If 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 Jaspers
Even 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 Jaspers
Only then, approaching my fortieth birthday, I made philosophy my lifes work. – Karl Jaspers
The history of philosophy is not, like the history of the sciences, to be studied with the intellect alone. That which is receptive in us and that which impinges upon us from history is the reality of mans being, unfolding itself in thought. – Karl Jaspers
Everyone who achieves success in a great venture, solves each problem as they came to it. They helped themselves. And they were helped through powers known and unknown to them at the time they set out on their voyage. They keep going regardless of the obstacles they met. – W. Clement Stone
