Today, I was reading in Kierkegaard’s On The Concept of Irony and discovered that Fichte had expressed his thoughts on infinity as well. In Part Two, Irony After Fichte, it reads:

“[Referring to Kant’s das Ding an sich (thing-in-itself):] This question was raised by Fichte. He removed the difficulty with this an sich by placing it within thought; he infinitized the I in I=I. The producing I is the same as the produced I. I=I is the abstract identity. By so doing he infinitely liberated thought. But this infinity of thought in Fichte is, like all of Fichte’s infinity (his ethical infinity is ceaseless striving for the sake of this striving itself; his aesthetic infinity is ceaseless producing for the sake of this producing itself; God’s infinity is ceaseless development for the sake of development itself), negative infinity, an infinity in which there is no finitute, an infinity without any content. When Fichte infinitized the I in this way, he advanced an idealism beside which any actuality turned pale, an acosmism in which his idealism became actuality even though it was Docetism. In Fichte, thought was infinitized, subjectivity became the infinite, absolute negativity, the tension and urge.”

Kierkegaard recognizes this infinity as headed in only one direction by calling it negative. But true infinity should be both positive and negative. I believe that this can be proven.
