Abstract
Kierkegaard never doubted that the object of thought is real. The idea that thinking could be about nothing is unintelligible. "That the content of my thought is in the conceptual sense needs no proof, or needs no argument to prove it, since it is proved by my thinking it". There is a problem, however, concerning the relationship of being "in the conceptual sense" to being in whatever other senses it may have. Being is not of a piece, but is inwardly differentiated by its own modalities. The problem of the relation of thought and being cannot be understood unless we are aware of the various meanings of "being," and similarly, of the meaning of "thought."
