Jonathan Ree discussed Kierkegaard @ In Our Time.
Ree states that Kierkegaard believed that Socrates was about taking down pretensions to knowledge, not the building up of philosophical systems, such as that of Hegel. I can think of no one who more attacked pretensions to knowledge than Nietzsche (Hume comes second). Perhaps Nietzsche was Socrates truest disciple – now that’s irony.
