 Ludwig Wittgenstein was immensely influenced and humbled by Kierkegaard, claiming that "Kierkegaard is far too deep for me, anyhow.He bewilders me without working the good effects which he would in deeper souls".Karl Popper referred to Kierkegaard as "the great reformer of Christian ethics, who exposed the official Christian morality of his day as anti-Christian and anti-humanitarian hypocrisy".
