In The News on Sunday Aziz Ali Dad reminds us how to think.

Thinking demands time to conceive and produce the idea.Thinking takes time to furrow in the soil of being to sow seeds to produce thought within us. But we do not have patience and time for thinking to take its root within our being. Seen in this way, thinking seems to be a vow to give our mind to an enduring question with no lasting answers. Providing cue to the learning to think, Martin Heidegger states, “We learn to think by giving our mind to what there is to think about.”

I assume that's from "What Calls For Thinking?": "We learn to think by giving heed to what there is to think about."; p. 370.  ¶ 8:04 AM
