Philosophy can only be approached with the most concrete comprehension.
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 man's being, unfolding itself in thought.
Philosophy as practice does not mean its restriction to utility or applicability, that is, to what serves morality or produces serenity of soul.
The 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.
My own being can be judged by the depths I reach in making these historical origins my own.
I discovered that the study of past philosophers is of little use unless our own reality enters into it. Our reality alone allows the thinker's questions to become comprehensible.
