Power makes knowledge sufficient Whether it is civil rights' violations in many countries, whether it is the increasing numbers of unemployed people in our own country, whether it is the homeless we see on our way to work, it isn't as though we don't know. But there is that horrible realization that, while the knowledge of facts may be a necessary condition for action, and we talk about democracy in civic action, it is unfortunately not a sufficient one. While knowledge may be a necessary condition, it may in fact be a less necessary condition that the one that makes that a sufficient condition, and that is access to power. Ursula M. Franklin, Every Tool Shapes the Task power
The axis of movement Moving in the city means constantly changing the axis of movement. In general, lateral movement is confined to a single plane, what’s called grade, the ground level.

Rooftop circulation is the domain of Fantômas, of cat burglars and fleeing criminals, of lovers, and of those acrobatic enough to negotiate the gaps between buildings.
