" Perhaps thinking too is just something like building a cabinet. At any rate, it is a craft, a 'handicraft', and therefore has a special relationship to the hand. In the common view, the hand is part of our bodily organism. But the hand's essence can never be determined, or explained, by its begin an organ which can grasp and (...) the hand is infinitely different from all the grasping organs.. different by an abyss of essence. (...) But the craft of the hand is richer than we commonly imagine. (...) The hand reaches and extends, receives and welcomes - and not just things. The hand extends itself, and receives its own welcome in the hands of others. (...) But the hands' gestures run everywhere through language, in their most perfect when man speaks by being silent. (...)Every motion of the hand in everyone of its works carries itself through the element of thinking, every bearing of the hand bears itself in that element. All the work of the hand is rooted in thinking."

Martin Heidegger, "What calls for thinking?"
