"Although man is under an obligation to become morally worthy, he is unable to achieve this goal precisely because Kant's critical method, rooted in autonomy, makes it impossible either for reason or for God to help, widening the gap between God and man. Thus, an alternative to Kant's critical method, rooted in Enlightenment rationality, is necessary to warrant optimism. Understanding the despair of the Kantian man, whom God alone can help, Kierkegaard, in his 'Sickness unto Death', advances a compelling and conclusive existential argument which incorporates theological and historical analysis. Given that man is radically evil and finite, it is absolutely impossible for man to close this gap. Kierkegaard argues that God closes the gap by becoming incarnate." - Vanneya P.
