The title Night Vision refers firstly to the night vision goggles that enable soldiers to see through the darkness in order to destroy and kill, and secondly to a vision of the political and ecological night that threatens humankind, but also to the faint possibility, grounded in personal relationships and cultural values, that we will see through and somehow transcend this night. The book is a major expression by a veteran poet of searchingly reflective and finely articulated thought. Its subjects and scope extend from the anxious urban landscapes of Vancouver and Calgary to the conflicts and terrors, historic and ongoing, in the US, Latin America, and Europe.
