Following the Kantian “Copernican revolution,” Husserl’s phenomenology is the most powerful idealistic reformalization in twentieth century philosophy. He “corrected” Kant’s transcendental deduction and second-order investigation of mind by arguing that thoughts, associative memory, and affects were available to phenomenological description. In his mature, 1920s investigation into passive synthesis and the complexity of “subjective” time, Husserl approached affects in light of dynamic forces running up and down the temporalizing flux of consciousness. As “retentions,” they joined representations, sometimes clustering around the Schwelle des Bewusstseins (threshold of consciousness), and returning through association. With the transcendental “ego” defined as a universal flow, experiences within the latter, which Husserl defined as retentions and protensions, remained active and betokened in memory, phantasy, and affects.
