Böhme's content?
Whether the late Schelling-Baader falling-out reflects a genuine philosophical disagreement (over the relation of philosophy and theology) or a more contingent personal rupture — biographically uncertain.
