The 'public' is a phantom, the phantom of an opinion supposed to exist in a vast number of persons who have no effective interrelation and though the opinion is not effectively present in the units. Such an opinion is spoken of as 'public opinion,' a fiction which is appealed to by individuals and by groups as supporting their special views. It is impalpable, illusory, transient; "'tis here, 'tis there, 'tis gone"; a nullity which can nevertheless for a moment endow the multitude with power to uplift or destroy.
Karl JaspersGreatness of mind becomes an object of love only when the power at work in it itself has a noble character
Karl Jaspersthe essence of philosophy is not the possession of the truth but the search for truth. ... Philosophy means to be on the way. Its questions are more essential than its answers, and every answer becomes a new question.
Karl JaspersAs a universal history of philosophy, the history of philosophy must become one great unity.
