The philosophical work of Klaus Düsing can be understood in various ways, both affirmatively and critically, through the concept of "Enlightenment." If Enlightenment is understood as a theoretical conception that fundamentally emphasizes the autonomy of the subject, a pedagogical stance that promotes that autonomy, a methodological claim for clarity, or an interpretative approach that takes into account and reveals the historical roots of philosophical texts with the aim of assessing their explanatory value and appreciating their systematic significance independently of tradition and bias, then such enlightenments are characteristic of Klaus Düsing's work. With his systematic work "Models of Self-Consciousness," Klaus Düsing has introduced a new conception of concrete, autonomous subjectivity into the currently vibrant debate surrounding the problems of subjectivity.
