Some among us have a clear sense of what is right and wrong – for themselves personally if not for everyone else. They have a reassuring certitude and steadiness which can serve as a reference point by which others may navigate. There are others who live in a state of uncertainty, constantly re-thinking their responses to changing circumstances, trying to hold onto what seems fundamental but impelled to reinterpret, often even unsure where lies the boundary between the fundamental and the interpretation…

Please be patient, those of you who have found a rock to stand on, with those of us who haven’t and with those of us who are not even looking for one. We live on the wave’s edge, where sea, sand and sky are all mixed up together: we are tossed head over heels in the surf, catching only occasional glimpses of any fixed horizon. Some of us stay there from choice because it is exciting and it feels like the right place to be.

Philip Rack, 1979
