Abstract
Being is simultaneously knowing and unknown, rooted in man's spirit-matter composition. The dynamic unity in diversity provides the fundamental _Schwebe (oscillation, tension) of thought. In it sensibility is one with and diverse from intellection. In intellection form is diverse from and identical with _esse. Being's grade of self-presence grounds objective analogy to which corresponds the subjective analogy of sensibility, abstraction, and judgment. These operations reflect the ways of affirmation, negation, and eminence. A unity in diversity exists among sensibility, abstraction, and judgment. Rahner emphasizes identity or diversity according to need, but stressing judgment, he risks relativizing formal abstraction
