思考
To think is to confine yourself to a single thought that one day stands still like a star in the world's sky.
The most thought-provoking thing in our thought-provoking time is that we are still not thinking.
Language is the house of being. In its home man dwells. Those who think and those who create with words are the guardians of this home.
We have not yet learned to think, but we are learning.
Thinking is the hardest work there is, which is probably the reason why so few engage in it.
