The publication of the 1790 Essay on Transcendental Philosophy marked a significant intervention in contemporary metaphysics, challenging established structures of thought. Born in 1754 within the Grand Duchy of Lithuania, this philosopher navigated intellectual circles in Berlin, Hamburg, and Amsterdam, producing a body of work primarily written in German and Hebrew that sought to resolve deep-seated contradictions in 18th-century epistemology.
Formative Years and Education
Born as Shlomo ben Joshua in Žukaŭ Barok, he received early training in Torah and Talmud. By age fourteen, he was teaching Talmud to support himself. His intellectual horizons expanded after encountering a rabbi in Slonim, which provided access to texts on physics, optics, and medicine. During this period, he developed a skeptical perspective on religious mysticism, notably critiquing the claims of the Maggid of Mezritch while simultaneously acknowledging a preference for those moral teachings over his previous instruction.

Relocating to Berlin in 1780, he integrated into the Haskalah movement under the influence of Moses Mendelssohn. His career was marked by instability, including an expulsion from Berlin in 1783 due to his adherence to Spinozism. He later attended the Gymnasium Christianeum in Altona to refine his grasp of natural sciences and German. Despite periods of homelessness and financial dependence on wealthy patrons, he eventually secured a stable position as a tutor in Silesia after divorcing his wife, Sarah, in the late 1780s.
Metaphysical Critiques
His primary philosophical contribution involves the rejection of the thing-in-itself as an unthinkable concept. He argued that since the object of thought must reside within consciousness, anything existing outside it is inaccessible to human reason. By synthesizing elements of Humean skepticism with his own doctrine of differentials—borrowing from calculus to explain the transition from sensation to concept—he sought to collapse the dualism between understanding and sensibility, viewing all cognitive processes as variations of mathematical intuition.
