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 JaspersPhilosophic meditation is an accomplishment by which I attain Being and my own self, not impartial thinking which studies a subject with indifference.
Karl JaspersIf philosophy is practice, a demand to know the manner in which its history is to be studied is entailed: a theoretical attitude toward it becomes real only in the living appropriation of its contents from the texts.
Karl JaspersThe great philosophers and the great works are standards for the selection of what is essential. Everything that we do in studying the history of philosophy ultimately serves their better understanding.
Karl JaspersEven scientific knowledge, if there is anything to it, is not a random observation of random objects; for the critical objectivity of significant knowledge is attained as a practice only philosophically in inner action.
