In faith is the truth which is essential to the existing human being. Reason through its investigations comes ever-closer to the whole truth of things, though it is never satisfied. Reason certainly cannot reach God through an investigation of nature, as was argued earlier. Yet it is vital for human beings to find God without delay, as their salvation depends upon it. It seeks God with a passion which has no limits, an infinite passion.
Subjective truth is found in the intensity of the passion.
It culminates in faith, which overthrows reason altogether. Kierkegaard had stated in the Fragments that the highest pitch of any passion is to will its own downfall. This is the highest point an existing individual can attain.
