Philosophy is tested and characterised by the way in which it appropriates its history.
Karl JaspersWhen language is used without true significance, it loses its purpose as a means of communication and becomes an end in itself.
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.
Karl JaspersThe more determinedly I exist, as myself, within the conditions of the time, the more clearly I shall hear the language of the past, the nearer I shall feel the glow of its life.
