"Kierkegaard was interested in the development of the existent, individual, concrete human personality. Its chief Kierkegaardian stages are the esthetic, the moral, and the religious, and they form a striking contrast to Comte’s trio: the theological, the metaphysical, and the scientific. For one thing Kierkegaard’s highest stage of human existence is the religious, while Comte’s is the scientific; for another, the Kierkegaardian personality’s journey through its stages is absolutely free."
