On What We Think



These pages highlight our founder Dominic's subjective views on the ever-changing range and scope of subjects that Halcyon focuses on.

This is less a blog than a set of irregularly updated and often fragmentary views - on ideas and values, places and people - evolving over time into mini essais which pay humble homage to the peerless founder of the genre. Our writing is provisional, always open to change as new thoughts and ideas emerge.

The kaleidoscope is Halcyon's prime metaphor, encouraging us to embrace change and to view issues through an ever-moving series of lenses.
