In the new thinking, the method of speech replaces the method of thinking maintained in all earlier philosophies. Thinking is timeless and wants to be timeless[….] Speech is bound to time and nourished by time, and it neither can nor wants to abandon this element. It does not know in advance just where it will end. It takes its cues from others. In fact, it lives by virtue of another's life, whether that other is the one who listens to a story, answers in the course of a dialogue, or joins in a chorus; while thinking is always a solitary business, even when it is done in common by several who philosophise together.

Rosenzweig, The New Thinking
