Søren Kierkegaard
He wrote many philosophical books about faith, existence, emotions, and feeling. He disliked people who tried to make Christianity political and people who tried to limit the single individual in favour of groups of many people. Many people have found his works interesting and have said that they were great works of philosophy. Ludwig Wittgenstein, a 20th-century philosopher, thought Kierkegaard was "by far, the most profound thinker of the nineteenth century".
