On the question of the world as a whole, science founders. For scientific knowledge the world lies in fragments, the more so the more precise our scientific knowledge becomes.

Only then, approaching my fortieth birthday, I made philosophy my life's work.

We must learn to talk with each other, and we mutually must understand and accept one another in our extraordinary differences.

Reason is like an open secret that can become known to anyone at any time; it is the quiet space into which everyone can enter through his own thought

It has become obligatory to fulfil a function which shall in some way be regarded as useful to the masses...Even an articulated mass always tends to become unspiritual and inhuman. It is life without existence, superstition without faith. It may stamp all flat; it is disinclined to tolerate independence and greatness, but prone to constrain people to become as automatic as ants.

Everything depends therefore on encountering thought at its source. Such thought is the reality of man's being, which achieved consciousness and understanding of itself through it.

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.
